@Dibesh Getting error code 4503 while updating firmware.

@Kevin_Z It is INWISP and I was using another tp-link router with the same ISP and it had no issues like this....will update the firmware from the above link once and update after some time.

I am having issues with Archer C20. Whenever I leave my router unused it gets disconnected from WAN automatically and everytime I have to go and save internet settings for the connection to work...
