I noticed that on the back of my router there are 4 led under the nomination of WAN:

I didn’t realise I can connect the router to Internet via WiFi ? SIM1/SIM2 I understand. Same for Ethernet WAN connection but how is it done via WiFi?
How do I connect WAN via WiFi?
So I watched it and it is a bit confusing since they are connecting a RUTX to a RUTX. A bit unclear which router is sending and which router is receiving…
What if I connect a RUTX50 to a hotspot of an iPhone or WiFi network of another router (Not RUTX)?
Follow the guide from 1:10 should work
I will give it a try. Thanks!
