indoor .11n ap recommendations

Hello all!

I would like to commission a new access point in our office, and swap the flaky ProCurve 530 AP that is currently in place. We have maximum 5 notebook users, maximum 5 WiFi phones and 2-3 guests with notebooks sometime. At average there are 3 notebooks and 2 phones using the network, so no big deal.

Currently everbody has 11bg cards in the notebooks, but probably we will change some notebooks to ones with 11n capable wireless cards this year. So I decided to buy an RB411AH with R52n and two rubberduck antennas.

This is an office building in the centre of the town with blocks of flats on one side, so the 2,4GHz spectrum is a bit crowded. I can see about 10 SSIDs on my notebook, and about twenty when doing a wireless scan with the routerboard. So I chose mode b/g/n and a channel which had minimal interference on it and the neighboring 2-3 channels, but the other configuration is pretty much the default except ticking both HT Rx and Tx chains. The board is running v4.4 with the standard wireless package.

If you have experience in configuring indoor 11n, and would share your recommendations with me, thank you in advance.
