my wife has a 3g, which is currently jb with spirit and for some reason I discovered last night that it will not connect to my home wifi, I tried it a million times. My wife claims it was that way even before I did the jb. Also it says that the MyWi is working but it is not noone can see it from any other computer.
the funny thing is that even though I cannot connect to my home wifi, I can connect to the wifi provided from my iphone when I have the MyWi turned on on my phone.
