Hi there!

I’m running DD-WRT v3.0-r49544 std (07/22/22) on a Netgear R6300v2. I’m trying to get the USB modem ALFA Tube-U4G to play nice and according to the supported modem-list it should be supported (Vendor=2c7c ProdID=0125 aka Quectel EC25).

Using another USB modem, Huawei E173u-1 (12d1:1436), the setup works flawlessly, but E173 only supports 7.2Mbps and we need the speed of 4G/LTE.

Looking at debug, I’m seeing more or less the same as depswa in this thread with the exception that I’m not only seeing device detection but also getting ttyUSB devices created - but no connection.

Looking at ppp; /tmp/ppp/options.pppoe is identical with depswa's and /tmp/comgt.out contains:
stty: standard input: Not a tty
Can't open device /etc/comgt/dial.comgt

Any pointers on how to proceed would be very much appreciated - should I play around with usb_modeswitch? Even though depswa did have progress with usb_modeswitch I got the impression the actual solution was a change in lib3g?

Debug follows below

Hi there!

Any pointers on how to proceed would be very much appreciated - should I play around with usb_modeswitch? Even though depswa did have progress with usb_modeswitch I got the impression the actual solution was a change in lib3g?

//Mattias


The 2 Quectel modems which are supported according to the wiki list did for some reason never get into lib3g.. Rolling Eyes

I'll add them and send Brainslayer the updated source in a day or two.

Hi LOM,
as far as pointers/response to a question go - that's about as good as they get. Thanks a million!

Nice! Very much appreciated and thanks to all involved!

Tried todays build (r49599) and the modem now connects according to the GUI. Also reports signal strength Smile

However, I get no WAN IP.

Used qmi to check status and got informed it was disconnected. Tried to connect it manually:

Code:
root@DD-WRT:~# uqmi -d /dev/cdc-wdm0 --get-data-status
"disconnected"
root@DD-WRT:~# uqmi -d /dev/cdc-wdm0 --start-network internet --autoconnect
-2026896544
root@DD-WRT:~# uqmi -d /dev/cdc-wdm0 --get-data-status
"connected"


Success! But still no IP in the webGUI, however. And still no connection to internet - also verified by using a client to try to connect to internet. Checked nvram, see nothing odd:

Code:
root@DD-WRT:~# nvram show | grep 3g
size: 37900 bytes (27636 left)
3gcontrol=qmi
3gdata=qmi
wan_proto=3g
wan_3g_signal=RSSI: -63 / RSRQ: -9
wan_3g_mode=lte

Checked routing and wwan0 is not present.
Code:
root@DD-WRT:~# ip route
127.0.0.0/8 dev lo scope link
192.168.1.0/24 dev br0 scope link  src 192.168.1.1

Anything from the modem? Yes, this looks promising - the modem seems to think it has an ip (it's an internal ISP IP, but that's probably ok)
Code:
root@DD-WRT:~# uqmi -d /dev/cdc-wdm0 --get-current-settings
{
   "pdp-type": "ipv4",
   "ip-family": "ipv4",
   "mtu": 1500,
   "ipv4": {
      "ip": "100.89.211.205",
      "dns1": "2.248.248.101",
      "dns2": "2.248.248.100",
      "gateway": "100.89.211.206",
      "subnet": "255.255.255.252"
   },
   "ipv6": {
      
   },
   "domain-names": {
      
   }
}


Looking at wwan0 it does not get an IP though

hw adress of wwan0 matches the USB device that was registered as QMI

Code:
qmi_wwan 1-2:1.4 wwan0: register 'qmi_wwan' at usb-0000:00:0b.1-2, WWAN/QMI device, b2:9e:58:44:1e:be


My naive analysis is that the modem is connecting to the ISP but there is something lacking in the interface between the modem and dd-wrt router.

Any ideas?

What port is assigned to WAN on the Setup -> Networking tab?

It looks like the EC-25 uses raw_ip protocol.

See: https://forum.openwrt.org/t/openwrt-and-qmi-mode-lte-quectel-ec25-e-raw-ip/97680

Can you get it working by manually flag it for raw_ip in the sysfs?

Thanks LOM, that seems to do the trick.

For reference:
Code:
root@DD-WRT:~# cat /sys/devices/pci0000:00/0000:00:0b.1/usb1/1-2/1-2:1.4/net/wwan0/qmi/raw_ip
N
root@DD-WRT:# echo "Y" > /sys/devices/pci0000:00/0000:00:0b.1/usb1/1-2/1-2:1.4/net/wwan0/qmi/raw_ip
root@DD-WRT:# cat /sys/devices/pci0000:00/0000:00:0b.1/usb1/1-2/1-2:1.4/net/wwan0/qmi/raw_ip
Y


Must be done with wwan0 removed (ifconfig wwan0 down), otherwise the error "sh: write error: Resource busy" appears.

Code:
root@DD-WRT:~# ifconfig wwan0
wwan0     Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 
          inet addr:100.91.177.182  P-t-P:100.91.177.182  Mask:255.255.255.252
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:110069 errors:0 dropped:0 overruns:0 frame:0
          TX packets:111968 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:113326330 (108.0 MiB)  TX bytes:111265696 (106.1 MiB)



WAN IP is correctly showed in webGUI and connection is working lika a charm.

Code:
root@DD-WRT:~# ip route
default via 100.91.177.181 dev wwan0
100.91.177.180/30 dev wwan0 scope link  src 100.91.177.182
127.0.0.0/8 dev lo scope link
192.168.1.0/24 dev br0 scope link  src 192.168.1.1


The change does not survive a reboot. Tried to create a "lost signal" scenario to see if the change survives but the modem antenna is just too damned good.

I'm guessing startup commands could solve the issue of the changes not surviving reboot? Are there any other possible solutions to make the setup more robust (not require manual setup)?

Yes, I have asked Brainslayer to flag all the Quectel cards I added support for as QMIRAW instead of QMI so should work automagically in next released build.

Thanks, that sounds to me like a very robust setup/solution Smile

Its perfectly normal to be unable to configure interfaces while they are in use via CLI, so as you noticed you need to send interface down, config and send interface up.

In addition and for immediate persistent benefit, in order to survive reboots and clicking the apply button, feel free to use the Administration tab/Commands sub-tab and save the config as Firewall. This will run then at every reboot and when clicking apply where services are restarted and interfaces go down and up.

Obviously you need to send the interface down, inject the config and send interface up in this scenario.

It will work.

Will be fixed in the next release. Thank you for all you do, LOM!
