PLEASE HELP! major wifi problems!!!!!

i have no idea why this is happening, but every time i try to connect to my wifi at home it says "failed to associate with the network" ... when i first turned on this phone a couple days ago, it connected immediately and it is a saved network of mine, then i noticed a day or so later that it wasn't connected and always gives me this message... when my phone battery died and i turned it back on, it connected to the wifi again and again disconnected .. i am very frustrated!!! computers, ipad, and iphone 3 and 4 have had no problems connecting to the wifi ... i have tried to connect manually and it makes no difference .... can anybody help??? :(

Did you delete the network from your phones saved network? Battery pull? Security wipe? Give it a go.

yes i tried deleting it as a saved network but still no... i tried taking out the battery and sim card and nothing :confused:
whats a security wipe?

it's wiping your bb to delete all user setting..
don't forget to backup your data.
