Networkmanager can't see home network

Hi,
I signed up to Vodafone (mistake!) in Feb 2022 and both my machines (Arch PC, home-build, or Arch laptop, Dell Latitude E6410) connected fine to my home router. Since the end of February/beginning of March, however, NetworkManager on both machines is not able to even see my router, but can see other networks in the area and will present the passphrase input window if I try to connect to one of them. There have been no hardware changes to either machine for a few years.

I have a hybrid work pattern, using a W10 laptop from my employer which sees and successfully connects to my router. Ditto my android phone. There's clearly some sort of mismatch between Networkmanager and the router, a Vodafone THG3000.

I've spent many hours over the last 5/6 weeks searching for solutions online: I've tried changing to dhcpd instead of wpa_supplicant's native dhcp (I think I got that right...), downgraded Networkmanager to the version before the problem started and tried turning off MAC address randomisation as well as playing the router's settings (they're now back to how they were). Obviously, none of them worked, so I'm calling it a day and posting here. Can anyone help, please?

Here are some outputs from various commands I found were common during my searches. They're from the laptop.

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

Re: Networkmanager can't see home network

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43224 802.11a/b/g/n (rev 01)

Does the other system have a broadcom chip as well?

iw scan:

Don't do that while NM is running.
As a matter of fact: stop NM (make sure wpa_supplicant stopped as well) and scan/associate manually (w/ either wpa_supplicant or iwd, you can use wifi-menu from netctl instead of the former)

Also, just to be sure: you did try to reboot the router?

Note, my router (vodafone89D476) isn't listed.

Last night's post was written using a wired connection from my laptop to the router. This post is being written on my PC using my phone as a hotspot (CUBOT J3 PRO). So, both the laptop and PC have no difficulty connecting to my phone.

Previously, I'd been searching for networkmanager problems but your suggestion regarding iwd has just lead me to this post: 

https://www.reddit.com/r/archlinux/comments/v2payc/iwd_cant_see_my_home_wifi_network/

Wireless-regdb isn't installed on my PC, but since both machines can connect to my phone that wouldn't seem to be the problem. I haven't seen any way of changing the channel on the router, nor anything about the regdom there.

Re: Networkmanager can't see home network

Did you try the LTS kernel (linux moved to 6.2 on Feb 20th)

We've different chips, both bands, doesn't seem to be the router and NM and it's scanning tactics are out of the equation - so it has to be in the kernel space and the common parts of that stack.

Re: Networkmanager can't see home network

I'm not familiar the the LTS kernel but will give it a go in a few days when I have a some time.

I do have some good news: my PC (atheros device) is connected to my router on a 2.4GHz channel as I speak and I did a full system update a couple of hours ago. Prompted by the link I gave above and using the network configuration/wireless wiki I installed wireless-rgdb and set the country to GB. Viola! Connectivity restored and functioning as normal.

The laptop (broadcom device), though, is a different story. Even with wireless-rgdb installed and the country set to GB it still refuses to see my router. Perhaps, the problem lies with the broadcom chip after all.

Re: Networkmanager can't see home network

I installed linux-lts 6.1.24-1 on the laptop last night and no wireless interfaces are showing, just the ethernet. After some digging:

lspci -k (LTS kernel) shows

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43224 802.11a/b/g/n (rev 01)
	Subsystem: Dell Wireless 1520 Half-size Mini PCIe Card
	Kernel modules: bcma

whereas with the normal kernel it shows

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43224 802.11a/b/g/n (rev 01)
	Subsystem: Dell Wireless 1520 Half-size Mini PCIe Card
	Kernel driver in use: wl
	Kernel modules: bcma, wl

The broadcom-wl package is installed on the laptop and the module bcma is blacklisted. So, the LTS isn't finding the wl module. While trying to find out how insert the module into the LTS kernel (sorry if that's gibberish - inexperience!) I found this:

https://wiki.archlinux.org/title/Broadcom_wireless

which recommends using the brcm80211 drivers.

I'm wondering now if I should uninstall broadcom-wl and use brcm80211 since that's included in the kernel. Could that be a solution and will just uninstalling broadcom-wl be enough?

Re: Networkmanager can't see home network

https://archlinux.org/packages/communit … m-wl-dkms/

You can try the brcm80211 driver (brcmsmac, to be specific), but you suggested that

06:00.0 Network controller: Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) (rev 01)

faces the same problem and then it's likely not a bug in the specific driver.

Re: Networkmanager can't see home network

Thanks again, Seth.
Finally, I've had time to investigate this more.

Firstly,

faces the same problem

isn't quite right.

The situation now is:
1. PC/Ath9k.
Installing wireless-regdb and setting /etc/conf.d/wireless-regdom to "GB" seems to have solved the problem. Again, I'm using the PC connected to my router to write this post.
Perhaps I missed a change to wireless configuration requirements around the end of February.

2. Laptop/BCM43224.
NetworkManager still can't see my router and the problem could be linked to the current driver. So, it's probably worth tryng the brcmsmac driver - once I've found out to install it.

It just dawned on me earlier that both machines are dual boot, with Windows 10 on the laptop, (It's been so long since I booted into Windows on either I'd forgotten about them... I think a loud 'Doh!' might be appropriate...). Anyway, just to rule out hardware, I booted Windows on the laptop and it has no problem connecting.

Re: Networkmanager can't see home network

What's your kernel? There was an actual regression in the kernels wext interface - which is used by wl - in 6.2.5/6.1.somethingsomething which should be fixed on an up to date kernel
