Hello everyone, hope you are doing good.

I have some question regarding the archer c5 router, I have been using this router for more than a year.

I got this from my ISP, its is doing good . Now i have changed my isp so i got another tplink router(Archer c20) from my isp.

so i though i going to use my c5 router as extender, it has operation mode to switch between modes.

so I resets my router and configure like giving ssid to the router , after that i changed it to Access point mode.

For the past  2 months , it is working fine, now it is making some issues

My main issue is wifi keeps disconnecting , so one day i checked what is the problem by observing my router(extender). after rebooted my router(extender), everthing went fine, then WPS light blinks 2-3times and my 2.4 and 5 band wifi light black outs .

after 20 sec , the wifi lights came back ,and agin after 10sec the WPS blinks 2-3 times ,the wifi lights gone

Can anyone tell what is the issue,

by the way , i resetted and reconfigured it like 5 times, it gives the same results

My wifi lights itself shuting down, sometime i have to manually enable it on the router.

please tell any solution about this problem

Thankyou
