Internet connection stops working after half an hour

I am having problems with my internet connection. When I first start my computer and use the internet it is perfectly fine and then after about a half an hour it will have trouble connecting to the next pages where I am trying to go. After half an hour it stops working  and then works again if I restart my computer. I am not sure if it is my internet or a virus. So basically it works for a half hour then it stops connecting to any websites or pages. I use ethernet. If you have any input on this problem that would be great.

A complete virus scan (and spyware scan) with up to date virus list can't hurt.  Please describe how you connect to the Internet: dial-up, DSL, cable; router, directly connected to broadband, using university campus high speed port; ISP name, company or campus connection, etc., etc., etc.

Also, when it stops processing, go to the task bar and right click.  Choose task manager.  Do you see your browser listed?  Does it say NOT RESPONDING or RUNNING?

Hi, I do have norton anti virus and I did do a check, it said I do not have any viruses. I connect to the internet with university campus connection ethernet. I did the task bar check and it said that the internet was running. Also sometimes if I click the refresh button a few times the page will open up(sometimes). It is really weird I have half an hour to an hour of internet time and then after it just says cannot find server when I am trying to go to the next page. Even my aol instant messenger continues to work. If you have any more insight that would be great. Thank you!
On IE, go to tools, internet options, connections tab, LAN settings.
Do you have any check marks on that panel, if so what are they and is there any text in those text boxes?

Does this happen anytime day or night?  Or just certain times of the day?

Also try going to tools, internet options and 'delete files' under Temporary files.  See if performance improves.
OK under LAN settings one box was check marked and it said use a proxy server for your LAN. This problem happens anytime day or night it does not matter. I will also try the deleting files. get back to me, thanks
See if you can reach the Internet without the proxy.  If you can't try adding this setting: Tools, Internet Options, General, Temporary Files, Settings, "Every Visit to Page".  See if this helps.  I have a feeling the problem is with the proxy server, but since only your campus support has access to it, you may have to start working through them to determine what the problem is.  You may also be loosing your connection to that server.  If these other settings don't work, you may want to download a ping tool to set up a continuous ping to your proxy server (assuming it responds in the first place).  You'd be looking for any drops.

My other theory is that you are setup on PPPoE and that can cause your IP to change every hour or so.  Check your setup documents to see if it mentions PPPoE anywhere.  Usually closing the browser and opening it back up again will bring up your pages... but that's a pain.
I did put the settings on every visit to page.....when it starts having trouble it seems like i only have to push refresh 1 or 2 times where before i would press it like 5 or 6 times...if that means anything at all.... but then it gets to the point after a few more minutes where refresh doesnt do anything anymore so it doesnt really make a difference......  also what is a ping tool....   any more advice?? thanks

I was having pretty much the same problem. I was browsing internet and randomly my internet would just stop working. Either reset of the computer or disable and then enable connection would help.

So try to manually set DNS server addresses.
Go to Local Area Connection, right click Properties, Internet Protocol Tcp/IP, Properties and set DNS server of your ISP.

To find out your ISP DNS go to START/RUN then type CMD
then

ipconfig /all

and check DNS servers.

I fixed my problem that way. I hope it helps.
