lately my friends computer stopped being able to connect to the internet, he called his isp and they ran him threw a bunch of stuff that dident fix the problem. His computer shows that his network is not connected, i tired swapping out his card for a new one, then trying a new pci slot, then checking for viruses/spywear, and then bringing it over to my place to trying it on my network that i know works. and still the same problem dose anyone have an idea what the problem might be?

It could be a tcpip setting or even firewall setting if the driver for the nic are properly installed. When the cable is connected, is there a green light lit on the nic? Disable the firewall and see if you can connect. If not, go to the command prompt and type in ipconfig/all then post those results.

try pinging 127.0.0.1, also make sure that he doesn't have a static DNS entry, check all of his tcp/ip properties. The significant problems we have cannot be solved at the same level of thinking with which we created them.

i had disabled the firewall forgot to mention that, it shows that the nic drivers are proper. There is no green light/ any light activity on the back of any of the cards, ive tired: the Ip config reads as: primary dns suffix (blank) ip routing enabled (no) wins proxy enabled (no) media state (disconnected) the ping to 127.0.0.1 works, all his tcp/ip settings are set to auto it still seems like the computer thinks that there is no net plug coming into it

oh and node type is : broad cast

No green light means no connection or "link" and is verified by your ipconfig info. It either is the cable, router or dsl/cable modem that the cable is plugging into.
