maybe here someone can help me -
my modem show me Functionality minimum
and when I try to this :
AT!ENTERCND=“A710”
At+cfun=1
at!greset
it doesn’t help
also it doesn’t save me the at+cfun=1 , it’s return to at+cfun=0
why is it , and how do I make it work?
I have something like ~50 units and is the same in all of them
Thanks ,
You should check different ROS versions with those modem (old ones and recent ones). Each release (or even within beta series) are each pretty much different and one or two selected versions may still work for you - I have messed with similar issues for a long time already (but different GSM modem brand). Also, you may get some help from sending in a supout.rif to Mikrotik support.
I have try V5.18, 5.24, 6.2
all not working.
I have sent support mail yesterday-and still waiting for replay
Got the same problem here. Any tips ?
you need to remove a resistor in the RB
like shown in this picture:
Before removing the resistor, maybe you should try different channels?
Already tried all of them with the same result.
And what for is this resistor ?
You have K2_0_7_… firmware. It works 100% without removing the resistor. We use MC8790, MC8792V and lots of other manufacturers with RB411U and RB411UAHR.
One more stupid question…did you attach the antenna? 
Already has couple of RB411 with mc8790 and it works just fine. But this one with mc8790v got mentioned problem. And yes - firmware is K2_0_7… etc
Can anyone told me - what is this resistor for - i can remove it with ease, but to get it back - it should be a problem )

Antenna - wat is it ? o_0
As I was saying
this is the replay I got from Mikrotik support about this R
Hello,
on the newer 411U has pin22 connected to the minipcie slot. If your
sierra card doesn’t like it, you can remove the resistor which is
loaded. Here is the
picture
where you could see where to look for a resistor:
