New router firmware causing ping spikes
Day before yesterday TP-Link pushed me to update my router firmware to the version mentioned. Since then, I'm facing constant ping spikes even when pinging my router from the desktop directly via a Cat-6 Ethernet cable. This is ruining my whole internet experience by causing voice drops during meetings and unacceptable lags during browsing.
Prompt help will be appreciated

Hello @swastiknag02 ,
Welcome to our community.
May I know if your network topology diagram is as follows:
ISP modem—router)))((( client devices
(Note: — stands for wired connection,)))((( stands for wireless connection )
Have you enabled the QoS? If yes, please disable it for a try.
Please also take screenshots with the ping result and send them here.

@Joseph-TP I replied to the ticket accordingly, also mentioning a non-functional LAN port due to the firmware upgrade, to which they asked me to communicate to the TP-Link local support with my issue, asking for a replacement. So, I emailed local support for a replacement
