I've got an X750v2, using a Visible SIM card. The SIM works great when in a 4G phone, hotspot works fine 24/7. I have cloned the IMEI into my x750. It works, but I get fairly frequent "LCP terminated by peer" in my logs, and the cellular connection drops and gets reconnected after a minute or so. The cellular settings that I've managed to get working (other than these disconnects) are:
cellular protocol: 3g
port: /dev/ttyUSB3
APN: VZWINTERNET
TTL: 88
TTL IPv6: 88
Authentication: PAP/CHAP (no username or password entered, also works without this auth method)
I'm using the latest firmware (as of 5/6/2025) - v4.0 - 0325release1.
Any suggestions regarding how to avoid the "LCP terminated by peer" disconnects? Best I can tell that's the ISP disconnecting from their end. Is it something that might be resolved by getting an X3000 instead of the older X750V2?
Thanks for any help.
