In my 3-building campus, we have deployed Airespace 4136 WLC, and Cisco AS1000 and AS1200 APs throughout the campus. 8 APs per floor, serving an area of up to 40 users per AP. However, most users connect using Ethernet cable. My problem is that the APs on one floor (which happens to be the Executive floor) the signal strength is usually Low to Very Low, prompting some complaints, like unable to connect or to even get a signal. But once you go to other floors, signal strength is Excellent. Can you tell me what are the usual causes for the spotty service? what instruments can I use to help me out.
The building next to us is one of Yahoo! offices, but I don't believe that there is any kind of interfearance, since it is only happening on one floor.
Thanks in advanced for your opinions.
You probably need to look at RRM in hte controller chanches are the controller has set those AP's to a very low power level for some reason.
