I have a CPE210 connected to a Cisco AP (00-18-0A-XX-XX-XX) in AP-Client-Router mode with ~43 dB SNR. Assume saved configuration.

 

This works fine some time (1-2 days), but then the Root-AP-SSID disappears completely. Which means, WAN is disconnected and the Root-AP-SSID doesn't appear in a Survey. You could hit Refresh as long as you want, it doesn't show up again (but many others).

 

Reboot fixes this immediately. Configuration remains unchanged (as saved before), but WAN is connected. Survey also works as expected again.

 

Workaround via Ping-Watch-Dog "fixes" this - but interrupts service for a few minutes each time. Lock-to-AP doesn't seems to make any difference.

 

Quite nasty, isn't it? Smells like a bug...

What are the signal strength and noise of the CPE?  In general, we believe that the signal strength is higher than -75dbm for the device to work properly.

@Scott.Tao Currently I have (when connected) Signal Strength -55 dBm, Noise Strength -100 dBm and SNR even better than before: 45 dB.

Should be more than enough for a stable connection. But Site Survey still doesn't show the Uplink-AP sometimes until Reboot.
