We have a 50/50 symmetrical fiber connection in our office, and a ZoneDirector 1106 with two wireless access points, one on each side of the building. We have most of our employees on one side (working on wifi with MacBook Pros), and our conference rooms on the other. Until recently we had a 7982 AP on the side where everyone sits, and a 7636 AP over with the conference rooms. Usual connection speeds over the wifi are between 20-40 Mbps.
This past weekend we replaced the 7636 with another 7982, replicating all of the same configuration settings. Now internet speeds have dropped for our users to between 10-20 Mbps average. A laptop plugged directly into our router gets close to 40 Mbps so the problem doesn't appear to be our internet connection.
Why might this be happening? What steps can we take to troubleshoot/correct this issue?
