Hi

we recently bought and installed a Time Capsule 3TB, and it worked great for a month.  The wi-fi covered the whole house.  As of yesterday, we can only get the wi-fi signal when we are in same room as the Time Capsule!  There are ZERO BARS anywhere else in the house.

 

Help!  What could have happened?  what can we do?

 

Thank you

    Power off every device on the entire network...in any order that you want

    Wait a few minutes

    Power up the modem first and let it run a full minute by itself

    Power up the Time Capsule next the same way

    Keep powering up devices one at a time the same way

    Check the network

    Be prepared to change that channel again since other networks around you are constantly changing channels. So, what may be a good channel today might not be a good channel tomorrow. Too many wireless networks....not enough channels to support them.

    But it also shows the auto channel selection doesn't actually work properly as it is supposed to avoid this situation.. so if you keep to one channel it is not worse than auto channels not working. Plus you might scare off some other wireless routers when they test channel 11 and find something already using it.

    "Automatic" has always worked well for me, but I cannot explain why. Maybe it actually works for me.

     

    I don't check the router that often, but it does seem to always be on a different channel. One day it might 3, another 9, another 6 another 11. I just leave it alone. 

     

    But, I do understand that manual channels does work better for some users....and would not suggest that a user who is having success with a manual method should switch to Automatic.

    The symptoms that you describe match up closely with the characteristics of wireless interference problems.

     

    Read through this Apple support document for information on the causes of interference and some possible fixes.
