Struggling to get a Huawei 5776 (on the compatibility list) and 5377 (newer version, not on the list) without success connected to a 7800DXL without success.
Have raised a ticket, but as phone line is down at the moment (physically) I'm in a bit of a hurry and was wondering if anyone can help.
I've set 3G/LTE as primary WAN. Set the APN etc. plugged the dongle into a PC to check it connects to web via the USB link - no issues.
The 7800DXL web pages reports "3G/LTE not ready. Please check...[etc.]" and never progresses past there.
Checked the system log and it appears to mount the USB as (paraphrasing a little, had to disconnect to get on here and didn't write it down) a Storage type Device choice #1 of 1.
Thanks in advance
