I have 2 New Computer with WinXP SP3 [Connected Via Ethernet Cable] and a Laptop with WinXP [No Service Pack] [Connected Via Ethernet Cable].
Now LAN works beautifully. No problem with that.
The Problem starts ONLY when I connect the LAPTOP to the Router the internet stops working. Without THIS laptop connected, The internet works fine, between all the computers.....[added 2 more comp just to test and it works fine].
Once the Internet stops working I reset the router, the internet starts working for 5 mins and stops. BUT THE LAN CONTINUES TO WORK THROUGHOUT !
The is what I have tried so far.
1) Re-installed The OS of the LAPTOP
2) Removed the 2 Computers and connect only the Laptop to the router. And Internet works flawlessly. So problem can't be with the Laptop Network card.
3) Got my friends Router [same model Version 6] still the same problem.
I used to use this LAPTOP with the same router and a old comp without any problem. The problem started when I got the 2 new systems.
The problem occurs even when I connect the laptop with a wireless Network card.
This has got to point that I am obsessed as to why it isn't working !!!!
All symptoms looks like a conflict but what that conflict could be ?
ANY HELP appreciated... so that I can sleep again !
