I am having trouble connecting to my home wifi network. When I first switch the iPad on it is fine, but then it disconnects itself and keeps prompting me for the password. When I enter it, it just says 'cannot join network' and asks for the password again. I know the wireless network is fine because my husband is sitting next to me using the laptop, and I know the password is right because I have had the same one for years. This has started since I jailbroke my iPad. Could that be something to do with it? Any suggestions?
