My internet connection works, but only for awhile. It randomly stops working at one point, but usually within 20 minutes it's over, so not completely random. After a reboot it works again for awhile... The computer model is an Acer Aspire 8930G, it's my parents laptop they just bought it (terrible choice, but oh well).
Is this a hardware problem you think or are there any test to run for the connection or port?
