CPE210 stops working/ looses configuration
I have a pair of CPE210s that are about 2 months old and operating in AP/Client mode. The AP stopped working a few weeks ago and I assumed it lost its configuration. I reconfigured it and it worked for a few weeks. Now it has failed again twice in the last 24 hours. I reconfigured it again yesterday and it worked for several hours. Now it is dead again.
It shows only the power and LAN lights when it stops working. The IP address does not ping or arp. The SSID stops appearing. I have found no way to connect to it when this happens until I reset the configuration.
