    Great article, Ciprian! However, with the information you’ve provided here, Channel 1 would have been a better choice. This is because Channel 1 is one of the three non-overlapping channels (1, 6, 11) and as shown in your screenshots, the other networks running on Channel 1 have low RSSI values. We at MetaGeek also have prepared a guide to identifying interference that can be downloaded from http://www.metageek.net/support/faq/.

    We are also planning on our next mini-video being specifically about channel overlap, so stay tuned to our YouTube channel!

      The reason why I did not choose channel 1 is because there is always at least one network interference throughout the whole house on this channel. On channel 13, there is interference only in one area.

      So far… it seems to be working even better than before making this change.

    Thanks Ciprian! Saved me from breaking down and buying a dual-band router – I found a nice little niche at channel 8 amongst the 100ish networks competing for supremacy in my condo. 🙂

      You are welcome Patrick. I hope this helped and you are having a better experience with your wireless network.

    This was really informative Ciprian. Thank you for posting this I gain more knowledge on the matter. I have 4 security cameras and they are interfering with my router signal. I’ll try to implement what you wrote.

    Thanks Again,
    Manofsound

    The RSSI is negative number showing the dBm of signal. You should choose the channel with the highest number, which is the weakest. When you measure signal beside your own router, the RSSI is around -35 dBm. When you move away from tje router, the RSSI is reduced to -60dBm.

    there are numerous ways to improve your WiFi signal, but the final result depends heavily on your environment.

    some tips that may work:
    1. try amplifier — it can be expensive as specialized directional antenna, or cheap as a soda can.
    2. change channel settings — the 2.4Ghz WiFi(802.11 b/g/n) only has 3 non-overlapping channels, set your channel to one of 1/6/11 will help reduce the chance of overlapping channels.
    3. regularly scan your environment — in scan result, you will see how many networks are around you, and the signal strength, channels they running etc. Then you can avoid running a similar network, and find a relatively *clean* environment

    These tips sounds a bit *geeky*, but there are a lot of tools available to ease the processing. For example, WiFi Manager ( https://play.google.com/store/apps/details?id=com.wifi.manager&hl=en-us ), an Android App, is able to do the scanning, and show result in an intuitive graphic way.

    The lower the number, the stronger the signal when using inSsider. Not the higher the number as stated in the article.
