I guess im screwed. I used TP-Link products for 10+ years, this is the first time that firmware upgrade semi bricked my router.

@Joseph-TP Sorry for the late response.Here is my status window. The wireless speed is still abysmal since the firmware upgrade. Only the 36-128 channels are available for me.I literally tried...

@Joseph-TP Wired connections were normal when i plugged in my pc. I did a factory reset and it didn't helped :( Its from the 5 GHz band the 2.4 Ghz one got the right speed.

@woozle Yes i upgraded from an older version from 2023, both the QoS and traffic monitor is off for me.

@woozle It is on 160 MHz unless i have to reapply it again.

@Modan I forgot to mention the latency is also worse and jittery than before
