The first set of 802.11ac chips is coming, but 802.11n may still exist for many years, both for business and home use. However, the n standard promised 300 Mbps (megabits per second) is rarely implemented, and it has proven to pose significant bottlenecks for 50/100 Mbps broadband connections, 1080p video streams, large-scale backups, and the like. On the enterprise side, some trivial tasks (such as remote desktop or real-time collaboration) are affected by poor Wi-Fi connectivity.
In our tests, we often see the result: with 802.11n connections, the speed of devices that are only a few meters apart (with only one wall in the middle) will drop to only 2-15 Mbps. Here are the problems you will encounter:
A* 0.5-2 Mbps: For this speed, you can handle all the basic chat and mail services, but it will be slower when loading some content-rich websites.
A* 4-5 Mbps: enough to handle all websites and basic video streams
A* 20+ Mbps: This is the minimum speed required for HD streaming. A typical bitrate 720p iTunes TV show is 2-6Mbps, your router needs to compensate for other connected clients and pre-buffer.
A* 50+ Mbps: Supports 1080p movies and air backup.
If you hate such slow Wi-Fi speeds but don't want to go back to Ethernet, we've provided you with some tips to speed things up.
1. Check the ecological settings of your router
Some routers are set to "power save" mode by default, with the goal of saving a few milliwatts. However, this commendable method will reduce bandwidth accordingly. Although the Linksys WRT610N router I trust is not set to this unnecessary power saving mode, I adjust it to the power saving mode to see the effect on bandwidth.
If you pay more attention to bandwidth than saving a few milliwatts, check the router settings, find options called "transmit power" or various Eco modes, and turn them off. Also, check if your router has some "automatic" transfer settings turned on and you should turn it off.
2. Overcome physical laws
Sometimes, the laws of physics also affect wireless bandwidth and signal strength. First, the distance between your router and the wireless adapter has a greater impact on the speed of the network than you might think. There is a rule of thumb here: as long as the distance between the router and the client doubles, the throughput will drop to one-third of the original value. Wireless repeaters (which can cost between $20 and $100) will significantly increase your signal strength.
In addition to distance, other wireless signal killers include objects and elements that affect throughput, namely water and metal. Water will block the 2.42GHz signal, so it's best to take away all objects in your home or office that contain any form of liquid (this includes the radiator and the flower pot, which is not a joke!). At the same time, make sure there is no metal between the router and the client, such as metal furniture and metal plates, high-tech equipment.
Keep in mind that smooth and shiny surfaces reflect signals and affect signal strength.
3. Upgrade the antenna of your router
Packet loss and weaker throughput are usually caused by poor antenna design. The good news is that you can use a more powerful antenna to replace the built-in antenna in your router. This is a bit of a hassle, but it will make you noticeably the difference between a slow connection and a quick connection to the router.
Depending on your setup, you can choose an omnidirectional antenna or a directional antenna (if most devices that require good throughput are in one room).
4. Find the best place to put the router
Using wireless thermal imaging tools to measure the effects of distance, frequency, and building structure on signal strength, there are two recommended tools for NetSpot (for Mac) and Heatmapper (for Windows), both of which can help you track your office. Or the wireless coverage of the home. In our tests, we will show you how NetSpot works: After installing the software, enter a new name in "Site Survey" and click on "Blank Map". You can also choose a floor plan in your home or office to get a more accurate map. If you want to be more creative, I suggest you choose the "Draw Map" function and start drawing your own floor plan. Next, determine the exact distance between the two locations, click "Let's get started", then go to a point and click on your current position on the floor plan:
Obviously, the more points you scan, the more accurate your wireless heat map is. After completing these steps, you will get a map showing the signal strength and showing the throughput of the wireless network.
