Difficulties maintaining 160 MHz channel bandwidth

[ColinTaylor]

If you don't have 3 to 10 minute scanning dropouts then sometimes the DFS space can be a blessing.

I've never seen any delays. On the rare occasions when radar detection has forced a channel change it happens immediately.

Stop adding extra "u"s to everything I hear that enough at work all day

Only if you guys start pronouncing "solder" properly.

I've given up with 160mhz for the time being. Just seems too fussy.

My S23, can't seem to hold onto the 160mhz at all.

Tried the following:

20/40/80/160
160 only
Channel 36

Just seems hit and miss.

It's by design that the router automatically drops to 80mhz when no supported device is connected, although this conflicts with practical needs.


Naturally, some people will need 160mhz. The fundamental problem is that this is the maximum wireless rate available in some areas (no WIFi 6E/7), or can you try to connect your phone to a network cable? It is arrogance to assert that others don't need 160mhz just because you don't need it.

I've enabled 160 only and also tried it with 20/40/80/160. Just seems that my S23 wants to stick at 80mhz for some reason and won't switch over to 160mhz.

It feels temperamental. Unless I'm not doing something right?

OK, I do not need 160 MHz. My FIOS is "only" 100/100.

But, my router and node both have been at 160 MHz for the past week. That is when I last tested Merlin beta firmware then went back to Asus. No fancy WIFI config. Basically default settings except for enabling DFS channels. My 160 MHz enabled AX and AC clients are happy and my new Samsung A54 is very happy at 80 MHz with WIFI calling working just fine!

It is temperamental, just like 40mhz on 2.4 (actually worse since 160 on 5ghz must use DFS frequencies). You need low interference and no radar in your area.

When the router drops to 80mhz, you need to wait 5 minutes to switch back to 160mhz when connecting to a device that supports 160mhz. The speed of route degradation is much more aggressive and rapid than that of upgrade.

I believe sticking 160MHz wide channel in Asuswrt 386_46061 (and Asuswrt-Merlin 386.5_2) firmware for RT-AX86U (and other models) was actually a bug fixed in later firmware releases in order to better follow DFS channels use requirements. This change affects not only Asus routers, but anything else on the market using the same hardware and Broadcom drivers for it. This is not coming from Asus at all and totally unrelated to Asuswrt-Merlin.

Although a long time has passed, I still want to say: ASUS's newly released GT-AX6000, BE96U, and BE88U can all maintain 160MHz stably.

Does this switch actually do anything?

No matter how I set the channel bandwidth it always chooses the frequency the client wants to connect at. I thought setting this to 160MHz would only allow devices that support 160MHz to connect. But that is not the case, I still have devices connecting at 80MHz and 20MHz.

I just asked a question about this lol your issue is still happening and we are in 2024

You've got multiple explanations how DFS works. No matter how many times you ask - the answer will be still the same.

The driver from Broadcom simply doesn't just run on 160MHz only. It will always keep 20 and 80MHz channels open as well. It's unfortunate, it would be helpful to diagnose some issues.

near seamless dropping from 160 back to 80 only occurs if the control channels are non-dfs, some of these units auto-set a 160mhz capable channel bond using a dfs channel as the initial control channel, which you will find drops 5ghz entirely for several minutes.

if you want 160mhz to actually be useful when capable devices are about, invest in 6ghz devices, or force 36 as the control channel, however be aware that on AC class devices, sub 100 control channels are still weaker on the TX strength.

some packets will still be lost as the fallback occurs, and again as it promotes again (tested to be between 4 and 8 with pinging the ap via cmd prompt)

I found that strange as it's something I've never experienced, so I tested it. On channel 124 (manually set), my router switches unnoticably between 80 and 160MHz when I connect and disconnect my ax notebook. When you say "near seamless" do you mean I should notice something, or is it just a few lost packets that make no difference to the actual user experience?

Not what i'm talking about.

If your DFS range is not usable - you can't.
