AXT-1800 Crashing Loop

My AXT-1800 (running 4.4.6) is constantly crashing and rebooting. I’m connecting in repeater mode. I’ve done some searching and found some prior support recommendations to try downgrading the WiFi firmware, which I have tried. Unfortunately, the symptoms have persisted. I have pulled my crash log, syslog, and kernel log in the hope that it may prove helpful, but I don’t seem to be able to upload them.
