Win7 ofice AD Domain machine on home WLAN
I have two office Win7 Pro 32bit laptops (member of the office Win-Server2003 AD Domain) "Dell-A" and "Dell-B"
Home WLAN was recently changed from WEP (hidden SSID) to WPA-PSK/TKIP (broadcast SSID)
Both Win-7 machines have worked perfectly on the home WLAN using DHCP under the WEP setup for a year.
Vista machines, Logitech Squeezbox etc connect to home WLAN (WEP and now WPA) with no issues.
Dell-A was the first to be connected to the new home WLAN WPA setup.
Everything worked fine for around 40 hours then internet connection stopped yesterday afternoon (nobody in the house so it wasn't a user action). After I got nowhere thrashing around with reboots, I tried to connect Dell-B: not even the 40 hours grace period - no connection.
Here are the symptoms now shown by both machines:
Manually configure IPv4 to something in the WLAN subnet...
Network center shows the WLAN as home network (clickable blue) with an internet connection.
I get decent pings to anything on the WLAN and to the external world e.g. ping 74.125.43.105 (but not ping Google since I have no DNS). Web browsers happily connect to a typed IP (but not URLs since I have no DNS).
Switching IPv4 to DHCP...
Network center shows the WLAN as unidentified network (un-clickable black) without internet connection
IPv4 switches to the dreaded 169.254.156.189
No pings, no browsing, no nothing.
Switch back to manual IPv4 ...it works again
(i.e. SSID/PSK/Channel etc are all correct)
Throughout all this, I continue to listen to jazz radio from the internet on the Squeezebox whilst typing this into the forum on my Vista machine --- the WLAN is working fine!
I suspect something to do with these two machines belonging to the office Domain.
Thanks for your thoughts.
