[SOLVED] Network Manager Can't Authenticate When Resuming from Suspend

KrunchTime · 2017-03-22 22:19:40

This problem has been going on for quite awhile. I spent a few minutes awhile ago searching for a possible solution, but couldn't locate anything that seemed worthwhile.

When waking up from suspend, Network Manager attempts to re-authenticate with my router. I click the Connect (?) button, but the existing password is not accepted. I then have to reboot to use WiFi again under my BL-Unstable instance. For a while, I was able to get around this by reconnecting via the Connect to Hidden Wi-Fi Network option in Network Manager, but that no longer works for some reason.

Have you tried restarting NetworkManager.service?

Does this bring your connection back up:

# systemctl restart network-manager.service

EDIT: Ninja'd...

@damo: No, I have not tried restarting the service. That may work, but then that begs the question, why should I have to?

@Stick: I'm currently in my Hydrogen instance. I'll boot back into my Unstable instance and give your suggestion a try.

Edit: OK, I've suspended twice and Network Manager has reconnected both times without issue. It will happen again, so I'll try restarting Network Manager when it does and report back.

When this happens, what does your ifconfig -a look like? Is your network stack operational at all? can you ping your own interfaces?

When you lose connection, maybe check to see what the output of

nmcli general status

^Never tried ifconfig -a. Never tried, nor do I know how, to ping my own interfaces. However, thanks for chiming in.

Umm okay.. well try the command:

ip address

having to restart the net manager service shouldn't be needed obviously. perhaps a dhcp lease issue?

I'm not so sure about that. I've read about suspend issues, such as Wi-Fi, under Linux and Network Manager is disconnected when I suspend my desktop or my laptop. When I resume, Network Manager attempts to reconnect, but sometimes unsuccessfully. When unsuccessful, I get a prompt to enter the authentication password.

Well, the issue happened again a few minutes ago. Restarting Network Manager worked using the command HoaS provided. Following is the info Horizon_Brave asked me to check (prior to restarting Network Manager):

Results of nmcli general status:

Thank you to damo, HoaS, and Horizon_Brave.

Can we see the output of this:

systemd-inhibit

We could try a script in /usr/lib/systemd/system-sleep/ to run that `restart` command but systemd-suspend.service(8) says that this is a hack and that the Inhibitor interface should be used instead.

TBH, this is all over my head a little bit so I may have to investigate some more...

Horizon_Brave · 2017-03-24 19:38:33

Btw what wireless card/manufacturer do you have here? and what kernel?

Are you using the proprietary driver with that?

If so, try the open version instead, it will probably work better in respect of suspend behaviour.

This command will show the driver in use:

lspci -k | grep -A2 BCM4352

KrunchTime · 2017-04-01 22:12:36

^ I don't know if I'm using the proprietary driver or the open driver. I do know that I had to install the package broadcom-sta-dkms to get wireless to work. Output of the command you suggested:

03:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)
	Subsystem: AzureWave Device 2123
	Kernel driver in use: wl

That's the non-free driver and they tend to not integrate with the system as well as the open drivers.

You could try the non-proprietary version, that may fix your problem but outright performance may suffer.

The real problem here is the hardware choice — Broadcom's support for the F(L)OSS community is atrocious and their products should be avoided, IMO.

KrunchTime · 2017-04-06 00:03:25

I think I'll stick with the non-free driver. This is the first real issue I've had since I bought the computer.

Yeah, I've read about Broadcom issues, but again, this is the first real issue I've had.
