To improve the wireless speed or
range, it is highly recommend to work on the following common solutions:
Choosing the best locations
Optimising configuration of the
device
Upgrade the equipment
Symptom
Weak wireless signal showed, low
wireless speed or range.
Cause
The factors most frequently
affecting the wireless signal:
1. Intrinsic factors
Transmission Distance: Regarding on the wireless device
particularly working on 5GHz band, it will be more sensitive to the obstacle.
Though there will be more clear channels than those of 2.4GHz bands, the
wireless signal will be reduced significantly and transmit in shorter range due
to higher frequency. Antenna: Omni-directional antennas and directional
antennas. Omni-directional antennas are resembled in our home products like
wireless router or wireless ADSL2+ Modem Routers, they radiate horizontally all
around, but are weaker upward or downward as the picture shows.
While a directional antennas
radiate strongly in a particular direction which are usually used for high
power outdoor products. The gain of a directional antenna increases, also with
the coverage distance, but the effective coverage angle decreases. Generally,
the higher gain value of an antenna, the better directional ability will be.
For directional antennas, the
lobes are pushed in a certain direction and little energy is there on the back
side of the antenna. Please refer the picture below.
This phenomenon will be more
significant once you deploy the High-Gain antenna, so we recommend that to
confirm precise on horizon direction otherwise there be unexpected dramatic
signal loss.
Wireless Communication
Performance: The
higher performance transmission rates, the better ability.
2. Extrinsic factors
Physical Barriers, such as wall or
clapboard and so on;
Other similar devices and other
sources such as microwave ovens, cordless phones or other technologies
that use the same band as Bluetooth or security devices.
There are more than one AP or wireless
routers working in the same Channel.
The location where an AP or wireless
router is placed. Do your better to place the device at a higher location
to reduce the barrier's countercheck.
Solution
Here are some solutions to
improve the weak wireless signal as the reference, some problems caused by the
inherent property of wireless connection.
Choosing the best locations
1. Antennas should be positioned
for best location and direction
Deploy the antenna in good location
and correct angle, and also make sure your wireless client devices are in
the coverage;
For multi-story buildings wireless
coverage, we recommend to placing antennas at 45 degrees (diagonally) or 0
degrees (straight out parallel to the floor) which will be more effective.
Since antennas always transmit weakly at the base, do not place your
wireless client device at the bottom of TP-LINK wireless router or access
point.
Please check the following
picture as reference and you can find easily that A point is recommend while B
or C is in not good location.
2. Try best to avoid the
extrinsic interference
>Avoiding the physical
interference in the wireless coverage, each wall or ceiling will have a
negative effect on wireless radio particularly the ones built by solid
metal material;
Keep your device away from various
electromagnetic noise sources that generate RF noise, like microwaves,
Monitors, electric motors, copying and fax machines, etc.
Optimise configuration of the
device
For TP-LINK wireless products, we
recommend to do corresponding settings to avoid the interference from other
networking and radio frequency equipment. First, please log into the
product and you can refer to this link as guidance. Here we take TL-WR1043ND
user interface as an example and then please go to Wireless->Wireless
settings and change the channel settings, the default value is Auto and here we
recommend select 1, 6 or 11 if you suffer high wireless interference.
For 802.11b and g, there are 14
channels designated in the 2.4 GHz range and three non-overlapping channels
recommended: 1, 6 and 11 (1, 7 and 13 in part European region, please obey your
local regulations or laws).
Sometimes the
"well-known" channels will be also crowded and we recommend to select
the appropriate one adjusted to your local environment.
Upgrade the equipment
If you want to have a big improvement
immediately and boost the wireless throughput, you can also choose to
upgrade a combination of antennas or other wireless equipment to enhance
the wireless transmission;
If you are in a congestion wireless
environment, the wired connection can be taken into consideration and the
TP-LINK Powerline equipment is a good alternative.

Tech Specs As per tp-link.in and the product box :
Speed Test using speedtest.net on my Lenovo g50-80
One could also use html 5 based speed tester like speedof.me for 100% accuracy
My Conclusions :
rugged router as compaired to others in same category in design and companion app with 3 5db antenne. An ideal for a house of 950 sq feet area. A big drawback are its lights in front as they don't blink so difficult to make out connectivity and only 1 lan port light so u cant see what is connected on which port number.
