WAX620 upgrade to 11.8.0.10 reset vlan

Last night I upgraded the firmware on my WAX620 from 10.8.13.2 to 11.8.0.10. Everything went fine except for one thing, the main SSID was configured to use vlan111 and this upgrade process reset it to use vlan1. Since my network was not configured to use vlan1, all traffic was blocked causing it to appear as though the upgrade failed.

To fix, I brought up vlan1 on the interface so it could reach the internet and more importantly Insight. Next, I logged into Insight and changed the configuration to use vlan111 as it was originally configured.

Hopefully this is just a one-off issue. Wanted to report it in case someone else runs into it.
