Re: WIFI on RB751u-2hn
Which band is configured on your RB751?
What do you see at /interface wireless registration-table print stats?
RouterBOARD 751 wireless works great with any 802.11b/g/n compatible device

Re: WIFI on RB751u-2hn
If you look at Wireless -> Registrations what signal level and speed do you see the client connect at ?
Have you checked that you are using a clear channel ?
If using WPA2 make sure you use AES CCM (not TKIP)
There are quite a few settings which can be altered which may help
This is what I have on my RB at home:
Hope that gives you a few ideas

Re: WIFI on RB751u-2hn
One thing I have noticed is that if my laptop card is in power saving mode (eg laptop running on batteries)
then the throughput is terrible when talking to my RB751U
Seems it doesn't like the DTIM which the RB provides in the beacons.
I can fix it on linux using iwconfig eth1 power off
