USB Modem

[Thermostaten]

On the older Tetra i could use my Sierra Aircard modem out of the box.

When I made a SSH connection to the Pineapple Tetra and ran ifconfig -a then i could see it as wwan0

I only had to 

vi /etc/config/network

option ifname 'wwan0' # add this line under wwan

and

vi /etc/config/dhcp

option ignore 0 # set this under under wan

Then it worked. 

But here on the Pineapple VII i cant see the card

What opkg update && opkg install xxx do i need ? I cant find kmod-usb-net-sierrawireless kmod-usb-serial-wwan kmod-usb-serial-sierrawireless kmod-usb-serial-qualcomm or anything that would make the card work ( like opkg list|grep -i sierra )

Any hints ?

What does "lsusb" show, when the device is connected?

Also please run dmesg after connecting the modem, an post the output.

[Thermostaten]

The card is called AirCard 320U BigPond ( a qualcomm chip) 3G
The ttyUSB does not appear - but the SD card on the modem is shown

@Thermostaten 
hi,

may I ask you for an update on this topic? Did you end up with working USB modem?

Regards,

kakadoo

As an alternative to a USB "modem", it's possible to use a mobile USB router. I use my Huawei E5377 with the Mk7 connected via USB. If I remember correctly, the following packages are needed for that specific scenario:

usb-modeswitch
kmod-usb-net
kmod-usb-net-cdc-ether

However, it's easier to use the AP of the mobile router (or use the hotspot of my phone) instead of connecting cables.

[Thermostaten]

I think i ended up with this My Pineapple Nano with the modem and got it to work: 

 

#opkg install wwan guide pineapple wan sierra u320 air

opkg update

opkg install usb-modeswitch kmod-usb-net-cdc-ether

# vi /etc/config/network

option ifname 'wwan0' # under wwan

# vi /etc/config/dhcp

option ignore 0 # under wan

 

[exec4]

This should now work on the MK7 with Firmware 1.1.0 too.
