Hi Guys,

if site is having 200mbps Internet link , then what speedtest output should be for users?

some user is getting 4-5mbps and some are getting 12-20mbps

is that user should gt more than 100mbs speedtes?

Depends on how congested the WAN link.
Depends on what settings of the WLAN.
Depends on the wireless clients
Are the wireless clients testing the speed on 2.4 Ghz or 5.0 Ghz?
What Data Rates are enabled?

user is connected on 5Ghz. and Internet link is 50% utilized.

silver QoS is configured in WLAN.

can you plz tell me where to see data rates?

actually i want to know how much speedtest user should receives? any document for this?

Without knowing what WLC is used, no.

A wireless user connected to 5 Ghz can only get 4- to 5 Mbps in speedtest? I do not think so. Maybe with 2.4 Ghz but not on a 5.0 Ghz.

WLC is CIsco 5520 with image 8.5.161.0

what standard speedtest user should get to below if there is no load on BW

- for 2.4ghz user ?

- For 5ghz user?

That will depend on the wireless client's wireless NIC card. If the wireless NIC will only support 2.4 Ghz and 1 SS, then it will go as low as possible. Maybe up to 6 Mbps.

The Data Rates screenshot provided are the default value. I do not use that and tune it for higher throughput.

Can you plz share what standard data rates can be aplied? if any standard document.

Hi,

Measuring your Wireless performance by doing a public speedtest is not accepted industry-wide as there are multiple factors which impacts the RF can create an impact on the speed, most importantly if the wired network is not configured properly this could cause ripple effect. I would suggest if you want to test the WAN link independently then use a wired client for that. Then if you can move gradually towards wireless clients, when you are using wireless clients there are multiple factors impact the speed.

1. MCS rate cleint is connected

2. Channel utilization

3. Wireless client NIC and it's capabilites

4. Channel-width

etc.

So I would suggest you do an iperf test if you want to test your wireless performance. You can use the below document is a basline.
