AX6000 5GHz band issues

Model: Archer AX6000  
Hardware Version: V2
Firmware Version: Archer AX6000(US)_V2_211118

My newly bought AX6000 seems to be having some issues with the 5GHz band randomly dropping after a few hours of uptime. I've tried factory resetting, reinstalling the latest firmware, toggling features like OFDMA and MU-MIMO and changing the security settings. None of these improved anything.

At first I thought it was a thermal issue so now I have a fan below the router which makes it run a lot cooler, however this also did not improve anything. For my desktop, 2.4 seems to be working fine without any random drops. 

My phone constantly has problems connecting to both 2.4 and 5Ghz, as it randomly seems to lose internet connection while apparently still being connected to the wifi network.

Hello @Thomazz 

 

I would suggest you try to modify the 5G settings on the AX11000, you can run a Wi-Fi analyzer on the phone to review the 5G networks around you, then choose one that with less interference with others to observe if the connection will be more stable.

 

You may go through this FAQ as well - such behavior could be caused by wireless radar systems around you when using DFS channels. You may read this story too to see how to optimize the 'wireless channel' and 'channel width' selection in your router.

 

You may also refer to this article to check if it is located in a proper location:

  @Kevin_Z Thank you for your quick response

My router placement seems good since I currently have it on a shelf around a meter and a half off the ground in the center of my house.
There don't seem to be many 5GHz access points around me, so I have set the 5GHz channel to 36 and width 160MHz.
I will monitor the connection and see if it's more stable. If not I will try using 80MHz for the channel width so no DFS channels are used.

Also sorry for the duplicate post, I couldn't find it back so I assumed it was somehow removed

No worries, I just found there are duplicate threads and I want to remind you of that.

  @Kevin_Z Changing to a set channel instead of using auto-select seems to improve the connection stability significantly.

I still had some small stability issues using 160MHz at channel 36, so I ended up further excluding DFS channels from the spectrum by using 80MHz width instead.
So far I have yet to experience any stability issues / drops and it looks like my problem has been completely resolved.

A single apple device still has occasional issues connecting to the 5GHz network, however I have my suspicions that this is caused by a problem with the device itself.
If I end up finding a solution or cause of the problem I'll let you know.


Thank you for your help and support!
