I have an Acer-9300 with an internal wireless card. I connect to the internet server fine with a strong signal indicated but when I plug in my AC adapter it disconnects and shows no wireless signal available. I disconnect the AC adapter and it will re connect. Any suggestions on what to do will be appreciated. I am using an unsecured provider in a campground in Mazatlan.
