Network Intermittently Stops Working
I have this intermittent fault on my Vista Ultimate laptop with an Intel
Pro/Wireless 3945ABG Connection. About once per day, with seemingly no trigger, my network connection will stop working. To be more precise, the network still registers as connected but i can access no network traffic, either internet or router settings. Vista reports that my connection is now "Local Only". This can only be corrected by a system restart. Attempting to view available networks to connect to fails (Windows can find none, even though right now (as I type this) I am in range of 15 networks. Attempting to 'Diagnose and Repair', or trying to disable and re-enable the adapter causes the Network Center to hang. If I reboot, it works again for another period, usually around 9 to 12 hours. If I've started the Diagnose and Repair, Windows cannot reboot on its own, and I must push the power button and reboot cold. I have tried -different networks -(re)installing the latest drivers from Intel and my manufacturer (same version available from both parties) -different power settings (I'm currently back to the "high performance" mode) -Complete destructive system restoration by booting to the restore DVD and destroying the partition and reinstalling Windows completely.

Network Intermittently Stops Working
I think you may be on to something. Something I haven't checked (although I
should have, shame on me) is if I have a valid IP address when this disconnect happens. I bet it's likely that this happens at these intervals because that's when my DHCP lease expires. Right now my lease time is set to 1 day. It's work experimenting with. Maybe, for some reason, Vista cannot renegotiate when the lease expires. I'm going to try adjusting the lease time to try to reproduce the issue, as well as using a static IP, and I will post back my results. Thanks for the advise and link, Robert L! "Robert L.

Network Intermittently Stops Working
Update:
Setting a static IP4 IP address, and disabling IP6, still resulted in the loss of connectivity and requiring a restart (i.e. -- no change). Also tried disabling the "Broadcast Flag" via registry edit, no effect (so I put it back the way it was). Great link and suggestions, but no avail yet. Any other ideas?

Network Intermittently Stops Working
On the Internet Connectivity Evaluation Tool, here are the results...
Basic Connectivity... Supported (of course) \Network Address Translater Type... Not Supported Traffic Congestion Test... Supported TCP High Performance Test...Supported UPnP Support Test... Not Supported Multiple Simultaneous Connections... Supported I looked throughout my router settings (Linksys WRT64GS) and UPnP is enabled, so I'm not sure why the test failed for that. The other 'not supported' feature, NAT, has no options to configure in my router. However, per my xbox (on the same wireless network), I have an 'open' NAT. "Robert L.

Update: Setting a static IP4 IP address, and disabling IP6, still resulted in the loss of connectivity and requiring a restart (i.e. -- no change). Also tried disabling the "Broadcast Flag" via registry edit, no effect (so I put it back the way it was). Great link and suggestions, but no avail yet. Any other ideas? "SKeene" wrote: I think you may be on to something. Something I haven't checked (although I should have, shame on me) is if I have a valid IP address when this disconnect happens. I bet it's likely that this happens at these intervals because that's when my DHCP lease expires. Right now my lease time is set to 1 day. It's work experimenting with. Maybe, for some reason, Vista cannot renegotiate when the lease expires. I'm going to try adjusting the lease time to try to reproduce the issue, as well as using a static IP, and I will post back my results. Thanks for the advise and link, Robert L! "Robert L.

I have this intermittent fault on my Vista Ultimate laptop with an Intel Pro/Wireless 3945ABG Connection. About once per day, with seemingly no trigger, my network connection will stop working. To be more precise, the network still registers as connected but i can access no network traffic, either internet or router settings. Vista reports that my connection is now "Local Only". This can only be corrected by a system restart. Attempting to view available networks to connect to fails (Windows can find none, even though right now (as I type this) I am in range of 15 networks. Attempting to 'Diagnose and Repair', or trying to disable and re-enable the adapter causes the Network Center to hang. If I reboot, it works again for another period, usually around 9 to 12 hours. If I've started the Diagnose and Repair, Windows cannot reboot on its own, and I must push the power button and reboot cold. I have tried -different networks -(re)installing the latest drivers from Intel and my manufacturer (same version available from both parties) -different power settings (I'm currently back to the "high performance" mode) -Complete destructive system restoration by booting to the restore DVD and destroying the partition and reinstalling Windows completely.
