I have a Dell dimension 2400 with a dial-up internet connection using one phone line. I was using the internet when I started to be unable to see any webpages. I checked with both firefox and IE, and both say that the server/website cannot be found. Another computer using the same connection but a different phone jack is works fine. I have had similar problems before, but disconnecting, and then connecting again would fix it, which hasn't worked this time. I am able to connect to the internet normally, but occasionally it will stop working in the middle of what i'm doing, and only after I have been using the internet for a little while. Then I have the problem with not being able to view any web pages and no programs being able to get a signal from the internet. When I disconnect and then reconnect it does not fix the problem, but when I disconnect, restart the computer, and then reconnect, it works again.
Any help on this would be greatly appreciated.
