OK

I assume that’s not the latest firmware - is it? How do I update the firmware when an HL7800 is involved? All the guides I keep finding are for WP series - not HL series.

Thx!

Looks like I did already update the firmware. 4.6.9.4 appears to be the latest. Found the instructions for the HL7800 here: https://source.sierrawireless.com/resources/airprime/software/hl7800-firmware/hl78xx-firmware-4,-d-,6,-d-,9,-d-,4/#sthash.4srFDCt3.YG0tx7AO.dpbs
