Archer AX55 - unstable connections after upgrade
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Router had been working with no issues for months. On Friday, 17-Novembet morning it automatically upgrades the firmware to version 1.2.5 Build 20231025 rel.50143. Since then, it has tons of issues. It doesn't connect. The connections keep dropping. It connects to one device and then fails to connect to other.
I've done rebooting, restarting, IP clearing, restarting multiple times. This upgrade messed this whole thing up. Called TPLink support multiples times but no use.

I did a factory reset also and the problem returned. Downgraded to previous firmware and no problems at all.

@AnnetteT correct. Factory reset doesn't take it to version it came with.
You have to downgrade the version to fix this issue. I did it just after posting the issue here and it worked fine. Process is quite simple.
1. Download the last firmware version from this site of TP-link - make sure to choose the correct version of router (mine is 1.6) while downloading the firmware
2. Unzip the content
3. Connect to your router via Ethernet (hardwire) and login by URL 192.168.0.1
4. Go to Advacned -> System -> Firemware Upgrade and under Local Update, browse the bin file and click Update. It takes couple minutes.
I realized that automatic update was ON, which I have turned off now.
This is really bad of TPLINK that they released a buggy firmware without testing it properly.

I appreciate all of you replying to my post.
It seems that one of the major issues with this new firmware release is that there is a problem with
how the AX55's DCHP server manages assigning IP addresses to network devices.
As an experiment before downgrading the firmware, I changed the default DHCP Address Lease Time
from 120 minutes to 2880 minutes (48 hours maximum allowed), and the problem with disconnects, and
failure to connect/reconnect new wireless devices, went away.
Everything has been completely stable so far for the past 14 hours. Will the problem return in 48 hours?
I don't know. But right now I can connect, disconnect, and reconnect wireless devices without any
problems. So, it is interesting.
I will keep you posted. Thanks again
