IE loses internet connection

[windozuser]

I am having problems with IE losing the internet connection. This means that
after displaying a web page and then waiting about 10-15 minutes, I am unable
to browse to any web site. I get the error "unable to load web page".

However, I am able to open a DOS window and ping web sites, I can also send
and receive email from Outlook Express.

I have tried switching browsers, scanning for viruses and even checked for
winsock corruption but nothing seems to work.

When this does happen I have a Cisco VPN client that allows me to log into
my network at work. After I establish the connection and then disconnect from
the VPN, I can then browse the internet without issues.

My setup is XP Pro with latest service pack and Linksys wireless hardware.

Any ideas?

Hi
Check the running processes, make sure that the VPN client is Not running
when it is Not needed.

Jack,

Yes, I've checked and the VPN process is not running. This is so frustrating
as I have a similar configuration on my laptop and I don't lose the browser
connection. I'm seriously thinking of reinstalling XP again, on the desktop.

Any other ideas?

Thanks,

Carl

Hi
Try to check Cisco's support. Might be that they are aware of such problem.

I have removed the Cisco VPN software and still have the problem.

I turn on the PC, after about 4-9 minutes of web surfing the browser loses
internet connectivity. However, I can open a DOS window in ping
www.microsoft.com or www.yahoo.com. I can also send/receive email from
Outlook Express.

I have tried flushing the DNS, using a static IP address, but nothing seems
to work. This problem occurs across browsers (FireFox, Chrome, IE).

I know I can get out to the internet because I can ping, but the browsers
just lose connectivity. The only solution is reboot..browse for 5-9
minutes..reboot..browse for 5-9 minutes..reboot.

I have scanned for viruses and such but none are on the system.

Any ideas?

Hi
Short of reinstalling the OS try this,
