2150CDN Wireless Issues

2150cdn with wireless adapter installed, running for 4 years with no issues. Had to set it up initially with a static IP, as Auto IP did not seem to work for me, My troubles started after a network change caused my 192.168,x,x based network to change to a 10.0.x.x network. I set up the new IP address and got it printing again. (10.0.0.16). While I had it connected via USB, I downloaded and ran the firmware update 201312051046 ,A05. This wiped out my wireless settings, I reentered via the panel and then via USB using the easy navigator software that came with the printer, but to no avail.

Any suggestions? I cant find the old firmware online anywhere, as my first thought was to back up to the original firmware version. Is there a known issue with the new firmware update and the wireless adapter?
