Card with chipset BCM4360 [14e4:43a0] (rev 03) doesn't see 5Ghz networks with high channel number.

[Matteo]

The card Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) doesn't see 5Ghz networks with an high channel number, if you change the channel back to a lower one the network will be found again.

In my case with channel 104 the network wasn't seen by the card, with channel 40 it works fine

[carlinyos18 (carlinyos18)]

Any updates? Im running ubuntu 16.10 with an archer t8e and still no 5ghz. In my case theres no country code, so only 64 and 66 channels are shown were i use "iwlist wlp3s0 freq". My wifi is in channel 100.

[Matthäus Brandl (matthaeus)]

Is it possible that the driver doesn't support the DFS channels? (they must be yielded to prioritized users such as weather radar)
https://www.wi-fi.org/knowledge-center/faq/what-is-dynamic-frequency-selection-dfs

[Laryllan (laryllan)]

Same problem here, maybe it doesn't respect the crda settings provided by Ubuntu?
https://packages.ubuntu.com/artful/crda

[zebul666 (zebul666)]

Same here, channels 12 and 13 are not seen while crda is set to use FR region

[Damir (damir-sultanbekov)]

Same problem. My card is TP-Link Archer T6E

[negora (negora)]

I've an ASUS PCE-AC68 card and, years ago, I gave up configuring it with DFS channels. Apparently, it wasn't able to see them. I even thought that they were forbidden in my country...

Months ago, while I was doing some bandwidth tests, I decided to try again. I switched the channel to a DFS one in my router (an ASUS RT-AC68U) and, initially, the card couldn't see the new channel either. But I waited 5-6 minutes and, for my surprise, the card was able to detect it! I decided to wait so much time because I had read, somewhere, that DFS channels might take even minutes to be detected. And indeed, that was the case with this ASUS card. The Intel card of my laptop, though, detects it immediately.

My tests were made with Debian 9 and the driver "broadcom-sta-dkms" 6.30.223.271-5 .

[Laryllan (laryllan)]

Which channel did you use exactly?
After reboot, how long does it take to find the channel again?

[negora (negora)]

Hi again. I'm sorry to say that I remembered wrong :( . I would swear to have seen the DFS channels when running the command "nmcli device wifi list" with the PCE-AC68, but I'm being unable to reproduce that situation again. Neither with Debian 9 nor Windows 10. So I guess that I mixed up the results of one card with this one. My apologies.

[Enrique Moreno Tent (enriquemorenotent-gmail)]

Happening to me too.

[Nikolay Kichukov (hijacker-c)]

same here, GNU/Gentoo Linux with broadcom-sta driver package. 5 Ghz band works only if a lower channel is configured on the AP.

[M. Gonzalez (whatausername64)]

I have an Asus PCE-AC56, with a BCM4352 chip and currently using bcmwl-kernel-source drivers, and it's also affecting me.

[M. Gonzalez (whatausername64)]

Also that on 5GHz, channels 40 and 48 do work, but any higher than that and the wifi card isn't able to see the WiFi anymore

tested it myself, and including channel 52 and 56 aren't able to show

[Klionheart (klionh87)]

This is still very much a valid issue as of bcmwl-kernel-source 6.30.223.271.

Is there any news/known workaround?

[Marc Paris (marcparis)]

I have encountered this issue on Ubuntu 18.04 and now again on 19.10. ASUS PCie AC88

[vishal733 (vishal733)]

An issue even in March 2020. I tried Ubuntu 18.04, and Ubuntu 19.10.
I'm on a Macbook Pro.
If I switch to channel 40, 44, 48 works.
But if I move to channel 149, 153, 157, etc. it stops getting detected.

And as you may understand, the speed that I get on channel 40/44/48 is quite slower compared to what I can get on 149.

It will be great if this bug can be prioritized....

2024 and this bug is still around. The card is unable to pick up a wifi that has a channel higher than 48. What could be done in order to have this bug fixed ? Anything I can help with, like providing tests idk

This bug is not in Ubuntu, but in the Broadcom driver, which AFAIK has not had a new release since 2015. This is a closed-source driver so they are the only ones who could fix it.

I know that it is a closed source driver and to be honest with you, this is the only place where I see this bug being reported. But I really don't know where else to report it other than the ones that are currently working on this driver (which again, idk of to contact them)
