Help setting up a router with sim card

Hi, I have a D-LinkDWR-921 c3 and I want to use the lte modem in it, the wiki does have a guide for setting that up but i run the commands and still get no network access. Any help would be appreciated

I have set up that router, currently using the "Play" service provider in Poland, but it also worked seamlessly with other providers in the past.

Please provide answers to the following:

  1. Which guide did you follow?

  2. Are you using the QMI mode for the modem?

  3. Can you provide the output of uci export (removing any passwords you might have in there)?

What commands and what is the output of those commands?

• 
uci set network.wwan=interface
uci set network.wwan.proto='qmi'
uci set network.wwan.device='/dev/cdc-wdm0'
uci set network.wwan.apn='YOUR_APN_HERE'
uci commit network

uci set network.wwan.autoconnect='1'
uci set network.wwan.delay='5'
uci commit network

uci set firewall.@zone[1].network='wan wan6 wwan'
uci commit firewall

ifup wwan

opkg update && opkg install luci-proto-qmi

reboot

there is no output and the wwan interface starts and crashes and restarts in a loop
