It continually notifies me that wifi is availiable. the network in my house comes up and I've typed in the password, it says it remembers it, I hit connect but nothing happens and then when I use the internet it uses 3g. My sister just got an iphone and was able to connect to our home wifi and I have no problems with it on my laptop. help anyone?? I'm a new droid user--I had dumbphone before!
