The Archer AX73 is still random rebooting despite updating to the latest firmware
Model: Archer AX73
Hardware Version: V1
Firmware Version: 1.3.6 Build 20240325 rel.39241(5553)
I bought this router three years ago, and have been experiencing frequent random reboots ever since. This leads to all connected devices losing Wi-Fi connectivity throughout the day. I don't have any range extenders connected to the router. When checking the System Log, I can see that the router shuts itself down and then restarts. I have seen on this forum that there are many people facing the same issue. I recently purchased a new power adapter to make sure the power supply was stable, but that did not fix the issue. I've also made sure that the router has the latest firmware updates installed as per the solution provided on https://community.tp-link.com/en/home/forum/topic/633288 but the update did not fix the problem either. Despite also trying to downgrade to the previous version 1.3.5 again, the issue persists. My network setup includes standard configurations with dynamic IP addressing and both 2.4 GHz and 5 GHz Wi-Fi frequencies. There are around 10-15 devices connected to the network, and Onemesh is disabled.
This recurring problem has become very frustrating and inconvenient, and I hope for a solution to be found soon.

Hi @Kaisa77
There are a few different cases related with unstable connection, including WAN connection unstable and wireless client devices unstable.
For WAN connection unstable (Router Internet LED turns red/orange occasionally):
1) Connect a PC directly into your modem to verify if your ISP Internet is stable.
2) Make sure the Ethernet cable between your modem and the Router is connected properly, replaced old cables with new ones.
3) Change the DNS Server of the Router, login to the web management interface of the Router, go to Advanced > Network > Internet > Advanced Settings, change the two DNS Servers into 1.1.1.1 and 8.8.8.8.
4) Go to Advanced > System > Firmware Update to upgrade the firmware of the Router.
For wireless client devices unstable:
1) Make sure the Router is properly placed, it should be put in an open area instead of inside a cabinet or shelf.
2) Login the web management interface of the Router, go to Advanced > Wireless > Wireless Settings, change the wireless channel into another one.
3) For 2.4GHz wireless client devices, adjust 2.4GHz channel width into 20MHz, for 5G wireless client devices, adjust 5GHz channel width into 80MHz or 40MHz to avoid interference.
If the issue persists, it is recommended that you can contact your local support for warranty consultation:

Hi @Joseph-TP
As mentioned in my post, it is not a case of unstable connections or clients simply being disconnected, the router REBOOTS itself randomly many times per day and takes several minutes to start back up each time. I tried with connecting my old router with the same settings and it works normally.

Hi @Kaisa77
If the other router works fine, it should be a hardware problem.

@Sourabhk I am sorry to hear that. It is unfortunate that the individuals at TP-Link do not seem concerned with addressing the issue. A router in this price range should include improved customer support. This speaks volumes about the company.

@Sourabhk I contacted support regarding this issue, as recommended here on the forum, but they informed me that since my warranty has expired, they cannot help me.

@Joseph-TP the solutions you have provided are for "WAN connection unstable" and for "wireless client devices unstable", however, this post describes an issue causing many Archer AX73 V1 routers to randomly REBOOT despite updating to the latest firmware. This means that even after restoring to factory setting, trying your solutions, using a new power adapter, no range extenders connected, the routers still randomly REBOOT many times per day. While the routers reboot there is of course no internet connection for around 5 minutes each time. This happens 10-20 times every day for me!
Can TP-Link please come up with a solution to this widespread issue soon?
