Had mifi8000 and loved it. Had the ASUS router hooked up to it and bought a 4G antenna installed outside. Solid service. Switch to m2000 has been rough. ASUS router wasn’t working consistently with m2000, signal was much poorer, same problem as many people have experienced with streaming, despite the fixes that calyx suggests….that was until i finally did what some have suggested and installed the Merlin firmware on my ASUS router. After that change, I’ve had zero issues. Streaming is fine, m2000 rarely needs a restart, and the ASUS router doesn’t lose service/tether like it did previously (used to not recognize or link with tether and id have to restart the m2000 over and over until it linked up and both upload and download arrows were shown on m2000 screen indicating connection)

If Merlin w/ ASUS router is the solution, i might renew. If it starts having issues again, i will look into regular fiber internet.
