Question : Problem: Need to map signal strength for 20 Access Point network

About 2 years ago I installed a twenty point WAP network for a hotel.  Last week, they have been getting complaints about dead spots, weak signals.  These are autosensing WAPS, so singal overlap shoudl not be at issue.  Anyone know a good software to map the hotel's 802.11 signal strength in various areas.  I am prefering to find somethgin that is mainstrteam (i.e. supported)  My assumption is that it is interference, I need to determin the source.  Prefer to have an application that can report to a map.
