RE: [STN] Cable problems: some answers to your questions about my problem

Wed, 03 Jan 2001 11:00:50 -0800 

I can ping the external IP of the router from the client
I cannot ping to an external ip (www.microsoft.com) from the STN

but the whole setup worked fine for a while...

Ok so it could be two things.
1 a faulty network card connected to the cable modem. Which after DHCP goes
in a loop or has big problems with TCP/IP packets.
2 The routers NAT doesn't work anymore. (but then you should be able to ping
the external ip adress.

I think it has something to do with wiring or a faulty network card. You
said something about when you reboot it doesn't work, when does it work
again. After a few hours days?
