DW5570: how can i use the WWAN under High Sierra?


Recommended Posts

Sorry, but I see we entry in precise specification technical, but I'm not an electronics technician.

Hmm...Do I think good? I must "plug off" pin 20 (on modem), that my modem would be in ONLINE mode?


I hope that in soon it will be explained if it will be online mode or I'll must buy other model.

No need to be an electronic engineer... Simply put a small and narrow piece of cellotape (or any other type of self-attaching masking tape) over the entire pin 20 of your card to entirely isolate it. Do you follow? You can Google for pin 20 if you need further illustration.


It would be quite a challenge to place the properly-sized piece of masking tape over pin20 only, so apply wider-than-required piece of tape on your card, then use a small cutter to remove the excess parts.
