inseego FW2000e and Asus router NO INTERNET

It could be you have a router that has a problem. When working in IT for years I came to the conclusion that when the problem defies logic it is often hardware. That can often be the case. I have no way to confirm you have a hardware issue with the FW2000E but if problems from the very start are present and continue that makes me suspicious of the hardware. If your phone is 5G and connects to the same cells as the gateway and works when the gateway does not that might be a clue. I live in a rural location and both my iPhone and gateway connect to the same cellular sources often. Using the metrics reporting with my phone I can identify the cell ID information. Cellular just takes more effort than having a hard line to the home. Here I have no hard line option. So, I have learned to work with the cellular signaling.

I had one of the little hotspots here when we first moved here but dumped that for the home internet gateway. The terms are better and the cost is better, unless they have improved the terms for the inseego hotspot. It is really easy to burn through 10 gigs of data in no time. If you don't need the mobility the home gateway is a much more cost effective solution. I believe you would see a significant improvement in signal reception as the antennas are larger. Having worked with the Inseego FW2000E here and the Nokia gateway I know my internet is much better and lower cost with the home gateway vs the mobile hotspot.
