If you do a spectrum scan it shows signals of other APs in dbm. If you use have one as a station, it shows dbm on the main page. On an AP, if you show stations (list of associated stations), it shows a positive integer "RSSI" which I would presume is the same as SNR as it's definitely not dbm. (I am told to add -97 to it to get dbm) So you get dbm on the stations, on surveys, but not on the AP for the radios associated.
