I am using an HP Pavilion desktop, not sure of exact model, etc. Initially saucy looked and worked great. It's my parents, and after two days of no issues, they started having more than a few.

The mostly use the internet to access email and videos. I believe Google Chrome was the only application they used. Then, the internet stopped working. Restarting didn't fix it, neither did turning the internet on and off. The computer went from lightening fast to inexplicably slow.

I've read some other posts about the internet not working, but none seemed applicable.

Any suggestions?
