Enabling 160MHz BW on 5G-2 on GT-AX1100 only gets 80MHz enabled in Wireless Log.

[kennethdavid]

Both bands are operating at 160mhz for me now on this firmware.
for 5ghz-2 I had to set the channel manually to 100 for it to work.

Hi, I'm not sure how to enable the 160mhz band explicitly? I don't have any such option anywhere on the UI for 5ghz-2 on my ax92u. Here is an excerpt from the log, it shows the 160mhz capabilities, but the connection to the other stations is 80hz.

The only way I could actually get the 160 was to select only the 160 Mhz in the channel bandwidth (not 20/40/80/160) turn on the 160 check box and force the control channel to 124. I have never been able to get both 5Ghz bands to use 160Mhz at the same time. If I turn on the 5G1 band then the 5G2 band will not select 160 Mhz even if I try to force it.

Did you you anything special to get 160 to work on ax92u? I have 160 enabled but still only getting 80. I've tried to disable wmm as was suggested for the ax11000 but the disable option is not longer there on the ax92u with the latest firmware.

For my AX92U, I set the 5Ghz-2 band to AX Mode only, checked 160Mhz, selected 160Mhz only, and set the control channel to 100. Applied the settings, and about 45 seconds later it was working.

That did it. Thanks!

Ok, I'm not sure I'm clear what I need to do, I got the AX11000 now and added to my setup as the main AP. I can't manage the AX92U directly, if I try to login to the web interface it redirects me to the interface of the AX11000 as I have everything in AI MESH.

My AX11000 will only let me set 160 enabled on 5hz-1, but the AX92u I think only supports 160mhz on 5Ghz-2?

What am I missing here? Sorry guys, I know this thread is pretty clear, but I can't get this to work at 160. (By get this to work, I would like the backhaul connection between the ax11000 and the ax92u's to be using 160 channell bandwidth to each other.)

Also, I don't have an option for channell 124 oddly!

On the AX1100, try not using 160Mhz on 5Ghz-1. Apply the settings. Upon reboot, try the instructions I posted for 5Ghz-2, and apply. That should fix it.

ok no matter what I do, I don't get the 160mhz on 5Ghz-2 checkbox. I'm going to try to do a factory reset on the main router (AX11000) and see if it helps.

OK finally got this working:

It wasn't a firmware reset, which I did do to both the router (ax11000) and the 2 AX92U aimesh nodes.

I ended up having to set the flags manually in NVRAM of each router and each AIMESH node from SSH and then did a "services restart_wireless" to get this to work! Working flawlessly now.

Thanks for all the help guys.

[bosu1787]

how you flags manually in NVRAM?

i have the same problem .... on 5g-1 on ax11000 160mhz works great but on ax92u i cant get 160mhz. i dont need 160mhz on 5g-2 if i manage to get on 5g-1 160mhz on ax11000 and ax92u its fine.
