Max connection speed to RB951-2n

This might be a stupid question but it’s got me stumped.

We’ve got a 951 setup (screenshot attached) and found that our desktops connect at 150mbps.

We’ve got another AP, an engenius EAP300, with the settings as closely replicated as we can and the desktops connect at 300Mbps.

From what we understand the client should be able to connect to the 951 at 300Mbps.

Would someone be able to explain it for me?

It looks like mikrotik wants to keep a secret that RB951-2n is single chain or you can’t read the datasheet.

There are two models, one is 1x1 the other is RB951-2HnD, 2x2.

Thanks guys - we’d checked over routerboard.com but didn’t think the details would be in the broucher link :confused:

We just a couple of the new 951G’s so we’ll have a go with them.
