SonicWall TZ150 drops all wireless connections
I have a TZ150 with firmware SonicOS Standard 3.1.0.15-95s. I am experiencing intermittent wireless connectivity. This morning I had 4 users successfully connected, and then all 4 were denied access for about 10 minutes and were not able to reconnect to the SSID.
I looked in the firewall logs and found these:
10/07/2008 08:33:31.416 - WLAN client null probing - 0.0.0.0 - 0.0.0.0 -
10/07/2008 08:33:01.272 - Packet dropped by wlan vpn traversal check - 172.16.31.196, 137, WLAN - Our Public IP, WAN -
10/07/2008 08:32:29.656 - WLAN client null probing - 0.0.0.0 - 0.0.0.0 -
These are repeated several times. Any ideas?

Here's a diagram of what hardware is out there.
**Internet** --> [Verizon Modem] ---> [SonicWall] --> Users connect wirelessly
The users are on a mix between Vista (32bit) and XP. They are connecting to the SonicWall's SSID using a preshared key. DHCP is handled at the SonicWall. Wireless users are on 172.16.31.0/24 and wired users are on 10.3.1.0/24.
They are all connected now, but I can't figure out what caused the wireless outage. The few wired users maintained their connection. I can only assume that it is related to the firewall entries I posted earlier. Those are the only error/warning messages I have.
The encryption mode is WPA -PSK.
