Vista - WiFi Signal Strength: No Signal

Since installing Beta 5456 the signal strength icon has started claiming "No
Signal" even though I have successfully setup a wireless connection and
connected OK to the Internet. If I disconnect the network, the WiFi
connection appears in the list and the signal strength is shown as excellent
(5 bars). If I then select the connection and click the "Connect" button,
Vista shows the acquiring IP address dialog; then says I am connected but
with "limited connectivity". At this point, the signal strength is showing
as "No Signal" again. Despite this, I have a good connection to the Internet
(confirmed by the network map).

Is this a known problem / bug? It was working OK in the public Beta 2.

The happened to me with the prior release (all I can get). Happened after
an automatic update to my Intel 2915abg driver. I rolled back and it fixed
it.
