I bought my computer in October, everything was fine, but few months ago I started to have issues with my internet controller.
Every hour or two connection drops for approx. 1 minute. I can still visit (and ping with no packet loss whatsoever) few sites (google.com, youtube.com for instance). Skype seems to be working too. Not a problem if I just browse the Web, but if I play online and this happens it's really frustrating.
I have two Internet cables and I have this issue with both of them, however everything seems to be fine on the second PC. Reinstalling drivers and resetting BIOS didn't help and I'm pretty sure it's a hardware issue.
