Hi. I hope this is the right place to post, as I believe it is something to do with Windows Vista. These are the computers at my home: 1. Desktop - Windows XP Pro, Internet Gateway (connects to broadband), Linksys WUSB11 v2.8 2. Notebook - Windows XP Pro, Intel 2200BG 3. Notebook (Newcomer) - Windows Vista Home Premium, Intel 3945ABG All these while, the 1st and 2nd computers have been linked in an ad-hoc way, such that the notebook can use the internet. The newcomer came, and it has problems. After connecting to the existing network, the new notebook will be fine for a moment (Local & Internet for 1 min?, but variable time), then after a while, the Network and Sharing Centre will show that there is Limited Connectivity, with Windows Vista trying to 're-identify' the connection. I have tried by using manual IP addresses (as opposed to DHCP) but it doesnt help. The connection between 1 and 2 remains unaffected though. I have tried updating drivers to the newest, turn off power saving, remove WEP, turn of firewall etc., bring computers close to one another but doesn't help. Today, I tried to create an ad-hoc network, starting from 3. 1 then connects to 3. And voila! The connection for 3 is very very stable, no drops or anything. I experimented with this many times and found that it is reproducible, so not a random effect. If 1 were to initiate the network, the problem starts again. Is there a way to go around this? I want everything to be as 'magical' as possible - wouldn't want the user 3 interrupting the 'entire network' just so that 3 could work! Thanks!!!
