    If you have an Android phone, a really handy program that tests what channel surrounding Wi-Fi networks are on is called “Wifi Analyzer”. Free and easy to use.

    Hi, thanks for your excellent site!
    We have noticed a lot of wifi congestion at home too – so I think it’s time to change channels.
    I bought ‘wifi scanner’ for the laptop, and am about to start the process of cycling through my wifi channels to see what gives the best signal.
    I have a time capsule plugged into a netgear modem- how do I change the channel on the the time capsule (which is what I use for my wifi signal)?
    Do I need to change anything on my modem?- or just the time capsule….
    If I am unable to compare the best frequency from my iphone, does that matter? (Unfortunately apple has taken all those handy wifi checking apps off the iphone app site).
    Thanks for your help.

    I think you are confused about your number of channels. In the US there are 11 and in Australia there are 13.

    Information was helpful. Is it possible to have no connectivity at all with some channels? my router was set to use 11 but when i tried say 5, i was disconnected and was not able to connect back till the changes were reversed.

    Am staying with a relative who has broadband which is very weak as we are well away from the exchange.

    There are many routers in the area – all of our neighbours use channel 11. The modem also has ‘channel 11′ written on the bottom.

    I have been unable to access the router using the usual ‘admin/password’ info. I have, instead, plugged the modem into my Time Capsule and now it thinks it is on channel 1.

    I still feel I am missing something though and would like to ask if, regardless of my cunning manoeuvre, I have not completed my task and still need to chance the channel on the router?

    Nice piece by the way. Informative and easy to follow.

      Wel it’s gone and so has every other App that measures wifi strength! It seems Apple has disabled or banned the ability to measure wifi signal strength on the iPhone.

    Nice advise!! I should have found here before calling att, today. As I had a problem to connect to home wifi network to iphone and samsung, I was instructed by remote access the same thing by paying $50 despite of having u-verse box 3 days ago. I found the connection issue when my iphone failed to have Netflix.

    Great advice – worked perfectly, though I accessed the router a different way, I was able to tell it to “change the channel” and now I have full strength again. Sure appreciate your advice!

    This was very helpful. My wifi kept dropping intermittently all day long. I changed the channel it is working a lot better.
    Thanks for posting help like this.

    This did not help me. I’m running OS 10.9.5 and in ‘System Preferences’ it does not show the router address. It says ‘Configure IPv6′ AUTOMATICALLY. If I switch it to manually, I would have to type in a router address, and I do not have one.
