## Check for QMI modem
Check if a device has been recognized as /dev/cdc-wdm0:
```
ls /dev/cdc*
cdc-wdm0
```
Check if the device is detected:
```
cat /sys/kernel/debug/usb/devices
```
If the device is already in QMI mode you can proceed with
the installation of the kernel module.
## Install USB QMI Kernel module
```
apk update
apk install kmod-usb-net-qmi-wwan uqmi luci-proto-qmi
```
Reboot the device, so everything gets loaded.
## Setup the OpenWRT interface LuCI:
Go to "Interfaces"
Click on "Add"
Select "Protocol" -> "QMI Cellular"
Add "Device" -> "wwan0" or "/dev/cdc-wmd0"
Set "Firewall Settings" to "wan"
### For Aldi Talk only
APN = "internet.eplus.de"
Authentication Type = "PAP"
username = "eplus"
password = "internet"
And don't forget your SIM pin if one is set.
