Hi,
After checking for viruses, malware, etc., that cables and the netword card are securely connected, I still have the same problem - I can use the Internet for about an hour without problems afeter statup but then I become disconnected and I must restart the PC, to connect to the Internet again.
I also asked my ISP (Magnet) for their help and after they made several checks, they advised me to reinstall Windows XP.
So, before I do that, I just wanted to check if there is anything else I shoud be trying.
Thanks
