VGN-AR31M / Belkin F5D7632-4 Router
Vista Home Premium / Norton 360
Intel(R) PRO/Wireless 3945ABG Network Connection (10.6.0.29)
Just wondering if anyone has a similar problem, or any ideas as to how I may resolve this intermitent connectivity.
Had the VGN for a while now, all working fine with the Belkin until about a month ago. The Wireless connectivity now seems to be fine for a short time - showing [Access: Local and Internet], but then sporadically changes to [Access: Limited connectivity]. The time between working fine and local only varies from about a minute to half an hour. It does not reconnect to the internet on its own, but if you disconnect>reconnect it works fine for a while again.
No settings have been changed at all on the router or by me on the VGN-AR31M. I've been through all the usual power cycling of the router and laptop, Windows network diagnostics etc. Signal strength is always good, I've got another Vaio/XP and an HP/XP laptop that continue to work fine.
I've read a lot about Vista flakiness generally, but I'm guessing due to the suddenness of the issue it may have been related to a Windows update. Without going through the usual uninstallation of tens of updates only to find it wasn't any of them, has anyone got any suggestions?
