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

Level 8
ROG GT-AX11000

Enabling 160MHz BW on 5G-2 on GT-AX11000 only gets 80MHz enabled according to the Wireless Log. Firmware Version:

It doesnt matter if you disable the 5G-1 radio in the Professional tab, the 5G-2 never gets 160MHz up according to Wireless log under any circumstance.

5G-1 has no problem enabling 160MHz bandwidth!

Coincidence or not, I noticed the same behavior on the RT-AX92U. 5G-2 could not get 160MHz up according to Wireless log even though it clearly has that option set.

But, I don't believe in coincidences....

So clearly Asus has some work to do on their GT-AX11000 and RT-AX92U to fix true 160MHz setting on the 5G-2 band...

On the Advanced - QoS page there is a WMM (WiFi Multimedia) TAB/page with settings for each WiFi Band. Check those settings.

I've tested it and you are right. I've send this problem to Asus and hope thei will pick it up.

did already, no answer. But why anyway? This is a software/hardware problem. In most small countrys they don't even know what we talk about when we try report problems like this. They are only sales representative.

Why isn't your service go further then this? It's a router of 500 euro. C'on sir. Make Asus great again.

Still not fixed lol. I wonder if this router can even do 160MHz on both 55G-2 and 5G-1 at the same time

for GT-AX11000 still has the no 160MHz BW bug on the 5G-2 band in wireless log.

So the router in this state have NEVER actually been an 11000 speed router to begin with. The truth is the firmware has actually never allowed it LOL!

This is actually a cause for a refund in its current state of GT-AX11000 and RT-AX92U , the box states the impossible, a fantasty! The 5G-2 band can under no circumstance ever enable 160MHz BW on these two routers!

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.
