Channels, bandwidth and merging - How to easily optimise your Wi-Fi signal

A slow wireless connection - it's not fun but it can plague any of us. We can show you how to perform first-aid next time your home network suffers a bout of sluggishness. After reading this article you'll be ready to start tinkering around the inner workings of your router. Not with a soldering iron, but with a mouse.

We've all been in this scenario. You're connected to a router and the signal is strong, but the Internet is really slow. The signal looks fine, so physically moving the router probably won't do much. Buying a new router might, but that costs money, and getting a cheap one kind of defeats the purpose.

There are other options, however. Inside the router there are a number of things you can play around with in order to increase the transfer rate of the wireless signal of your device. We will describe how to make manual adjustments to the bandwidth of the channels and the strength of the signal. This article focuses on the 2.4GHz band, since you're more likely to have issues on that frequency than on 5GHz.

One of the easiest things you can do to boost the signal of your router is to change the channel it's on. Especially on 2.4GHz, this can lead to a marked improvement. The other wireless networks around you can cause interference in your network. Most routers will automatically select a channel for sending and receiving a wireless signal, but that doesn't mean it's the best one for your particular situation. Apparently it's still a challenge for companies to create a channel selector that's smart enough. Netgear alone had this feature in the WNDR3800, only to leave it off subsequent routers.
