Pentium IV with Windows XP Pro SP2.
Antivirus AVG now, before CA Internet Suite.
Wired to a Wireless LYNKSYS adapter.
The computer works perfect if I do not use Internet.
It has been working perfect for about 6 months.
Immediately I press Internet Explorer works with the fast speed provided
by Cable Internet. After 2 or 3 minutes, the connection dies (95%) or the mouse freezes (5%).
What is strange is the fact that if I press VPN (that uses Internet, of course) the connection with that remains working, as should be.
So, the problem looks when I use Internet Explorer only, but I do not have a way to test a different option (only Internet or VPN).
I ran many different AV and they do not show any virus or thread.
Please help me with possible causes to check.
Thank you,
