Modem woes and reliability

i have firmware

m100E_YCSN0_1.0.0_220926
YCSN0_M100E_1BAD_3117_V1.0.0.2_20220930
M100E_1.0.4_200715

is that the latest or is there a newer version? because it looks like 2022 software

If it helps, I updated my firmware to:

M100E_YCSN0_1.0.0_220926
YCSN0_M100E_1ACD_B325_V1.0.0.2_20220930
M100E_1.0.4_200715

thanks seems i’m running the latest. Support also confirmed that.
Going to take the steps i got from support.

But this sort of supports my post, we are running the latest. but the modem is stil pretty unstable. firmware seems to be from at least a year ago

that sort of supports my feeling that it doesn’t get the priority it should get. Maybe the work needs to be done outside the firmware, i don’t know i haven’t delved into the nuts and bolts.

Also the latest update i pulled saw the mobile settings app getting updates (in example). Which is nice, but not critical to the base functionality of a phone.

Like i stated before: i would not trust the librem5 with my life nor with receiving critical calls. That is something i never had with a phone, and i still trust my 10year old windows phone.

that is the problem with the linux phone space at the moment. I really hope that can be fixed because at least for me, that is the 1 critical issue keeping the linux phone space from becoming my dialy trusted device

I just got mine back from repair. It was wiped of course but now I’m having all kinds of trouble with the modem and wifi. I was able to connect to my provider yesterday, but today in no ways of trying I cannot connect at all in fact it’s trying to connect to other carriers not mine. I confirmed that my SIM works in my Samsung phone so has nothing to do with the provider. Also the WiFi is now anoyingly randomly shutting down and not reconnecting for some reason. I love this phone but like you this part of it needs top priority all hands on deck to try and solve.

Did they replace the modem? (so that the IMEI changed)

Updating to the latest Redpine firmware solved my WiFi problems.

For the modem problems, I created a script at /usr/local/bin/resetmodem with the content:

mmcli -m any --reset
service NetworkManager restart

I made it executable: sudo chmod +x /usr/local/bin/resetmodem

Then I execute sudo resetmodem from the terminal. I’m thinking about setting it up as a cronjob and executing it every couple hours.

I believe they did but my phone was working fine the first day I got it back, so not sure it matters. Also with my provider (who I actually work for) I’ve changed my SIM into different phones many times without issue.

Also why is it I can’t select a network manually in the settings app? Should it not display all the available networks?

I have a sparklan card.

I have been wondering about this too.

I tried doing this with the command line as well and it does not reveal the available networks with a scan. Which makes me wonder how it even finds networks. I’m having a very weird problem with my phone. So it registers with the network in town where I work but as I travel home about 50 km away it loses registration even though it is still on the home network or should be. My SIM works fine in other phones so it’s definitely the L5. The errors I’m getting in the journalctl is “reject cause: roaming-in-location-area-not-allowed” and “ps-services-in-location-area-not-allowed”

It doesn’t make much sense to me because the phone works in one area but not another? The same network is available but the phone thinks it’s roaming I think. When it’s searching for an operator it gives errors “Current operator MCC/MNC is still unknown” which makes no sense because it works in town but not at home. I also tried enabling roaming and that didn’t help either.

Does anyone have any ideas what could be going on here?

Today, again, out shopping, I had to HKS the cellular modem to be able to check something online - leaving me to wonder how long I had been online by that time.
I get the impression it has something to do with switching antenna’s. (Just a stab in the dark.)

All and all, this happens too often, and it is becoming an irritant. Pioneering the L5 is an adventure, but it would be nice if the absolute basics (the phone bit) would have been covered by now.

Yes! Also bloody annoying: every single time you reset the modem, the yellow exclamation mark pops up, and you have to disallow/allow the roaming option in the settings.

try with volte disabled and see if the modem is more stable.

Yeah I tried that per support but it was just as messed up. I’m going to reflash to see if something is just wrong with the flash they did before sending it back.

indeed. In all honesty, this should have the top prio. without this there is no phone and no trust in the device (at least for me)

the rest seems mostly fine (except firefox addons screenflicker/problems which makes addons pointless), so improvements should be put on the backlog until the critical modem bit is fixed.
Pinephone with mobian has the same type of issues.

Also today:

  1. phone was empty in the morning and shut down after reboot:
  • no modem/gsm
  • mmcli -m any --reset -> error couldn't find modem
    
  • killswitch did not work
    

10-15 minutes later the modem reappeared

  • i tried the mmcli -m any --reset again
  • modem was found and reset, but doesn't show in the UI. seems to take a long time to get
    
  • killswitch no result
    
  • back 5-10 mins later
    

2 hours later

  • phone is on the charger
  • no sim ui icon
    
  • mmcli reset modem takes a long time before it reappears
    

In the afternoon:

  • my family can’t reach me again because nothing rings/registers.
    i collected the logs and will mail support but this is a mayor hindrance to this becoming viable

I don’t have an answer for this modem reliability trouble, but am thankful that you are posting about it. I sold my Librem 5 a couple years ago because it was not ready to be my daily driver for many reasons, and I follow the project once in a while on here to see how it’s going. I really want it to succeed so there is a follow-up model that I could buy and use full time. Your mention of your old Windows phone resonated with me because no smart phone has come close in my experience to the excellence of their keyboards and predictive typing and spell check. And other things. My family and I still talk about how great they were compared to the Androids and iPhones we migrated to years ago. I’d be delighted to have a Linux-powered computer in my pocket that had the interaction design and UI of Windows Phone 8 but FoSS underneath. I wish you well getting your modem to work better.

I was actually recently thinking of writing/posting to microsoft. Just to float the idea that maybe microsoft should try to make a new phone, or just throw its weight behind the linux phones. I mean we really need a good alt to the google/apple duopoly

Just imagine a linux phone as stable as those windows phones made by nokia. With easy interop with both linux and windows desktops. Maybe get some of that accessible .net programming support for super fast app dev.

Personally the biggest problem with the windows phones was the sudden shift/restrictions in .net development. Microsoft was emulating apple and google instead of just doing a windows desktop with calling thing.

Developing for those phone was a just horrendous. I love programming in .net and i just hated all the forced restrictions of async and the terrible UI xml stuff. that is why the software lagged i think.

When i compare that to how easy it is to develop stuff for the linux phones so far. i think that is where they failed and the linux phones can succeed. There is so much choice to develop with, gtk, python, java, .net, it’s all good. just pick your favorite

I’ve also received my second L5 back from the EU repair center.
The symptoms you describe are more or less the same as I am struggling with.
Modem connectivity is most of the time a no go.
No Mobile network detected or if detected, unable to connect to any site, or falling back to 2G, or staying on 4G while not registering on the provider network. Toggling all buttons (roaming on/off or Mobile data on/off, or HKS) Most of the time it does not change things.
Strange enough, sometimes I do get a working connection but that will be over after the L5 switches to idle (screen off, no suspend).

Did you re-flash the phone and did it improve things?

Totally WRONG. :wink:
