Loosing Browsing Ability

i am on my daughter's computer, with RR broadband connection, and after browsing for awhile she gets the blank page and has to shutdown and reboot and it is alright.

I have ran spybot, adaware, housecall and stinger. Usually I run all of these and it is ok for awhile but comes back. What to do.

 

Is the computer connected directly to the cable modem? or are you using a router?
Do the cable modem lights still show that its is online when you can't surf?

When you lose the ability to surf, open a cmd window. Type "ipconfig /all", what does it say for your ip address and DNS servers? now type "ping google.com", what are the results? Now type "ping 216.239.39.99", what are the results here?

Are you using IE? If yes, check in the internet options: tools->internet_options->connections->LAN_settings, is the box for "automaticaly detect settings" checked? If so, uncheck it. That "feature" can sometimes cause the symptoms you are seeing...

 

m_town-I am now back home, which is 60 miles from my daughter's, so I will copy this info down and have to reply later.

I am going to call her and check out the last one as that is about all she will be able to handle with her limited knowledge of computers.

Thanks for the reply.
