Current recommendations for a 4g lte router that will run openwrt

Hardware Questions and Recommendations
1

I currently have a GL.iNet GL-SFT1200 on my boat. I have it setup to use the marina wifi on my own wifi name and if the marina wifi isnt available it fails over to the plugged in 4g usb stick. Works ok but the antennae arent removable and i think i could catch a better signal.

Im looking to try another solution. Preferably an lte 4g router all in one unit. The tp link mr6400 looks promising but is there anything newer/better i could look at that will allow me to have wan / lte failover? (I assume if the unit runs openwrt then failover will be possible)

Thanks in advance

I'd get a USB LTE modem, you can put in a window, while the actual router sits someplace else.

Hi.

A good try would be WE826-T2

https://openwrt.org/toh/zbtlink/we-826

ZBT WE826 T 32M, with black metal case model , LTE and wifi detachable antennas.
Used 2 units for remote location where local wifi was unstable. Openwrt friendly, and working great.
Just remember to chose the correct LTE modem for your area. Vendors are selling them with no LTE modem, or with the desired modem for your country.