UI :
Good user interface divided in 3 parts with menu on left , functions in middle and help on makes it more intuitive ui as not seen on some famous brands like Netgear DGN3200V4 used by me previously an N300 router. In my view best ui with help I have ever come across ever. only drawback not having GUI as P5 or ASUSWART interface. But is a great for day to day configs of network and is easy to use even by a newbe. How ever the best part about TP-LINK is router firmware simulation on there tp-link.in website. PRICE: Best in the class of budget routers offering usb support for print and media along with DLNA and FTP server. falling between 2150 k to 2500 k in the local market. and ideal replacement for your old routers.
TIPS:
1) check your laptop and mobile adapters before buying your modem. eg: Intel dual band wireless-AC3160 : A 1x1 802.11AC Wi-Fi plus Bluetooth adapter that delivers upto 433 Mbps and Intel dual band wireless-AC7620 : A 2x2 802.11AC Wi-Fi plus Bluetooth adapter that delivers upto 867 Mbps. do check www.intel.com/wireless for more on adapters as buying a P5 for that matter wont make any impact as receving end is a pipe and delivering end is a tunnel like 1300Mbps on Intel dual band wireless-AC3160 where speed is 433 Mbps only .
2) Be budget wise : don't by routers based on its speed as price also increases . like an n300 router will give you max speed of 150 (funda of 10/100 Mbps) so also buying GIGABIT Port router wont help if you have adapters like Intel dual band wireless-AC3160 on your laptop or desktop. 3) Buy only trusted brands don't experiment with new ones.
If you're in the market for a smartwatch or fitness band, here's what you should look for and what you should know before buying. (Hint: it's still a messy, muddy place.)
Smartwatches, smartwatches everywhere. Fitness bands, too. Wearable tech wants to be in your life, but do you feel like letting it in?
Wearable tech is still on the rise: according to market researcher Canalys, 7 million wearable bands shipped in the first quarter of this year, a growth of 150 percent over the previous year. By IDC's earlier estimates, 45.7 million wearable bands will ship by the end of this year, with a yearly forecast of 126.1 million by 2019.
And yet, there's so much that feels hard to recommend. When I took a look at the wearable landscape back before the Apple Watch, it seemed like a good time to wait. Now, past the halfway point of 2015, lots of new products have finally emerged: The Apple Watch, Pebble Time and new fitness trackers from Jawbone, Fitbit and Garmin are all available for purchase. And...it's still a muddy territory.
That's because wearable tech is still largely unnecessary for most people. For the vast majority, these devices still skew somewhere between a toy and a tool -- albeit one that is often somewhat redundant to your smartphone. Bands and watches can do it better, though, and there are some options out there that range from pretty decent to downright solid. But buyer beware: While we've reached a lull in the wearable tech onslaught -- nearly all of the previously announced products have been released -- know that whatever you pick now might feel outdated in just a year.
That said, are you ready to take the plunge? Consider: Do you want to make sure you don't miss messages on your phone? Care about getting a bit healthier via a gadget? Do you run a lot? Are you an early adopter of status-symbol personal tech? Then maybe a smartwatch or fitness band is for you.
There are now dozens of smartwatches and fitness trackers now available, but below you'll find our recommendations right now, and why they stand out. Also make sure to check out our continually updated list of best wearable tech.
What to look for in a smartwatch or fitness band:
Design: Does it actually appeal to you? This is a matter of personal taste.
Phone support: You'll need Bluetooth 4.0, and your phone and OS need to be supported.
Is it waterproof, or swim-friendly? Do you shower with your watch on?
Battery life: Our baseline is an average of three days for a smartwatch, seven days average for a fitness band -- but very few current products meet those expectations.
What apps does it run? Pebble, Android Wear and Samsung Gear all use different apps.
Color screen, or black and white, or something else, or none at all? Some screens are always on.
Can it recognize your voice, and can it act as a speakerphone? Do you want that?
Is there a heart-rate monitor? How does it track fitness? Heart-rate monitors vary greatly, too.
What apps and ecosystems is it compatible with? For fitness bands, this is a big deal.
