hi . i m also facing this type of problem , so i suggest you make the new connection or re establish the connection. check the cable also.
I have been using my desktop with not problem getting onto the internet using Netscape ISP. My hard drive died yesterday so I am using my laptop, but since switching to my laptop I am losing the connection after about 5 minutes. Then I get back on and it happens again after about the dame time. What can be happening? Thanks.
