By cutting out i mean that some guy said he had fixed the problem...when he went home my friend was on the net ok. However when he switches off the computer and tries to get on the net the next day....the inernet connection has gone again.
They have called this guy out a few times and its happened everytime.
Need more info dude, What errors if any, How do you connect to the internet? DSL, Dial-up, cable modem, If it works until you turn your PC off then it's losing its settings in software.
I have been having a similar problem, i connect to the net using dial-up and it all happens at random( could be in the first 10mins or could last 1 hour).
All of a sudden i try to access a new page and get an error saying "page can not be found." i check the taskbar and the internet icon is still there, i pick up my phone and i get a dial tone.
I have to manually disconnect my computer from the net and dial again to re-connect. I have rung my ISP's customer service number and all they could say was my password was corrupted, they gave me a new password but i am still having the problem.
Turn off the computer. Pull out the cable from the back. Turn the computer on, wait for it to fully boot-up, and once it's idle, stick the cable back in.
