With the boom in streaming online content, and the majority of devices using WiFi it is essential to get the best performance possible out of your wireless network. One of the most annoying 1st-world problems is buffering or downgraded quality when you are streaming.
Many factors come into play with the WiFi speed, first of all, the actual speed of your internet, then the capabilities of the router itself. Some high-end routers like the D-Link DIR-895L are capable of delivering a theoretical 5.3 Gbps, which is faster than regular ethernet. Unfortunately achieving the speeds is unlikely as other factors come into play.
Distance from your router, obstacle in the way, and interference from other routers all affect the performance.
For users such as myself, in a large old house with thick walls, the speed will degrade very quickly, so it is often needed to have multiple routers in your home. This comes with its own set of issues, if you run everything using the same SSID, then devices can get confused about which router to access, and you need to carefully think about your Wifi network to make it work. With the advent of WiFi Mesh routers this issue eliminated, but if you don’t want to invest in a new technology choosing the correct channels for your WiFi is very important.
If you are buying new equipment, I would be inclined to ditch the super-fast single router option and go for a mesh network such as TP-Link Deco, Linksys Velop, Netgear Orbi or Ubiquiti Amplifi. Though this is dependant on the setting, in a small flat you may be better off with the fastest single router you can afford.
WiFi networks work on channels, and channels cross over each other if you have two routers connecting to channels close to each other than using the same SSID will be problematic. The routers themselves will theoretically work at reduced capacity too, as there is interference in the way.
Ideally, you will choose two networks on the opposite end of the spectrum, and I personally only use the same SSID on the 5GHz network which has far more channels.
If you want to optimise your network, I Wifi scanner will help, you can select the least congested channels and make sure there is no crossover with your routers.
WiFi Analyzer will help you get a visual representation of your network’s channel as well as the best available channel you can use to get the optimum speed. When you launch the app, you will see a graphical representation of all the networks available in the area. The higher the graph, the stronger is the connection. However, this is just a visual representation, to know which channel you should tap on the eye icon and select channel rating. There you will see the list of all the channels with star ratings attached to it.
This is a good option as it has one of the best user interfaces. You can see all the networks around you in a graph mode or rating mode, whichever meets your needs.
This is more to manage your Wifi on the device, but it is a worthy option, you can still scan the network and find out the signal strength. What I like about it is that if you use multiple SSID, you can have it automatically connect to the strongest option
Since iOS does not allow apps to access its WiFi connection chip, there’s only a limited amount of functions that a WiFi analyser app can perform. The best app on iPhone to analyse your WiFi connection is the Network Analyzer.
