I have a Inspiron N7110 laptop problem I have never seen before! When connected to a power outlet the wireless connection is perfect, but when you unplug the power and work off the battery the you loose the wireless connection! Plug it back in and it is fine again. I have been fixing computers for 6 years and have never seen this before. But I see other people are having connection problems. See if you plug in in it connects. I have not found a answer for this yet, updated drivers, tried new battery, updated BIOS. Does anyone else have this problem of a answer!
