GL MiFi EU Roaming Proximus does not connect

hallard · 2019-10-09T13:23:45.641Z

I’m using French card on French country on my GL Mifi router. All is working fine.

But I spend lot of time trying to understand why another card is not working.
my Proximus (belgium operator) with EU roaming does not works in France, unable for the 4G modem to connect, if fact it detects operator (SFR) but does not connect.
If I’m using the same card on Teltonika router or Comfast CF-E5 (which as a qecktel EC25 modem also) everything is working fine.

So the issue is coming from firmware, I tried 3.023 and pre release 3.026 and it’s the same issue.
May be it’s related to this case ?

FS#1252 - No IP Assigned to Interface with QMI on Quectel EC-25A

*johnfzc:* I'm attempting to use QMI on a GL.Inet MiFi equipped with a Quectel …EC-25A cellular modem. When I configure the interface using qmi I am able to connect to the cellular network at the radio layer, however my wwan0 interface is not assigned an IP address. Here's my configuration from /etc/config/network: config interface 'modem' option proto 'qmi' option ifname 'wwan0' option device '/dev/cdc-wdm0' option country 'country11' option apn 'inet.bell.ca' And some commands showing the device behaviour. You'll note that raw_ip needs to be set to Y. I've integrated this [patch](https://github.com/bmork/LEDE/commit/10aed12fa587e818e4dc5d0db54545623fbe9b5f) to have qmi.sh set the raw_ip mode when required. root@OpenWrt:~# cat /sys/class/net/wwan0/qmi/raw_ip Y root@OpenWrt:~# ifup modem root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-data-status "connected" root@OpenWrt:~# uqmi -d /dev/cdc-wdm0 --get-current-settings { "pdp-type": "ipv4", "ip-family": "ipv4", "mtu": 1500, "ipv4": { "ip": "100.105.180.51", "dns1": "206.47.201.246", "dns2": "207.231.231.254", "gateway": "100.105.180.52", "subnet": "255.255.255.248" }, "ipv6": { }, "domain-names": { } } root@OpenWrt:~# ifconfig wwan0 wwan0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet6 addr: fe80::d789:480e:bfc8:2dac/64 Scope:Link UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:28 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5129 (5.0 KiB) TX bytes:768 (768.0 B) If I manually use the uqmi command to connect to the cellular network I can then drive the wwan0 interface using dhcp successfully.

Any help would be appreciated

We should have fixed the BUG in your link
Are you using ec25-e modem?
Does the Teltonika router use the same modem?

Nice to hear that, which version should I test? Because latest stable and latest pre release does not fix it. I can ssh to device and do some testing if needed.

Teltonika does not have the same modem, but the COMFAST has an EC25-E modem (mini pcie) and the card is working fine on it.
