I reconfigured my wireless router, left SSID same, changed gateway address. Vista would say it had 'limited connectivity' (e.g. none) when I tried to reconnect to the router. I disconnected, deleted the wireless profile using the Network and Sharing Center>Manage Network Connections, then reconnected and had same problem.

I disconnected, deleted it again, and restarted the computer and had the same problem. Looking at ipconfig /all, DHCP had not been successful, but it had the old gateway address and a subnet I have never used.

Vista seems to be caching wireless profile info somewhere and refuses to purge it when you delete the profile. Does anyone know how to really delete a wireless profile in Vista?

I have an overwhelming impulse to rant on Vista and Redmond right now, but I will refrain.

Thanks.

Try changing the SSID, that should work.

Sorry, should have also mentioned that once you've changed the SSID name, done a 
reboot, do the following:

1. In the Network and Sharing Center, under Tasks on the left side, click Manage 
wireless networks to bring up the Manage Wireless Networks window. 

2. Right-click the old SSID (network name) that displays in the list and choose Properties 
from the menu. 

3. Click to clear the "Connect to a more preferred network if available" checkbox.

If you're still having problems after than, you can also try using the Netsh command 
and block networks by specifically adding the wireless network to the list of denied 
networks.

I didn't change the SSID because I didn't want to go around to the people who are sharing my wireless and change their connection preferences. I wanted it to appear seemless for them. Pretty much the only thing that changed was the gateway IP because I have a router where you can divide your wireless into secure and unsecure segments with separate SSIDs and gateway IPs. I hadn't been using it, but I just set it up. The transition appears to have worked fine on XP machines, bad bad Vista >:( I am sure there is some command you can type into the shell or registry keys you can delete to purge whatever remains. But since Vista is still relatively new, I haven't been able to find anything with Google searches. Any other ideas?

Have you tried:

sfc /purgecache

Consult the manufacturer's information to see if that somewhat unique feature of 
separate networks is accomplished thru some programming within the router that is 
not Vista compatible.

Could you post the make and model of router?

@Deb, I'll try your suggestion tonight. sfc /purgecache

@Dan It is a Linksys WRT-54GL with DD-WRT RC7 build 9379 firmware. It should be compatible with anything that correctly implements 802.11g as I believe it is only time multiplexing the wireless interface to create second virtual interface.

I suspect Vista because I read (which I can't find again right now) that Vista retains certain settings even when you remove items in the GUI. I have had an almost identical problem removing and re-adding printers.

Maybe I will try changing the SSID tonight to see if that works. I wish I had a fresh Vista machine to try out that has never seen this AP. Of course I'm glad I have no more than 1 Vista machine in my fleet.

Could be a conflict between Vista and your non-standard firmware.

You could narrow it down by reflashing to the current Linky firmware for that unit 
and then test for the problem....

I'd get rid of Vista before I'd go back to that clunky Linksys firmware. DD-WRT rocks! And DD-WRT is based on OpenWRT, which is based on Linux. As far as proven standards go, it should be as close as you can get to enterprise grade Cisco networking gear without spending $500.

But Vista is doing fine connecting to the new secure wireless segment (the one with the new SSID and new gateway address). It only won't connect to the insecure segment (that has the same old SSID but a new gateway address.)

I searched more and stumbled on what I needed. Turns out I hadn't quite finished setting up the virtual interface. http://www.wi-fiplanet.com/tutorials/article.php/10724_3714521_2

I still think my assumption about Vista being at fault was reasonable since the old and erroneous DHCP entry survived a reboot. But for a first I can't blame Vista for my problem, it was me!

Thanks Deb and Dan for the moral support!
