Update that to show that anything based on AR9271 will not work on 6.2 or 6.3 mips… I’m on my 4th adapter using this chipset and none have worked with 6.2 or 6.3…
Have you sent supout to support@mikrotik.com? They may be able to add support for those devices.
Not worth the time. This morning I’m preparing to sell my remaining MikroTik units to whatever sucker comes long for them and be done with it.
what equipment are we talking about and what are the prices? 
Just to let you know, the list is updated by users, so you could update it too, if you tested the mentioned devices
If only I knew how to register for the wiki. I tried to find out but whithout success. Others in this forum tried, too, requested support and got told the feature is disabled and only MT can edit anymore.
This is false. Mikrotik is no longer allowing users to register on the wiki to be able to make changes.
It is not so. Registrations are approved per individual request.
That’s good news, but this also seems to be a well kept secret. Would you mind sharing how to contact MT and what requirements we have to meet to get access? And shouldn’t this information be shared on the wiki, too?
I’d gladly had added some supported SFPs / some configuration examples if only I could.
Isn’t it easier just to look into the ROS source and write out a full list of supported chipsets now and then? You can do it in no time, but the ROS user must pay first to get a device X and then test to find out that it is not supported. Clearly the second method is much worse than the first one.
Unfortunately it’s not so easy. You could look at what devices the linux kernel 3.3.5 supports, most of the same will be supported in RouterOS. In some cases, it doesn’t support some models, somebody must test it. It’s usually easier to just use a RouterBOARD, or to ask somebody what hardware they use. Even if kernel supports this card, sometimes special programming is needed for RouterOS to support it.
As for the Wiki, just email support
It is better than nothing, maybe we can dig up that information from there. But still, you are in much better position to do that and more.
So unless a user risks trying it out, it is not supported (since the Wiki is so far out of date its laughable).
Saying “look at what devices the linux kernel 3.3.5 supports” then shortly after saying “Even if kernel supports this card, sometimes special programming is needed for RouterOS to support it”. Means to me that even you don’t even know what other devices you really can support or not, and probably have no clue how to provide support for anything you’ve never worked with directly (which would be easy for you guys to produce a list so your users didn’t waste time and money trying things that the wiki SAYS are supported but you don’t).
That is definitely top-notch support for your customers.
