Internet Cuts out on all Browsers

Specs: Windows Vista
Hey, I'm not the one with the problem but as the subject says my friend has his internet cut out on him across all browsers. It doesn't cut out his AIM or any of his messengers, and he's tried just about everything to get it working again.

He uses Firefox for the most part but says that when he opens Internet Explorer that he gets the same kind of messages. We know it's not a problem with the fire walls, as they have been turned off with no success. He's tried a roll back with Windows Vista, but it only goes back a couple of months and this has been happening for far longer than that. It used to cut out every night at midnight, but recently it's been doing this during the day and it's been doing it at earlier times at night such as 11pm and 10pm.

He's tried power cycling the router, turning the computer off and back on, unplugging and replugging the ethernet cable (which sometimes allows him to stay on for longer if it's been unplugged all day), he tried resetting the local area connection but that never does anything. The only reason he hasn't tried uninstalling and reinstalling Firefox is because it happens across all of his web browsers.

If anyone could help that'd be greatly appreciated!

Error message are very useful in troubleshooting an issue. Unfortunately, you didn't include any. May I suggest you get your friend to write any/all error messages down and give them to you so you can post them here.

The heading for your post is: "Internet Cuts out on all Browsers" which makes it sound as if the problem is in, 'cuts in and out'. Is this the case, or has it cut out completely and won't come back?

If it's gone completely, check the DNS address on the PC's as that sounds like they're not getting proper DNS resolution.

He just gets the typical "Page Cannot Be Displayed" messages. There are no special error messages that would help reference what might be wrong unfortunately.

The Internet does cut in and out, but it's normally -hours- before it comes back if it comes back at all that day. Like, for example, right now it's working fine but he's not done anything special. I expect in a couple of hours it'll stop working again with no apparently rhyme or reason. And as I said before, it's not the entire internet it's just using browsers. Like AIM and MSN still work but he can't surf the web.

Also how would one check the DNS address? He uses Windows Vista.

It sure sounds like the DNS ( Domain Name Server) that he connects to is causing the problem. This is usually supplied by his ISP and it is his ISP that needs to address the issue.
Open Commandprompt and enter "ipconfig"

What is the DNS data ? It is possible to select a different DNS server but I don't know whether there are geographic restrictions or such to take into account

Tell your friend, the next time his browsing stops, to try pinging computers within the LAN to ascertain whether or not LAN connectivity still exists.

If it does, then the most likely problem is either DNS or the router itself is malfunctioning.
