I purchased 2 Poynting LPDA-92-04 High Gain LTE Antenna’s and set them up in Mimo config (45 degree and 135 degree) and when the Pepwave reboots it just screams. Tripled my download; quadrupled my upload.
Anywhere from 1 hour to a couple of days later I notice a significant drop in speed. I use Speedtest to check the speed and it connects to the nearest server. When it boots it connects me to Omaha. When I check when the speed drops, it will show closest server to be Des Moines, Wichita Kansas, even Minnesota.
I also have 2 factor authorization turned on in Facebook. When I login it will prompt me on my mobile and say “Did you just login near Omaha?”. Later it will say “Did you just login near Des Moines?”, etc.
I have turned off band 4 and only have it select to band 13. Where I live, band 4 has always been way to slow and I do not get the same speeds.
