Some routers can have troubles with routing the data correctly when you are two on the same network even though it should work - sometimes it works if you setup your network with static IP's for all devices instead of randomly assigned.
If that doesn't work there might be another solution - now you don't mention what router you use but if updating your router with the latest firmware doesn't work you might want to change the entire firmware. Lots of routers are fitted with rubbish firmware and this have made custom firmwares appear. Personally I've thrown away the horrible firmware on my D-Link Dir-615d router and replaced it with firmware from http://www.dd-wrt.com - now it's perfect even though 615d is a cheap router.
Remember: flashing firmware on your router can ruin it if something goes wrong, but if you are going to buy a new one anyway you got nothing to loose 🙂
Thanks for the response. I have tried assigning static ports to both of our PC's, are you suggesting assigning one to every device on the network?
I was hoping using some type of open/aftermarket firmware would be the solution but my router isn't supported by any firmware I can find. It is a Medialink 300N.
Thanks again.