Apple Watch: A good iPhone accessory set to get even better
The Apple Watch has made the biggest splash, with the biggest brand recognition, of any piece of wearable tech. That doesn't mean it's a must-have. The Apple Watch requires a recent (iPhone 5 or later) iPhone, and runs its own App Store-compatible apps. But its mix of easy-to-access notifications, fitness tracking, premium design and extra bells and whistles set it apart from most of the competition. It's expensive, though, and its battery life isn't great (one day or slightly more). And, its selection of third-party apps just don't load fast or work that well.
It's also an unfinished product. A wealth of on-board apps are coming this fall along with a revamped WatchOS 2, a software revamp that will hit by the end of the year. These could both make the Apple Watch far better than it currently is. But if you wait until the fall, would you consider waiting even further until next year and an inevitable Apple Watch 2? I say you at least wait until this fall to see what the new changes are like, unless you're desperate to start playing with one today. Even with its flaws, it's one of the best smartwatches around right now. And, if you're an iPhone user, this edges out the Pebble in nearly all regards (except battery life).
Pebble Time: Pebble's latest watch adds color and a new UI, but still feels the same.
Pebble: Old reliable
Think of the Pebble watch as the BlackBerry of smartwatches: functional, traditional, somewhat unsexy, but once you become a serious user you'll probably be hooked. Pebble watches don't have touchscreens, lack heart-rate tracking, and have apps that feel retro and not all that advanced compared to what Apple Watch, Samsung Gear and Android Wear offer. But the Pebble works across Android and iOS, has hundreds of apps and watch faces that are mostly free, has battery life that lasts nearly a week, an always-on reflective display, and can be worn while swimming and showering. It's like a regular digital watch, turned smart.
You can pick from several models. The oldest Pebble ($99, £100 or AU$149) is still decent for its price, but ugly and scratch-prone. The step-up Pebble Steel ($150, £149 or AU$289) adds a metal frame and Gorilla Glass, but has the same black-and-white screen. These Pebbles can only store eight apps or watch faces at a time. The new Pebble Time ($199 or £180) looks more toy-ish than the Casio-retro Pebble Steel, but adds a reflective color screen, storage for dozens of apps, and a revamped interface with a new timeline view for upcoming events. It also has a rear port that could eventually be used for hardware-extension watchbands.
Buy the cheap Pebble if you want something basic to catch messages and info; consider the Pebble Time for better futureproofing. My sentimental favorite is still the throwback Pebble Steel for its angular looks. The Pebble is the best place to go for a decent set of basic functions in something that feels more like a regular digital watch.
LG Watch Urbane: classic design, one of our favorite Android Wear watches.
Android Wear: Google's smartwatch offers lots of options
Android phone owners have a lot of smartwatch options. There are over half a dozen Android Wear smartwatches to choose from: the LG G Watch , Samsung Gear Live , Moto 360 , Asus ZenWatch , Sony SmartWatch 3 , LG G Watch R andLG Watch Urbane . They all run a common OS and apps, and work with tons of Android phones. Because Android Wear watches have been around for a year, you can probably catch a sale on one and get a good deal. These watches vary in features slightly, something to consider when buying: some lack Wi-Fi for extended connectivity, and Sony's is the only one that has GPS. Some lack heart-rate tracking. They all have different designs, with round or square screens, but they all run the same set of apps and watch faces.
Battery life is mediocre, and Google's watch OS and interface, while it's been getting better and better, still feels imperfect and sometimes awkward. You can do a lot of things with Android Wear, like respond to messages, use apps and get map navigation. But they all require a phone to be paired and they lack any speakerphone for making calls.
My favorite is the LG Watch Urbane, but it's also expensive. The Moto 360 is a good choice now that its price has dropped. It has built-in Wi-Fi, which enables a longer-distance bridged connection with your phone across different Wi-Fi networks, included in Android Wear's latest software update. For the right price, an Android Wear watch can be fun. But most of them still feel rough around the edges and more like a chore than a life-altering tool...and that's mainly due to Android Wear's software.
Samsung Gear watches: Skip for now
A note on Samsung watches: The company has made many smartwatches, most of which work exclusively with certain Samsung phones. In 2015, thus far, Samsung has had no new smartwatches at all. Samsung's watches offer more hardware features, and also have onboard speakerphones like the Apple Watch. (TheSamsung Gear S , released last fall, even doubles as a stand-alone phone with its own SIM card.) But Samsung has a new watch on the horizon, and probably a new app ecosystem. For that reason, and others, you should skip Tizen-based Samsung Gear watches for now (that's every watch except the Samsung Gear Live, an older watch that runs Google's Android Wear).
