"Also do let me know how to revert back to the original firmware of the device or degrade to last firmware version?"

@Kevin_Z 

Thank you for your reply.

Ok let me explain in more details:

I having Archer C60 Ver 3.0

the old firmware:  1.2.0 Build 190115

the new Firmware:    1.2.0 Build 20201231

I upgraded through the "Online Upgrade" by clicking on "check for  upgrade", and NOT Manual Upgrade. which means upgrade  *.bin file has to be correct and genuine. 

These are issues that i am facing after upgrade:

- My SSID WiFi connection disconnected so many times per a day. both 2.5G and 5G

- I used to utilize Dynamic DNS through TP-LINK ID.  I cannot login to  TP-LINK ID any more. (tried on Chrome, Firefox, and Edge) plz refer to screenshot attached.

My issue has resolved after the replacement of the router- my router was in warrantly period(though i am still monitoring the new router - of the same model ,as i have just installed it). When i first contacted the Tplink  Customer care(India), they made me change the below settings on my old router(per them its their standard troubleshooting process for my type of case), though it didnt worked for me but still i am sharing the Changes that they made me perform(hope it work for you).

Reboot the router. -->>> Check Now.

But as these changes still didnt resolved my issue so they raised replacement complain and today i visited the service center and they replaced the old router with new one.

They upgraded the new router there itself to the new version on which i was facing the issue earlier

Firmware Ver: 1.2.0 Build 20201231 rel.39772(5553)
Hardware Ver: Archer C60(US) v3.0

Now i have configured the new router with my old backup settings and subjecting the router to the same conditions(multiple downoads/torrent on phone/laptop) during which i was facing the issues earlier [ i.e -initially intermittent disconnection of LAN/Wifi and than full terminination of connections when subjected to heavy download like torrents set on download(this issue didnt occured if one was only using  the internet for just browsing)  and the termination of connection either on LAN/Wifi was restored only  by rebooting the router and the issue would repeat again when subjected to same condition again and again,] earlier on old router and till now i have not experienced any issues.

Also while i was at service center the agent told me that in this router Archer C60 ver 3 we/they cannot downgrade the firmware as its not possible.

i will update the post , if i experience any issues on my new router or if the old issues gets replicated on new router.

i hope my this account would be of help to you.

Thanks
