Ok. I don't know anything about Ubuntu but me and my husband have been tinkering with our windows 8 acer laptop. We managed to fully install Ubuntu 12.10 on a 64gb USB flash drive. Our problem right now is the wifi. It will detect networks and we can connect to wifi but the Internet stops working after a minute or so. Then we have to disconnect and reconnect again and the same thing happens. Internet is fine with a cable connected. Our wireless adapter is Qualcomm atheros ar5bwb222. Pls help.