5. Different CPU frequencies and their effects on wireless signals
Your computer motherboard also runs in the "Gigahertz" spectrum, which is detected by the built-in wireless transmitter. Unfortunately, the higher the noise, the more likely your wireless router will automatically reduce bandwidth (by reducing link rate and avoiding frequency interference). Since the current CPU frequency is dynamic, the wireless adapter needs to constantly adapt to the link rate, which not only causes Mbps changes, but may also cause the connection to be disconnected. Especially on laptops, wireless adapters are usually built into the memory and CPU bus, which is the main source of the problem.
Of course, it all depends on the design of your wireless adapter, but if the above symptoms are the problem you are facing, you may need to configure an external adapter to solve the problem. Some adapters (such as Linksys adapters) have a bracket that is connected by a long USB cable. It is helpful to pull the distance between the wireless adapter and the CPU noise in this way. Of course, this method is not very convenient when you are working outside, but it is a viable option when you use it at home. Typical wireless adapters (such as Linksys AE2500, 802.11n dual-band) or MSI US310EX are very easy to use.
6. Firmware or driver issues
A simple but often forgotten advice is to make sure your router firmware is up to date, especially if you purchase a new router. With the first few firmware updates, bandwidth, feature set and signal resiliency are expected to increase. (My Linksys can only provide full bandwidth to the living room after updating).
Also, make sure that the wireless adapter (whether external or built-in) is always up to date. After upgrading to the next adapter driver version, issues such as standby issues and low performance will be resolved. Although the drivers delivered through Windows Update have become better in recent years, they rarely provide you with the latest and greatest drivers. You can do this:
The first place to view updates is the manufacturer's support page. But if their driver domain is not well maintained, you can go to the chipset manufacturer's website. We often see the chipset of the wireless adapter being acquired and then adopting the new brand name. For example, our Linksys WUSB 600N adapter uses the RT2870 chipset from Taiwanese manufacturer Ralink. So, it's a smart way to go directly to the chipset manufacturer's website to find an update.
Check their support/download page, enter your email address, and get the driver.
To find out which chipset you are using, you can check the spec sheet of the wireless adapter.
7. Choose the right channel
Once your router is set up, it will automatically detect the least crowded channel and set it as the default channel. However, with the advent of new neighbors or offices, this situation may change rapidly: all of a sudden, one channel will be occupied by many routers, while others will not be used. InSSIDer can help you solve this problem: this tool will analyze the entire wireless spectrum and then provide you with details of the home network that has been used for the channel.
I was surprised to find that I was sharing channel 1 with the other four routers. This is not the most ideal situation. Since channel 9 is not being used, I used this channel instead, which helped me significantly improve latency and throughput.
8. Use your router's 5GHz network
The 2.4 GHz frequency is very crowded, not only because the neighbors use the same frequency, but also baby monitors, cordless phones, microwave ovens, and so on. Modern 802.11n routers offer "dual-band", which means they send two network signals: one at 2.4 GHz and one at 5 GHz, which is not crowded and provides more channels. So why don't we jump to 5GHz and enjoy a less crowded and faster wireless frequency? Unfortunately, many device manufacturers believe that they should save money on wireless chips, and only choose 2.4GHz receivers, including all portable game consoles, as well as many Android phones, all Apple iOS devices and Windows Phone. My advice is to activate both networks and connect mobile devices to the 2.4GHz network. Enable 5GHz network for your laptop and desktop.
9. Limit the frequency band of your router
Sometimes, you can't choose the 5GHz band or choose a "uncongested" channel. In this case, you can limit your router to send signals at 20MHz intervals, although this may reduce overall throughput, but will Give you a stronger signal.
10. Test the connection situation
There are many wireless monitoring tools that can measure the solutions we have given above. However, the most accurate tool is iPerf, which has a client on the laptop or PC you want to measure, and then has a server tool on the PC that connects directly to the router. After deploying the analyzer on both ends, you know your wireless speed.
My advice is to test the wireless speed of different locations on the router and client in your home or office. The hot map will point you to the best location.
