I'm running a USR 9106 ADSL router, I've configured it to allow DHCP on a subnet of 255.255.255.0 in IP range, 192.168.1.2 - 192.168.1. 100 only, recently a few people have come over to my house with their laptops and they have been unable to connect to my router they get limited connectivity, putting the machine on subnet 255.255.0.0 and they cannot ping 192.168.1.1 - the gateway / router. IPconfig release / renew does nothing. Each time this happens the person is running Vista. The Vista machines can see my router but they cannot get an IP - why is this? I've tried to manually assign an IP address and DNS, but this hasn't worked either. I have not configured my router to park machines on subnet of 255.255.0.0 if there is a problem, so I've no idea where the machines are getting this from - additionally the IP address is NOT within the defined IP address range.
I've recently changed jobs and my new work laptop run XP and I've not had a problem connecting to my router.
Additionaly I've recently upgraded my 3 home laptop / desktop machines with Win 7 - fresh builds not upgrades - however the problem has only started since moving to Win 7. I've setup a 'Homegroup' for my machines as well and they never have a problem connecting. My sister brought her new 'pink' HP netbook over to show me, which runs Win 7, she had no problem with my router.
Can anyone offer some advice??
Has Win 7 got anything to do with the problem??