If you have a Samsung phone, you can use an Android Wear watch (see above). The apps are better, and the support is greater. You can't make phone calls from your wrist, though.
Despite smarter smartwatches like Apple Watch, fitness bands are doing just fine. That's because they're cheaper and more purpose-built. Fitbit is the dominant brand, but it's not necessarily my favorite. That being said, you're bound to find the most people you know using Fitbits, which helps because you can compete socially with them.
Fitness trackers are about all-day 24-hour activity monitoring. Some of them track active exercise, but most lack GPS functions that serious runners crave. These are, mostly, for the average person looking to get a bit healthier.
If you're getting a Fitbit, get the Fitbit Charge HR . It doesn't cost much more than the regular Fitbit Charge, and adds 24-hour heart-rate tracking. It also tracks sleep, has decent battery life and is easy to use.
Jawbone makes a fantastic fitness app, but its latest hardware isn't all that great. The Jawbone Up2 lacks heart-rate, but that's fine: you're better off saving $80 and skipping the Up3's bare-bones, weird heart-rate functions.
On the cheaper end, go with a Misfit Flash : its long battery life and shower-friendly water resistance in a $50 gadget can't be beat.
You can also pick a semi-smart watch with fitness built in: the Withings Activite Popfeels like a regular analog watch but has eight months of battery life, can track swimming, and syncs steps and sleep over Bluetooth to your phone. It's a sign of where fitness tracking might head next: to your everyday watch.
In general, go cheap with fitness bands, and skip heart-rate for now unless you're a serious workout warrior or runner. Heart-rate tracking isn't all that accurate unless you're using a chest strap monitor, and most fitness apps don't help you understand your heart rate in any meaningful way.
Do-it-all fitness gadgets (like the Basis Peak and Microsoft Band ) have too many compromises to feel like the right solution for most people. But these types of comprehensive bands point to where fitness bands might aspire to next.
The Polar M400, one of our favorite running watches.
Running watches: Power tools
If you're a real runner, there are plenty of purpose-built solutions on the market. Garmin, Timex, Polar and many others have dedicated running watches. These sync data with your phone or PC, but their advantages over fitness trackers tend to involve longer battery life, GPS, and more detailed runner-oriented data.
Stay tuned for more reviews, but our favorite right now is the Polar M400 : its combination of smartwatch-like notifications (for iOS), GPS and all-day activity tracking make it stand out. The Garmin Forerunner 15 is a solid entry-level running watch, but it lacks Bluetooth for phone syncing. Having on-board GPS and a wealth of runner-targeted stats at your fingertips, plus a display that maximizes easy reading of those stats, still makes these watches stand apart from most fitness bands and smartwatches.
Apple Watch, LG Watch Urbane, Pebble Time, Moto 360.
What comes next?
Look for apps and ecosystem to drive wearables for now. The arrival of better apps on the Apple Watch will probably happen in tandem with improved Android Wear apps and, eventually, a new Samsung watch with its own apps. Connecting to smart homes, connected devices and onboard watch sensors in new, innovative ways could start making smartwatches feel a lot more interesting by mid-2016. But that's all speculation. At the moment, smartwatches feel caught up in a singular problem: they're mainly phone accessories, and as a result they feel like luxuries rather than necessities.
For fitness bands, improvements in heart-rate sensors and apps that interpret heart rate in helpful ways still need to emerge to justify the purchase for most people.
Finally, there need to be new steps in sensor technology and battery life. Will there be new types of sensors beyond barometers, heart rate sensors, and accelerometers? It's possible, but those sensors haven't yet arrived. Battery life on smartwatches is still really limited -- cracking the week-plus barrier would be a huge help. The Pebble Time Steel promises up to 10 days of battery life, but most watches still require charging multiple times a week.
These bigger changes won't come until next year. For now, I'd still either pick a basic fitness band or go with a major-brand smartwatch with app support.
Smartwatch or Fitness Tracker? 6 Questions to Ask Yourself
Credit: AP Images
A year ago, you swore you’d never buy into the hype. Wearable tech was for geeks. And you, a normal, well-adjusted consumer, would do just fine with your laptop and smartphone, thank you very much.
