RB912UAG-2HPnD + Huawei EM820U

Hi
Looks like I might have bought the wrong mini-PCIe 3G card. I bought a Huawei EM820U but it seems that this is not supported however the EM820W is. Can someone please confirm if it is possible to get the EM820U working or not and if so how so.
Thanks,
Tim

Upgrade to v6.4, and make a supout.rif file with the card inside. Then send to
support@mikrotik.com
Maybe we can add support

I also ordered a Sierra Wireless MC7710 3G/4G mini-PCIe card to try as well. Unfortunately this also doesn't work

Hi
Still no luck with either. I've also updated the MC7710 to the latest fw:- MC7710 FW 3.5.24.0 (QMI)
See attached supout.rif file.
I'd really like to get both cards working as the Huawei one is a lot cheaper but the Sierra Wireless one offers DC-HSPA and 4G.
Kind Regards,
Tim

Ok so I have the MC7710 connecting now, however can not actually browse the internet.
However if I ping bbc.co.uk it will return the IP address (212.58.253.67) but the ping will time out.
The IP I have been allocated is also the same as the default gateway ... this can't be right, can it?

Hi
I seem to have it working now. Not quite sure what I done, but it works...
Now to work on a 'nice' standard config for this set-up.

For any one interested I did manage to get the Huawei EM820U working.
It was really simple when I realised that this card required a ppp connection and not a DHCP client like the MC7710!
Set ppp-out1 to use USB2, data channel 0, info channel 2 and APN three.co.uk (in my case, for three in the UK)
You will also need to add a NAT rule. chain: srcnat, out interface: ppp-out1 action: masquerade
Then you're all good to go

Because you need to use the DirectIP (DIP) firmware.

I have tried (DIP)
SWI9200M_3.5-Release2-SWI9200X_03.05.14.00
SWI9200M_3.5-Release7-SWI9200X_03.05.23.02
SWI9200M_3.5-Release8-SWI9200X_03.05.24.00
I have os 5.26
Should it not show up under "interfaces" or "LTE" by itself?
It show up as unknown...
What do I miss?

Use SWI9200M_3.5-Release8-SWI9200X_03.05.24.00, this is what I used an I know this works.
Although RouterOS 5.25+ should work I'd recommend using the latest, 6.12.
If you can not get it to work in the mikrotik then test that it works in a PC/Laptop with a WWAN mini-pcie slot, which I assume you have as you have upgraded the modem's firmware. You can use AirCard Watcher to use the modem in a PC.
