Enterprise wireless Video quality issues

Steve Coady — Mon, 05 Jul 2021 07:33:35 GMT

Hello

My primary wireless subnet passes traffic through a Websense device. I Alway's get many "buffering delays" and video quality is substandard.

Watching video's from Youtube is frustrating on the Primary wireless.

QoS for Primary is set to Silver

Wan link is 100M and is usually running at 80%

I als have a Guest network, that uses a seperate Cable WAN link. Traffic does not currently pass thru Websense and I don't have buffering problerms.

I do get substandard video quality on this wireless network as well.

QOS for Guest is set to Bronze

WAN link in 50M/10M

I employ WISM's and Cisco 5508 controllers

AP's are mostly Cisco 1131, 1142, & 1242 models

upgrading my AP's is not a financial option at this time

What else can I look at to improve the Video quality of y wireless networks?

Simple answer is to implement

Simple answer is to implement QoS in your wireless for voice/video.

There are lots of work to do. Refer this design document as a guide.

In high level here are some task you can independantly check & configure if it is not align to recommended design guides.

1. end to end QoS configured on your wired switch network. Below blog post may give some help

2. WLC management to be on tagged vlan.(see this TechNote)

3. If all AP are local mode, then trust DSCP on switchports where AP connected.

4. Trust CoS on WLC connected switchports

5. Video traffic to be classified (AF41) and allocate bandwidth across your network.

6. WLAN QoS profile to be configured as Gold or Platinum

7. Plan your wireless to have around 10 clients per AP if they are using Video.

8. If you are using Multicast for video streaming, then you need to enable video stream feature as well.
