Hi Megabuff,

Have you got the computers on your network as individual static IP addresses?

I hope this helps!

If you goto each pc then from a cmd prompt type


ipconfig /all


look for the ip 192.168.1.* you should find 2 with the same last number change one

IP4 address changes from automatic

Guys i found the problem to be the setting changed from "automatically obtain IP address" to "use the following IP address"

Put it back to auto and its all good, how ever on 2 laptops the setting keeps changing back to manual and i have to reset it again and again. like every day,

any idea what would cause this please?

Megabuff. Who is your internet provider?. Are you using WiFi to connect the laptops to the modem & if so what brand is your modem. Also are you using the NBN, cable or mobile broadband?.
