Has anyone used L850-gl 4G Card with mikrotik?

RouterOS General
1

Looking to buy this card since it does support all the 4G bands where I live (2,4,7,28,66).

I have only seen one thread that looks like it does work? (http://forum.mikrotik.com/t/fibocom-l850-gl/145066/3)
it states that Mikrotik sees the card as ppp. What does this mean?
Can I access the card using AT commands (to force channel lock)

Thanks

Probably you are interested in USA… then you should think about USA problems like
IMEI of lte card will be recognise as hotspot/mifi device and give you other plans then phone (worse).
You must first get a AT Command documentation of module
You must know that m.2 modules need adapter from mPCIe what MikroTik use.

Without that problems you can take Quctel EP06-A, and HotTo is in my signature KB for EP06-E, commands are the same.
Still you should consider using RouterOS v7.1 release candidate, this is not stable but if you want only get internet and wait 2-6mth then ROS should be stable to this point, we all hope that.
For now this info I provide you because I can say in one sentence… found proper Quectel lte card, this is better direction then Fibicomm.

Commands for OpenWRT are:
L850 Will work by using MBIM mode :

AT+GTUSBMODE?
AT+GTUSBMODE=7
AT+CFUN=15

Still looking if this will work with RouterOS

I have it running on routeros 7.8:

I used the following at commands:

at@nvm:fix_cat_fcclock.fcclock_mode?
at@nvm:fix_cat_fcclock.fcclock_mode=0
at@store_nvm(fix_cat_fcclock)
AT+GTUSBMODE?
AT+GTUSBMODE=7
AT+CFUN?
AT+CFUN=15

After that, I still had problems. I had to upgrade the firmware of the modem, using the instructions here (using google translator):

Hi everyone, since I have always had problems with R11e-LTE6 modem through firmware up to v035, carrier aggregation issue, link down every 15-20 minutes, just fix one band works well, I decided to try Fibocom L850-GL, supported since RouterOS 7.7 .
At first it was not recognized




but after firmware update it is recognized (MBIM mode) but still not working well, AT commands don’t work, no internet connection…

Can someone help me? Thanks!

p.s. RBLHGGR on RouterOS 7.10

With RouterOS 7.11 in changelog they mention with “lte - added “at-chat” support for Fibocom L850-GL modem;”
but I’m tested at-command with L850-GL on hAP ax3 and hAP ac2 It’s still not working

7

What happens? e.g. an error message, or is the “at-chat” command not there, etc?
Also does the modem work otherwise?

8

It’s return message with “failure: Modem unsupported!”
for the modem status connected and the internet is ok

Try a /port print to see if there is a serial channel for usb1 and how many channels it supports. Assuming there is at least one channel, you can try:

/system/serial-terminal port=usb1 channel=0

& see if that allow access and/or if AT works.

I’ve never seen a modem that didn’t support an AT channel, but perhaps that’s possible.

10

I try to connect USB modem to PC and use putty to input the at-command It’s work fine.

11

Finally it works by FW 18500.5001.00.05.27.16 and 7.12 RouterOS

Some cell settings limitations, but by default it works fine in CA, no more link down and x3 speed, from 50 to 150Mbps!, compared to standard R11e-LTE6 modem.

12

I just came across v1.0.4 model as well, but no luck with updating firmware. Which brand/vendor card is it? How easy was to update firmware?

13

From 7.15 firmware i run into issue, duplicate lte modem device and several reboots before modem is recognized. After lte downlink, no reconnection.
I can’t downgrade to firmware 7.14. Can anyone help me?*

*Edit: to FW downgrade, first uninstall wireless package

Whats your experience with the L850-GL generally? I’m planning to put it into an SXT to replace the cat6 modem with this cat9 to get 3 CA insted of 2 after I had an amazin experience after I replaced the modem in my ATL with an RM520N-GL one.

15

Generally stable operation. No reconnection after 24h changing IP address, solved by adding script.
Only annoyance is no recognition after a system reboot or AC power loss, I have to reboot at least 2-3 times before card gets recognized.

Thanks! As it’s not for me so I ordered a EM12-G as I heard good things about that modem and turning the device on off just to pick up the modem is not an option.
