Physical location - 30 ft and 1 wall separation

I am facing below issues
1) Random restarts. Stuck at power on.
Intermittently, my WA850RE would restart. Acutally I am not sure if it does that or not.
* But what does happen is that the RE is stuck with only Power light on.
* It does not boot up completely.
* No wifi connection to main router A
* Nor does the RE wifi B start
* issue can be reproduced, if I turn off and on the wall socket under 3 sec interval
* I have observed that if I wait for 10 - 15 sec between power off and on cycle, it would boot completely.


2) Throughput diminish issue
Off and on connectivity to RE would stop. Throughput will keep on decreasing till zero. So I set up a ping and I observed that ping time will increase upto 4000 ms and then RE will become unreachable. Physically all lights would be on. At this time, I have observed that even the main router would not be accessible.

Any ideas what could be the issue.
