I have a Dell Inspiron 1720 running Windows 7. Wireless adaptor is an intel Pro 3945ABG The wireless adapter keeps switching itself off. This happens regularly - every 10 minutes - and I have to troubleshoot to reset the wireless adaptor. I have disabled the power setting that allows the computer to switch wireless off to save power and I have (I think) reinstalled the right drivers. The inspiron used to have a reset wireless switch on the left hand side, but this broke off almost immediately. Could it have worked itself into a problematic position and be causing the problem or is it another issue? Grateful for any help.
