TP-Link Archer AX6000 - 5GHz band does not keep the selected channel

2021-09-20 20:46:38

Model: Archer AX6000

Hardware Version: V2

Firmware Version: 1.0.3 Build 20210719 rel.18941(4555)

Hi, I bought this router less than a week ago, but sadly I encountered an annoying issue: even selecting manually a certain channel on 5GHz band (channel 44 in my case), randomly my connected device (Intel WiFi 6 card AX200) switches to channel 36 (which halves the performance to 1.2gbps instead of a maximum of 2.4gbps), it never happened with my old router from the ISP; the AX200 card has the latest driver (22.70.0.6) and the latest firmware is installed on the Archer AX6000.

Could this be a bug of the latest firmware?

Thanks in advance.

@TheGreyFox

When you manually switch to channel 44 on the router web GUI, does it display 44 on the Status page? If yes, may I know where did you see it switches back to 36 on the Intel WiFi 6 card AX200 device? Can I have a screenshot of it?

How about other devices that connect to the 5G network of the router, does it also display a channel 36 whereas the channel displays as 44 on the router's Status page?

Try to test this by switching to other channels such as 48 or 40, will it switch back to 36?

Yes the channel 44 was correcly selected and saved on the GUI, I saw the channel 36 on the wireless properties of the AX200 card.

I made some other attempts, this problem comes up only if I modify something on the wireless options without reboot the router, and sometimes the 5G band completely disappears when modifying something without rebooting (and not shows up even after 15 min).

After rebooting, everything is working fine without any challel switch and the 5G band works fine.
