WLC2504 low speed

[3dtgnt_ljm]

Hi All ,

our company has a wlc2504 with 8 1602i APs connected to a Gig switch, but client has a poor speed when they copy files. normally only 256kb/s , I tried changed one ap as fat mode, it more faster than other thin APs, 1.2Mb/s downloading on a 100M switch. I turned off 5G left 2.4G but no effect. and today morning I upgraded wlc's ios from 7.4 to 8.0 but downloading speed no changed. is it a bug for this wlc ?

100 Mbps switch????  Can you check the switchport interface between the WLC and the switch?   Can you also check the UPLINK of the same switch?  

Your description sounds more like a LAN issue than a WLAN issue.
