I have windows 7, on an hp dv7t notebook. I am having a problem where, periodically, my wireless will not work. The wifi button will be amber, and it will not turn blue.
The solution is usually to 'reset' the wlan through the trouble shooter. Then, it works. Sometimes, it says that the device manager has disabled it, and I have to enable it. Sometimes, nothing works and it will not work for several days. I have updated my drivers, no change.
