Hello,
I've recently updated a few area of my buildings from to the 3802E and 3802P access points with external panel antennas for a high density of users in exhibit halls. I am running auto DCA and TCA and have the clean air enabled so essentially all power levels and channels are decided by the WLC. I also have Band Select enabled.
Prior to this upgrade, I would typically see about 20% of the clients on the 2.4 gig band. Since I have completed this upgrade to the new AP's I am seeing anything from 50 to 90% of the clients on the 2.4 gig band and thus getting horrible service. A heavy load on these AP's will typically be in the 150 clients range and I do not have the option to completely shut down the 2.4 gig range.
Do you have any suggestion for how I can improve the band select so I get back to about 80% or more of the clients on the 5 gig band? All what I can think of is adjusting the antenna gain or manually setting the TX power levels. Is this possibly a bug in the code for the 3802's?
Thank you,
Alex.
