Network Connections after wake from sleep

Issues & Assistance Networking Support

I have woken up my MBP several times after it goes to sleep, and each time I am finding the Network Manager service works fine, Bluetooth is on and connected to my BT keyboard and mouse, but the wifi is dead due to no active connections. I would like to fix that, but I am struggling with the Arch way of doing it. I read one should create a restart service. Not sure that is exactly the solution. My computer stats read as follows from garuda-inxi below. Any hot tips here on what to do so that my Wifi can connect to an Active Connection once I re-awaken the machine?

By Sleep I also mean something overnight happens. If I just use Logout and choose Sleep and then re-awaken the machine, the network connection is fine. It only when I leave the machine for many hours, that this coma happens.

I can save the system status when this happens I suppose and then diff that with this garuda-inxi output to find the culprit?

I think you could try something like this.

For sure you will have to change rtw88_8822ce with brcmfmac. Probably nothing else, but read it through…

Unfortunately this does not work. Service is down and out and not revivable. Even running the network-restart.service from the command line does not revive the list of available network connections.

Something else must be responsible for killing the listing and not reviving it. So far, only a brute-force “restart” brings back network connections.

That’s an interesting clue. :thinking:

Try disabling MAC address randomization and see if you notice any difference.

Try also some other kernels.

These claims are totally unsubstantiated!!!

Where is the textual evidence of the contents of the service you wrote?

I always include the correct command to list the location and the contents of the service in every service I write:

How could we possibly know if your service was written correctly, if you do not post the command output for us to review the service you created?

Where is the terminal output of the status command I always include in any service I write?

How can we possibly know what the problem with the service is, when you do not post the errors from the execution of the status command?

Where is the terminal output of the commands you ran?

We are not clairvoyants! Without textual proof, for all intents and purposes, nothing was run, and no errors were ever thrown. For all we know you simply executed a null command. Where’s the substantiation for your claims?

You don’t have much hope of ever finding a solution with responses such as:

You need to provide detailed and accurate feedback if you wish to solve your problem. Answers such as you’ve provided only serve to frustrate forum assistants and are usually very counterproductive. Sorry if this comes off as a rant, but it is a little insulting when someone basically claims a service I wrote is totally useless without providing any evidence to back up these kind of statements.

You can run the following commands prior to suspending to unload all of your networking components:

nmcli networking off
sleep 1
sudo systemctl stop NetworkManager
sleep 1
sudo ip link set wlp3s0 down
sleep 1
sudo modprobe -rv b43
sudo modprobe -rv b43legacy
sudo modprobe -rv ssb
sudo modprobe -rv brcm80211
sudo modprobe -rv brcmfmac
sudo modprobe -rv brcmsmac
sudo modprobe -rv bcma
sudo modprobe -rv wl
sudo modprobe -rv btusb

Once you resume, run the following commands:

sudo rfkill unblock wifi
sleep 3
sudo modprobe -v brcmfmac
sleep 1
sudo ip link set wlp3s0 mode default
sleep 1
sudo ip link set wlp3s0 up
sleep 1
sudo systemctl start NetworkManager
sudo nmcli networking on
nmcli r wifi off
nmcli r wifi on

These commands should hopefully successfully restart your WiFi after resuming. Bluetooth will not be restarted with the above commands to see if that also helps. If you wish to restart your Bluetooth afterwards you can run sudo modprobe btusb.

As always, please post both the full input and output of all commands run.

Good luck.

Thanks for the lessons. When I wrote my does not work, it was in fact after I did inspect everything in minute detail. I am not new to computing. I appreciate the reminder though.

It does in fact work. All I had to do to get it working was shutdown and restart and lo-and-behold, the network service now nicely figures out it is down, starts up again, and writes me a nice notification after re-connecting.

So this is a slick thing to do, adding a network-restart service. Learned something valuable there.

Thanks!

Glad to hear you got things working.

For the benefit of others with a BCM4360 WiFi adapter, please post the working version of the service you are running.

That way Broadcom users with Wifi adapters that require the brcmfmac driver have a working service example to refer to.

Personally I’d avoid buying Apple products if you intend to run Linux in the future. Apple and Broadcom adapters especially are notoriously hard to get working properly under Linux. Just a word to the wise, but do as you please YMMV.

Absolutely correct, what you say about new Apple products. Old apples that are no longer supported are ideal for Linux thanks to their advanced hardware at the time. I would like to emphasize that Apple products are recyclable thanks to Linux.
My mission is to breathe new life into old Macs and give them away.

It is an old machine from 2015 that I am resurrecting with Linux as a fun project. I am not buying a NEW Apple machine and trying to fit Linux onto something that will surely be something crazy cutting-edge!!

I was figuring that since this laptop is nearly 8 years old, it would slot nicely into most *nix kernals without too much trouble, as many hundreds if not thousands of others before me would’ve worked out the kinks!

It has always been a challenge getting Linux working! I was doing it when the Intel 386SX and first generation 486 chips were state of the art…

Anyway, the service is the one you suggested, word for word with the only edit needing to be the swapping out of the brcmfmac.

I think my model, the MBP 12,1 is one of the best they ever made! Heavy sure, but it is has ports, a nice screen and decent performance. Ideal for Linux in 2023!

Again, pease post your working solution.
