We´re experiencing a trouble with our Wireles LAN solution. We have a WLC 5504, a ACS 4.2 and APs 1131AG.
After deploying the solution and doing some tests we noticed when a user attempted to connect by wireless network there was too much delay since they clicked ie (internet explorer) until web authentication into WLC was shown. the delay was around 3 minutes. This issue also ocurrs despite of doing a test from my laptop that was next to one access point, then, I moved to another access point and the result was the same, a laptop problem is ruled out.
Has anybody ever had this kind of trouble? , How could I reduce this time?, is it possible?, Which part of configuration shoud I check?
