The Wireless 5GHz channel has dropped from 160Hz to 80Hz

[sfx2000]

It might as well stay on channel 36 and drop the bandwidth to 80MHz.

Thanks - that was my point exactly - wonder if this is an artifact with how the wireless driver is initalized when configured as 160MHz BW - since DFS has to come into play, if there is a WL event that causes the driver to tune away from the extended channels, that it thinks it in automatic mode, doing the scan for activity and tuning to what it thinks is a "better" channel...

I apologize, I know this is an old thread, but it is currently very relevant to me. I have the exact same router the GT-AX6000 ROG with the latest merlin 3004.388.8_2_rog, and I have noticed a very similar event to OP. Where I live there is an Airforce Base, so I wouldn't be surprised when the Blackhawks come flying through as low as they do, that it would indeed kick me from my channel 48 @ 160MHZ to channel 44 or 36, but like you indicated, it doesn't change back to 48 and the bandwidth changes to 80mhz unless I readjust the router. I've noticed however, that my nearby neighbor has a TP-Link BE19000 Tri-Band 7 Router, and they have dual 5ghz channels, one is always trying to steal my spot and it typically wanders around the lower channels. Most of the time we are both broadcasting channel 48 @ 160mhz at the same time without any issues, I have 2GBS Fiber, and I can actually almost use all of that bandwidth when I'm using AX at 160mhz, so I want the channel to stay put, but it will migrate to a different channel and extension channel, typically like 44 or 36 and a high end extension channel, until I realize that my 160mhz bandwidth has been compromised, and then I reset the channel on the Wireless Page, and the radios reset and everything is back to 48 @ 160mhz. I'm wondering is there a way I can force my neighbor off channel 48? Perhaps some industrial grade tinfoil, or microwave maker or something, cuz that TP-Link Router is really messing with my gear.

Is there a way to keep it forced onto 48 at 160mhz? Even though my neighbors channel overlaps directly on top of mine, it is by far the fastest channel at 160mhz, I've tried the others and the interference increases to the point its hovering in the -70 range, when the same device on the 48 channel with 160mhz typically gets -60db. Should I just buy a 1000$ router and see if I can overpower the neighborhood?

No.

Your neighbor has nothing to do with your router switching back to 80MHz. You may complain to the military base near by.

Well there is a was, just not a legal one (and your neighbours will hate you).
If you set the country code to #a; you effectively disable DFS, set the signal to chipset max and also unlock all of the channels....

lol, I'm sure my neighbors will get over it, they aren't too bright from my experience, which is also why I was surprised they have such a heavy duty router, although they are pretty well off financially. I don't like TP-Link Routers, but that specific model has some significant coverage. I will sometimes get nearly the exact same signal from their router in their home, from my router in my home (typically at the furthest point from my router), which is pretty far (I dunno exactly my home is about 1700 sq, ft.) Those helicopters are the worse though, not a lot of jet activity in my area, ton of helicopters... I can hear one off in the distance as I type (Sigh), its like 'Nam out here, except completely opposite environment. Also they love flying their ac130s around, those I don't mind.

Thanks for the input! I appreciate it, I was also going to also ask, since I have a two floor home, the signal obviously degraded due to the router being on the first floor. I have an RT-AX82U, and it has a double port (I think WAN and Lan 4 aggregation?) to make it able to accept 2.5 GB bandwidth, however I have no idea how that would work. I've tried looking online, but I guess I reckon I would need a 2.5GB Switch from my Modem to my main router and then two ethernet cables running to WAN and LAN4 of my RTAX82u and place it up somewhere high in order to continue to take advantage of the 2gbps speeds from my fiber provider. Does AI Mesh degrade the signal of 160mhz DFS? Just curious, I know repeating isn't good and can cut the bandwidth in half, but I know AI mesh is quite different. I've had trouble with the whole frequency falling out on AI mesh in the past, so I haven't been trying to utilize it. Hope this makes sense? lol

Thanks!

in order to continue to take advantage of the 2gbps speeds from my fiber provider.

You can't. AiMesh doesn't support LAN aggregation backhaul, the LAN ports on this router are up to Gigabit, exceeding Gigabit on Wi-Fi with no DFS and 160MHz client support is unlikely and since AiMesh uses the same channels the total channel bandwidth is shared between the main router and the nodes. Many folks pay for high speed ISP plans first (promotion!) and then realize they can't really use it (oops!). The ISPs are happy.

i am seeing the same issue on multiple routers gtaxe16000 and gtax1100 pro.. i have to hard code the control channels on both 5g bands to 36 and leave the 5ghz-2 band to itself.. upon reboot of the routers it immediately connects both at 160 so at that point it is obviously clear. . but then once it drops to 80 never goes back up.. we are in the boonies and there is no radar near me..

Doesn't mean anything...

Radars can go for very long distances depending on type, just a plane or helicopter flying over is enough also, heck even Mobile phone repeaters that use 5GHz as a backhaul between repeaters can cause interference.

So safe in the boonies? Not quite!

I apologize for reviving an old thread, but I just want to include in here that the newest firmware fixes the 160hz channel problem for me on my rt-ax86s. I was having the same issue as other people in this thread. Get booted off from 160hz to 80hz. Or even not getting booted off but just disconnecting just from a shutdown, and when it reconnects to just goes to 80hz rather than 160hz. But so far that has not been the case anymore on firmware 3004.388.9_2.

Now I stay on 160hz consistently. Whenever there are "only" 80hz devices connected, it stays at 80hz. But when a 160hz device comes back online, my router rechecks the 160hz channel and then establishes a 160hz connection again. Hopefully the people who gave up on the 160hz channel can try again and see if it's working for them.

Another new behavior I noticed is that when a reset happens. The behavior before was the 80hz on 5ghz is unavailable until the 160hz is clear and established, usually takes a lil over a minute. But now, 80hz is available for connection right away. Then once 160hz is clear, it also becomes available.

Maybe just the interférence changed (gone away). Indeed some FW changes. Or just on the right channel...

If you are on Auto channel selection, if the 80MHz (not hz) falls outside of DFS of course there is no wait time...

FW can not change this behaviour that is demanded by regulations.

I wasn't implying FW changed the behavior. I was trying to highlight that before this new firmware, maintaining 160hz connection was impossible for me, and now that it's fixed, I'm witnessing a behavior that never happened before because it was bugged.

My control channel is 100 btw. And it's on Auto. And no, I never had interference on the channel. Channel 100-128 is completely clear and always has been
