Huawei E397

Hwurzburg

I got this stick modem and intially, it worked fine and connected to my network....a few days later, it seems to get assigned an address from my provider but there is no communication into the network....
I can move the modem to my PC, and using the included utility, make it connect and work...

it just keep flashing its connection light (it turns solid on the PC after I have the utility say connect)
here is the interface config from the RPI:

wwan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 169.254.235.255  netmask 255.255.0.0  broadcast 169.254.255.255
        inet6 fe80::bec8:f3bb:26a4:ae5b  prefixlen 64  scopeid 0x20<link>
        ether 56:9f:aa:ab:5e:37  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 34  bytes 5582 (5.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

so it seems not to be getting a subnet address...usually 100.x.x.x
the UAVCast web gui says everything is good, and I can connect via the wifi interface to the flight controller, but if I kill WIFI to run on the cellular, the RPI is isolated from any network...ie no data is flowing on the E397
I dont understand why it worked before, works on the Pc, but now has stopped working with RPI

Hwurzburg Hi
Could you please post the interfaces after you have pressed connect in the web gui.
Also, could you provide an image covering your configs in web gui.

Does it say connected in the UAvcast?

I found out that my modem's light blinking means it sees the cellular network signals, but not yet connected..
thanks

Hwurzburg Are you sure APN name pwg is correct?
Who is your carrirer?

Hwurzburg

yes USMobile https://www.usmobile.com/help/knowledge-base/configuring-your-device/#ics-jb-kk
I use it when connecting with my PC using this modem

Sinamics

Hwurzburg could you try to type sudo nmcli r wwan on in a terminal, and let me know the outcome. I would like to connect your rpi myself and have a look using Team viewer. Im available later today.

Hwurzburg

accepted command , no output...no change to modem status....all green lights in web gui
I would be happy later today to have you log in...do I just install teamviewer from their website?

Sinamics

Hwurzburg yes, just install the free version from their website. I'm available in two hours time. Press the chat link above and send me the id and password in a PM