But then something happened. Maybe it was the neighbor who lost 30 pounds with a Fitbit, the thirteenth commercial about the Apple Watch, or the new hire who used a Moto 360 to flip through a presentation deck. All at once, you couldn’t remember why you’d ever doubted. It was time for a wearable device—the only question was which one.
Unfortunately, the choice between a smartwatch and fitness tracker is harder than it looks. Sure, smartwatches can tell time, but you’ll spend many more minutes checking apps and monitoring notifications. And yes, the fitness tracker might seem all about workouts, but the most recent models can measure a whole lot more, including health signals and sleep quality.
With that in mind, here are the six key questions to ask yourself before you purchase one or the other.
When it comes down to it, a smartwatch is a fashion statement first, and a tool second. For fitness trackers, it’s the opposite. The key is deciding which of the two is more important to you.
Before you buy a smartwatch, make sure you're drawn to the way it looks, whether it’s the geeky charm of the Pebble Time, the sleek simplicity of the Moto 360, or the classic face of the LG G Watch R. It’s unlikely you’ll fall in love with any one feature on today’s smartwatches, but if you simply love how it looks in the mirror, you’ll be happy you made the purchase.
Meanwhile, fitness trackers aren’t just ambivalent about fashion—most want you to forget they’re there in the first place. Whether you’re wearing an understated band or abdomen patch, the tracker’s job is simply to transmit all your info quietly and seamlessly—not to stand out at the company lunch or family barbecue. It’s about data, not design.
As a general rule, fitness trackers are cheaper than smartwatches. You can snap up a top-shelf tracker for about $100, while most of the popular smartwatches will start closer to $200—more if you want the best models.
Note: Apple’s average price excludes the $10,000+ Edition models
Then again, you tend to get what you pay for. The most expensive smartwatches come with several fitness-tracking features built in, meaning you get everything—the heart rate monitoring, the notifications, the apps—all in one device.
Think of the smartwatch as a pricey luxury: a full-featured wearable with more settings and alerts than you’ll need. In contrast, the fitness tracker is an affordable compromise: a streamlined wearable with just enough features to do its job.
While the smartwatch tends to out-feature the fitness tracker, there’s one category where the tracker still wins. Naturally, that’s fitness. Both devices monitor simple stats like steps and (in most cases) heart rate, but the fitness tracker tends to provide more detailed metrics, more extensive reports and more granular goal setting.
As such, the smartwatch is a good choice for the casually recreational person—someone who wants to stay active, but who isn’t necessarily counting calories to the decimal place. Meanwhile, professional athletes and serious bodybuilders might opt for the tracker, which keeps the focus squarely on athletic performance and fine-tuned physical goals.
The smartwatch is meant to be seen, admired and shared. It’s why Apple sells brightly colored watch bands for workouts alongside stainless steel link bracelets for dinner parties. It’s why the device will vibrate, chime and flash to get your attention throughout the day.
Meanwhile, most fitness trackers won’t even bother making a sound. They’ll sit silently on your wrist, hidden under your shirt, or clipped on the edge of your pocket. If you relish the fanfare of making calls through a wearable device, grab a smartwatch. If you’d rather people not even know that you’re wearing a gadget, get a tracker.
The smartwatch, quite simply, is made for your wrist. Compare that to the fitness tracker, which boasts at least nine different types of wear, depending on your device of choice: wristband, clip, chest strap, anklebone, headband, headphone, insole, leg strap or mouth guard.
If you prefer wearing on your wrist, this question won’t make the decision any easier. But if you’d rather leave your arms free of tracking devices, consider an alternative-style tracker.
6. Display Quality or Battery Life?
Most smartwatches feature some kind of modestly sized, graphic display, while fitness trackers will give you a few dots or numbers at most. All those shiny pixels on the watches come with a cost, however, and that’s battery life. Many trackers can last a week or more on a single charge, while with smartwatches you’ll be lucky to go two days between plugging in. So it comes down to what’s more important: the convenience of staying unplugged or the eye-candy of a pretty display.
If you’re still undecided, consider getting both. You’ll get all the advanced tracking of the fitness band, next to the class and design-first aesthetic of the smartwatch. You’ll also get twice the positive reinforcement after a run or workout. Just remember: you still only get to count burned calories once.
