Ah, yes, my bad, at the moment the 2.4GHz network is limited to 20MHz due to a bug in the drivers that we're working on solving, hence why it's only running at half speed.
I have one of the Intel cards in the office and I'll make sure we get it tested ASAP, but the whole team is really busy with the shipping right now, so it might take a little while before we get that done.
