No Internet when 1 computer on network
Posted on 2007-10-18
a client has a network in their house. dlink router, bought 6 months ago. they have 2 computers connected wirelessly, 1 desktop called "gaming", one laptop called "ernie". the gaming computer has a printer connected to it and shared. in the office, i replaced an older computer with another used but newer, which will be called "office". the internet is in the country, where dsl/cable is not availble. the internet is wireless, with a fixed ip address, gateway, etc. these values are entered in the router, which connects to the WAN radio on top of the house. with the network setup successfully for months now, both gaming and ernie can go on the internet, share printers, etc.
this is where the fun stopped. when i switched the office computer to the new one (xp sp2), the internet connecton would not work. all 3 computers could continue to see each other, share files, share printers, but none of the 3 could connect to the internet. when i plugged the radio cable straight into the computer (instead of teh router), and put in the fixed values, it also could not go onto the internet. yet when that office computer was not on the network, the internet worked fine for the gaming and ernie computers.
i am stumped. what should i look at first? is it a software issue with the office system? hardware? should i plug another network card into the pci slot and try that one? (currently onboard). is it a lspfix issue? where to start?
