Hi all,
I've installed the latest OpenWrt version on my Xiaomi Mi 3G router and it works perfect. I would like to add my 4G Huawei E5785lh to the USB port and found several guides on how to do this via the Huawei-cdc-wdm mode.
I got the wwan0 additional interface and configured this for as DHCP client to get the IP from the Huawei, however the errors are shown in the logs:
Sun May 5 19:03:22 2019 daemon.notice netifd: Interface 'lte' is now down
Sun May 5 19:03:22 2019 daemon.notice netifd: Interface 'lte' is disabled

Sun May 5 19:03:29 2019 daemon.notice netifd: lte (10044): udhcpc: sending discover
my /etc/config/network looks like this for the lte interface:
config interface 'lte'
option proto 'dhcp'
option ifname 'wwan0'
option metric '100'
dmesg log shows the following:

Could one of you help me with this? I think I came quite far, but in the end I got stuck.
Many thanks in advance.
