"No WWAN Adapter Found"

Librem
1

Hello,

I’ve been getting a No WWAN Adapter Found error on my L5 for some time now. I never made a complaint here because I thought it would be fixed in the andrecent upgrades, but it still doesn’t work.

I’ve always had the same SIM in the slot. I’ve tried rebooting over 10 times now and toggling the kill switches, but still nothing. Everything else works fine, though.

Note: I don’t use the phone as a daily driver yet and haven’t tweaked anything on it. It’s still in its new/factory state. I’ve just been turning it on and updating it now and then and maybe a little light web browsing here and there. I also have a working SIM in it and make a few texts and calls sometimes to see if the phone itself continues to work properly.

Any recommendations on what I could try? Thanks in advance.

This is what I’m seeing in relation to the wwan in output if it helps

Check Settings -> Privacy -> Screen lock. Is “Forbid new USB devices” selected there?

4

Nope. It’s disabled.

5

“mobile data” enabled or disabled?

6

What do you mean? Is that a setting somewhere?

When I click Settings -> Mobile there are no options. Just a splash screen that says “No WWAN Adapter Found”.

@dos any word on this? Even if I wanted to sell my phone, I cant because the wireless adapter just stopped working after an upgrade. I havent customized anything on the phone. It just stopped working. :frowning:

8

What’s the output of sudo usbguard list-devices with the modem turned on?

@dos sorry for the late reply. I was out of town. Here’s the output:

What kind of network are you trying to use? Also, which modem variant do you have?

This shows that it’s trying to use CDMA-EVDO and it seems that the provider rejects the activation. CDMA providers are not supported.

Oh I see. That’s odd because this is the same provider/SIM that I’ve always used in the phone. Are you sure that’s the issue though? Why would it tell me that there is “No WWAN Adapter Found” if there actually is one? Shouldn’t that error message say something like “SIM doesnt work for provider” or something similar?

14

They might’ve recently caught on, some internal audit or something.

15

Because actually there isn’t one. :wink:

Yes, the error messages could be more helpful.

A lot of things have to work in order to make use of the mobile network.

  • modem :heavy_check_mark:
  • SIM
  • registration with the mobile network
  • creation of devices and interfaces on the Linux side
  • bringing up the interface e.g. getting an IP address (in the case of mobile data)

Based on what you have posted so far, only the first thing is confirmed.

I would guess you are falling down on the third thing. The error message I think is complaining about the fourth thing (which by definition can’t work if the third thing hasn’t worked).

As far as the SIM goes, if you have another phone to test with, you could verify the SIM in that other phone i.e. shut down your Librem 5, remove the SIM and try it in another phone.

It may help to mention what country you are in and what mobile service provider you are using (in addition to the modem variant).
