''Network Cable Unplugged'' problem on Lin...

Hi,

Recently I've just bought a new AG241 Linksys ADSL2 gateway because I've decided to use ADSL for my internet connection.

Before that I was using wireless broadband and a D-Link DI-704P router.

The setup went well, and the internet connection is superb now, until I realised this problem.

I have a 4 PC LAN in my house. The thing is, when I use the old D Link router, all 4 of them are connected to the LAN succesfully. Now when I use the Linksys router, 1 of them got a ''network cable unplugged'' problem. At first I thought it's a cable faulty. But when I reverted back to the old router, it works fine.

How come a same cable is treated differently by 2 different routers? Please help and pardon my English ^^
