Cisco 1600 - wireless video streamning - buffer issue/keeps dropping/ distorted images

[Tsevya1]

Hello Team,

We have several APs with multiple SSID  (autonomous setup, no WLC). A video on demand  (VoD) server is connected into the same switch and operating on the same Vlan.

• Video quality from media server is crystal clear when a laptop is connected to the switch (hard wire).
• When users are attempting to view a movie broadcasted  from VoD server, we observed the following:

• Connection is intermittent, the movie keeps timing out.
• Buffer errors
• VoD images are distorted  with poor video quality

However,  wireless users can view  youtube video without any distortion or buffer issue

VoD server broadcasts unicast,   therefore ,  users can pose the movie and view it later without impacting other users.

AP  model and software version: C1600 Software (AP1G2-K9W7-M), Version 15.2(4)JA1, RELEASE SOFTWARE (fc2)

Your assistance is greatly appreciated with this matter.
