iPad 2 won't connect to a certain wi-fi

[RH5]

My iPad 2 will not connect to my wi-fi at home but it will connect at my school, friends houses. All my other devices connect to my wifi at home with ease (iPhone, Macbook, iMac). Is there anything wrong. I click my wi-fi on the iPad and type in the password, and all it does is shows a rotating circle beside my wifi.

I had similar trouble with one location and switching the WiFi channel to 11 instead of 6 solved it. Too many nearby radios on the same channel, I reckon. Most seem to default to 6 out of the box. By viewing the channel spectrum with INssider I found my router was actually jumping between channels 6 and 2 every few seconds.

Channels 3, 6, and 11 are 'special' in that they have less overlap with adjacent channel allocations, so that means less chance of adjacent channel interference.
