Any advice on manually setting up the 5 Ghz channels? Also I would like to use the DFS channels so that I can get a wider range to choose from. But I have noticed that the wattage correspond to the channel I choose in this band .So would it be advisable to use two 165s close enough or should I design the channel selection keeping the distance into consideration as well.

Using tools like Ekahau Site Survey and Airmagnet survey will help design and verify these installs. We went from 20 to 40 a few years back, but move back to 20 by default early last year. We have a few 40Mhz locations where we can, we could probably do a lot more but unless we have time to design and test we leave things at 20.

Our campus presently uses 20MHz channel width in all buildings. We are testing and considering 40MHz width because of the bandwidth benefits for clients. What do you use on your campus? Have you found that setting a 40MHz channel width on your 5GHz radios has caused too much interference?
