I have a problem with my router where it stops responding for a few seconds to a few minutes.

When this happens my internet doesn't work and I am unable to access the router's configuration page at 192.168.0.1 or tplinkwifi.net.

Even if I am able to login, the config page doesn't load properly.

Please watch this video demonstrating the problem:

Problem started after updating the firmware to the latest version.

Resetting the router to factory settings didn't solve this issue.

My router details are as follows:
 
Model: Archer C6(IN) Ver 4.8
Firmware Version: 1.13.5 Build 240222 Rel.50991n(5553)
 
Your India website doesn't show links for my router model's firmware, it shows firmware for US version.

I had emailed TP-Link customer support for help in this matter on 18-April but no one has responded so far.

Please provide me links to firmware for current version and previous version so I can try reinstalling the firmware manually to see if the issue is due to botched update/install.

If nothing works I will take it to a service center.
Thank you.
