@Mchccjg12, do you notice the EM7565 is markedly better than the 7455? Is there any modem out there that doesn't have this problem with Sprint that we could use in a similar way?
The EM7565 is definitely leagues better than the 7455. It disconnects far less, and is much more stable, though the lack of Band 25 is a decent downside. Honestly, it truly depends on the area. Sprint is better in some areas than others. In my area, even the 7565 disconnects because the local towers are having trouble. But then again, even the official hotspot I have has issues too, so it ain't just the 7565.

I was having lots of disconnects daily with EM7455 in one of the USB2 enclosures. I upgraded the firmware to the latest 2.32 and moved to the USB3 enclosure from ltefix. (My AR150 is USB2, but the enclosure still works). My disconnects have dropped dramatically.

I also changed the connection monitoring script to do a dhcp release / renew instead of reseting or power toggling the modem. This is much faster recovery and restores the connection.

very interesting. With this new setup, how frequently is it disconnecting?

Update on this...per your results I ended up picking up a usb3 enclosure from ltefix for my em7455 and sprint is a lot more stable with it.

Can you post how you tweaked your connection monitoring script to dhcp release/renew upon disconnect?
