OpenWrt One- 160mhz?

mortac8 · March 21, 2025, 7:37pm

Is it possible to run 160mhz on my OpenWrt One device? Whenever I set it to 160mhz, the access point doesn't show up to any of my client devices. If I bump it down to 80mhz then it shows up for my clients. I'm on channel 36. My configuration in general is basic and I'm on 24.10.0.

Any ideas? Thanks!

Is 36 a 160MHz chan ?

I believe you should try channel 50

I can't get 160mhz to work. Can I do 80+80?

Are you waiting for the DFS channel scan to complete?

brada4 · March 21, 2025, 8:34pm

Set country code, enable background survey, auto channel, and wait 1-10min for AP to come up. Thanks to bg survey dfs will be tracked in background.

Thanks for the help everyone. I wasn't aware of the need to wait a minute or more for the DFS scan. 160mhz is working for me now on auto channel.

Appreciate you all. Any way to get the transmit power with that config above 24?

Yes.*

*- If it's legal in your nation and the hardware is capable.

How to enable background survey?

Not all countries allow a 160 MHz channel between the U-NII-1 (5150-5250) and U-NII-2A (5250-5350) bands.

An example from Argentina shows that the two bands are separated:

root@mr70x:~# iw reg get
global
country AR: DFS-FCC
        (2402 - 2482 @ 40), (N/A, 20), (N/A)
        (5170 - 5250 @ 80), (N/A, 17), (N/A), AUTO-BW
        (5250 - 5330 @ 80), (N/A, 24), (0 ms), DFS, AUTO-BW
        (5490 - 5730 @ 160), (N/A, 24), (0 ms), DFS
        (5735 - 5835 @ 80), (N/A, 30), (N/A)
        (5925 - 7125 @ 320), (N/A, 12), (N/A), NO-OUTDOOR

Another example from Russia where the two bands are together and allows 160 MHz:

country RU:
	(2400 - 2483.5 @ 40), (100mW)
	(5150 - 5350 @ 160), (100 mW), NO-OUTDOOR
	(5650 - 5850 @ 160), (100 mW), NO-OUTDOOR
	(5925 - 6425 @ 160), (100 mW), NO-OUTDOOR
	# 60 GHz band channels 1-4, ref: Changes to NLA 124_Order №129_22042015.pdf
	(57000 - 66000 @ 2160), (40), NO-OUTDOOR

I don't know the case of 80+80 MHz.

EDIT: I just tested channel 36 at 160 MHz on the w1700k while in Argentina, and it works. I can see the channel at that width in the channel analysis on another OpenWrt router. So I don't know what's going on...

In radio section

option background_radar 1

channel will switch instantly on radar event

Can't we do this from a GUI?

lleachii · March 22, 2025, 10:46am

Are these questions related to the OP?

KOA · March 22, 2025, 2:13pm

OP was requesting for 160Mhz band and these are related to steps to enable that?
Aren't these?

lleachii · March 22, 2025, 3:22pm

I asked if your inquiries were related to the OP's inquiry
You inquired if the tasks in your inquiry are related to the OP's inquiry?

Nevermind - I must have misunderstood the purpose of your posts (or the parameters are attempts to override some radio regulatory restrictions in your country setting). My bad.

I will not try to break the law of my country just to get a bit more juice out of my router.
Nor I will encourage anyone to do so.

Cheers.

Not right now.
peas1234 created a luci-app-advanced package with extra wifi settings [MT6000 custom build with LuCi and some optimization - kernel 6.6.x) but this is for GL.iNet Flint 2 (GL-MT6000) out-of-tree only

Probably wishlist to expose also acs parameters
