Hi Slade

have you checked for virus ? grin
spyware ? grin
downloaded something you shouldnt ? grin

no seriously, just typed into google "internet cuts out after 5 mins"

there was no real decent answers, but i found something about

ipconfig /renew

would be helpful if you told us your Operating System, Memory, Internet connection type, ie Dialup/DSL/Cable etc.

Im sure somebody might be able to help you.

Just lurking
