Hey guys I could really use some help with my internet issues. i can only get my network adapter to work for a few minutes before it starts screwing up and losing connection and completely disappearing from device manager. The only way to get it back is to turn off my computer and unplug the power, and turn it back on after a few minutes. After i restart the computer the adapter connects and internet works. but than drops again after a few minutes. am i looking at a bad NIC card?
