Have a good read through the Arch Wiki pages about USB 3G modems and Huawei E220. Your specific model is discussed in the forums which suggests the following: Create /usr/share/usb_modeswitch/12d1:14db with the following content # Huawei E303 DefaultVendor = 0x19d2 DefaultProduct = 0x14db TargetVendor = 0x19d2 TargetProduct = 0x14db MessageContent = ...

The CUA devices are both serial ports. 3G modems have often 1 to 3 serial ports. One of them is the communication port and the rest are control and monitor ports that you can use for e.g. checking the signal level (with AT commands) while connected. The first port is almost always the communication port that you should use. You can see if dmesg gives any ...

[EDIT] I found a post with instructions - I'm not sure how current that is. It looks like you use Puppy's own Internet Connection Wizard (launched by an icon labeled "connect"), which has an option "Internet by dialup analog or wireless modem". That shows PupDial, which can be used to establish a connection using your modem. Below is a description about how ...

The recommended approach would be to have udev start a systemd service, which itself depends on your device. The service file should look something similar to the following. my.service - to be placed in /etc/systemd/system/ [Unit] Description=<DESCRIPTION HERE> BindsTo=<DEVICE UNIT HERE>.device After=<DEVICE UNIT HERE>.device [Service] ...

Possibly, your 3G provider gives you a private IP address from one of these ranges 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 In this case, you're behind ISP's NAT and can't access Pi from the internet, but you can access the internet from Pi.

Whatever's talking directly (at layer three) to the provider gets the address the provider assigns, which is usually global. Though, if you connect a Linux box directly to a modem, then that's it.

There are ways to start a script every time a particular interface goes online. Where they are depend on your distribution (please specify). There is also an easier option (which may or may not work), the "Use VPN..." option in the NetworkManager (Edit Connections menu). Are you using this last option and it does not work? Depending on what you use to ...

I suggest you first try another your computer in another place, preferably closer to the cellphone base station, and see if the reception is better from there. That should give you an indication whether the device malfunctions or not. (Don't get directly beneath the providers antenna's, my experience is that you can get bad reception there). Obstruction of ...

Dell branded Sierra Wireless modems, like the 5570 (bought one myself now) need a magic "DMS Set FCC Auth" command to recover from low-power mode, better explained here: https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/ If you're using ModemManager, you can try to compile your one libqmi and ModemManager from git ...

You're lacking the APN in the --wds-start-network option. You wouldn't need it if you were in a CDMA/EVDO network, but it is (usually) required an explicit one in GSM/UMTS/LTE. Once QMI WDS Start Network returns with no error, just try to run dhclient in the WWAN interface.

By some trial and error, I found following section in my /etc/ppp/options: # BSD licensed ppp-2.4.2 upstream with MPPE only, kernel module ppp_mppe.o # {{{ refuse-pap refuse-chap refuse-mschap # Require the peer to authenticate itself using MS-CHAPv2 [Microsoft # Challenge Handshake Authentication Protocol, Version 2] authentication. require-mschap-v2 # ...

I had a similar problem. I found out that the the GSM modem ISP blocks all incoming traffic. I read that you can pay the ISP extra to permit incoming traffic. I only wanted to ssh to the RPi over GSM. A reverse SSH tunnel was the solution. I don't know how to solve your problem. But at least I can provide a hint to the cause of it.

The new version of Chromium OS offers the UMTS feature. So the problem is solved now.

That log looks like the effect I get from pulling out a USB drive without unmounting and reinserting. Doing that also remounts the USB on new device number. Your 3G modem probably has a build in storage (for the (windows) driver), so if this happens without you taking the the modem out, it could indicate bad contacts on the USB connector or an almost broken ...

Yes, will be supported in ModemManager/NetworkManager, either via AT+WWAN or even via MBIM through libmbim. ModemManager has several H5321gw flags for different VID/PIDs already, but if yours end up being shown with a different pair, just post a new bugreport to ModemManager to get it added properly.

That FRU# 0A36319 is actually a Ericsson H5321gw card. Looking around this card does appear to be supported, but there are different revisions of the hardware and so they typically change the USB ID of the revisions slightly so you may need to add your particular version to ModemManager so that it's recognized. ThinkWiki page on W530 Issue with USB ID ...

Solved the problem. First generate the wvdial.conf file using sudo wvdialconf. Change your user name, password and Phone number in /etc/wvdial.conf file. Then run wvdial. Dongle will connect in broadband mode.

I've managed to make device detectable as modem by force switching it into "only modem" mode: find the appropriate modem TTY ls /dev/ttyUSB* (usually ttyUSB0) connect minicom to modem minicom -D /dev/ttyUSB0 send command AT^U2DIAG=0 (only modem mode) unplug and plug modem again, you can see your mobile wireless connection in Network ...

You can delete related profile file under /etc/NetworkManager/system-connections for LinuxMint. More info: http://superuser.com/questions/517678/how-can-i-reset-all-network-settings-in-linux-mint

Web search suggests this modem knows AT command set, so you can easily check this using "tip" or "cu" commands with both ports and detect which one responds to AT.
