Using an LTE modem on my router

Mar 2, 2018
Hey guys and gals. My router has a USB port for 3g/LTE failover. And ever since I reset the router I'm not getting any internet access.

I tried fiddling around in the settings to find out why there was no internet access earlier today, only to later find out that our ISP, Telkom, has had network problems.

Now the WAN service I initially setup is gone and I can't recall how I got it to work in the first place.

Router model: DLINK TELKOM DSL-G2562DG
LTE Modem: D-LINK DWM 222

Any help is very much appreciated.
