I just received a new MC7304 card to put into my Ubuntu 14.04 Server. I am replacing a USB Huawei stick which worked reasonably well via wvdial and PPP. I managed to get the MC7304 connected via wvdial and PPP after setting the correct /dev/ttyUSB2. I am now looking at using the QMI interface since it is supposed to be faster. I installed the libqmi-utils package to get qmicli and qmi-network. I then followed a gist I found on how to conenct via this on Debian. However after connecting the wwan0 interface does not get assigned and IP and dhclient does not get a response either. How should I configure it? Ideally I want to set it into /etc/network/interfaces so it will connect at boot. I am on Ubuntu 14.04 Server. Here is the output from dmesg: ```auto [2.489035] usb 1-5: new high-speed USB device number 4 using xhci_hcd [2.516771] usb 1-5: config 1 has an invalid interface number: 8 but max is 5 [2.523818] usb 1-5: config 1 has an invalid interface number: 10 but max is 5 [2.523819] usb 1-5: config 1 has an invalid interface number: 11 but max is 5 [2.523826] usb 1-5: config 1 has no interface number 1 [2.523829] usb 1-5: config 1 has no interface number 4 [2.523833] usb 1-5: config 1 has no interface number 5 [2.576398] usb 1-5: New USB device found, idVendor=1199, idProduct=68c0 [2.582571] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [2.588829] usb 1-5: Product: MC7304 [2.588831] usb 1-5: Manufacturer: Sierra Wireless, Incorporated [18.452576] usbcore: registered new interface driver usbserial [18.452586] usbcore: registered new interface driver usbserial_generic [18.452592] usbserial: USB Serial support registered for generic [18.505217] usbcore: registered new interface driver cdc_wdm [18.505386] usbcore: registered new interface driver qcserial [18.505405] usbserial: USB Serial support registered for Qualcomm USB modem [18.512255] qcserial 1-5:1.0: Qualcomm USB modem converter detected [18.512337] usb 1-5: Qualcomm USB modem converter now attached to ttyUSB0 [18.520279] qcserial 1-5:1.2: Qualcomm USB modem converter detected [18.520336] usb 1-5: Qualcomm USB modem converter now attached to ttyUSB1 [18.525646] qcserial 1-5:1.3: Qualcomm USB modem converter detected [18.525710] usb 1-5: Qualcomm USB modem converter now attached to ttyUSB2 [18.557315] qmi_wwan 1-5:1.8: cdc-wdm1: USB WDM device [18.557904] qmi_wwan 1-5:1.8 wwan0: register 'qmi_wwan' at usb-0000:00:14.0-5, WWAN/QMI device, 32:d8:ac:1b:14:11 [18.560861] qmi_wwan 1-5:1.10: cdc-wdm2: USB WDM device [18.561186] qmi_wwan 1-5:1.10 wwan1: register 'qmi_wwan' at usb-0000:00:14.0-5, WWAN/QMI device, 32:d8:ac:1b:14:11 [18.562097] qmi_wwan 1-5:1.11: cdc-wdm3: USB WDM device [18.562195] qmi_wwan 1-5:1.11 wwan2: register 'qmi_wwan' at usb-0000:00:14.0-5, WWAN/QMI device, 32:d8:ac:1b:14:11 [18.562222] usbcore: registered new interface driver qmi_wwan ``` Here is output from qmicli: ```auto [/dev/cdc-wdm1] Successfully got system info: GSM service: Status: 'none' True Status: 'none' Preferred data path: 'no' WCDMA service: Status: 'available' True Status: 'available' Preferred data path: 'no' Domain: 'cs-ps' Service capability: 'cs-ps' Roaming status: 'off' Forbidden: 'no' Location Area Code: '32200' Cell ID: '196610508' MCC: '505' MNC: '02' HS call status: 'hsdpa-hsupa-unsupported' HS service: 'dc-hsdpa-plus-hsupa-supported' Primary scrambling code: '44' Cell broadcast support: 'off' Call barring status (CS): 'all-calls' Call barring status (PS): 'all-calls' Cipher Domain: 'none' LTE service: Status: 'none' True Status: 'none' Preferred data path: 'no' SIM reject info: 'vailable' ``` Here are the commands I tried to use to connect: ```auto leith@server:~$ sudo qmi-network /dev/cdc-wdm1 start Loading previous state... /usr/bin/qmi-network: 72: /usr/bin/qmi-network: source: not found Starting network with 'qmicli -d /dev/cdc-wdm1 --wds-start-network= --client-no-release-cid'...
