Wireless throughput

mmonty12 — Wed, 17 Mar 2021 16:40:27 GMT

I have a few different SSID’s running on eithe 250’s or 410’s WAP.

One ssid has upload and download speeds of 125 mb whils another on the same wap and using the same computer has 20mb up and down.

Any thoughts?

Hi,

What is your testing methodology? Is the computer the only connected device to this or that AP, radio and SSID?

Every device that is talking on the same BSS, and further on the same channel, decreases single station’s achieved throughput (contention, CCI). I think it’s more channel than SSID related so could you please confirm you connect to both SSIDs on the same band? I’d also double check User Profiles if there is any rate limit set.

Hope that helps,

Tomasz

Tomasz,

I am logged in as a domain admin so no restrictions. I am uainf the same computer and the same speedtest site via a browser. I am on the network hours before any other users and it does not matter where I do the test from the results are the same. I have appox 40 WAP’s. I run the test from different buildings and locations within the building and getting the same results.

It just isn;t making sense to me as to why…..nothing has changed in my environment as I would have had to be the one to change it.

Thank you for your reply

Hello,

are you connected to the same frequency (2.4 vs. 5 Ghz) with the same 802.11 standard?

Stephan,

Yes which is why I am scratching my head.

Hmm,

what do you see in “Client 360”->”Session detail” during you test?

Do you have an screenshot?

Hi,

Another food for thoughts, how are the APs placed? Had once a situation where we could get 100 Mbps for testing purposes (with iperf of course, not speedtest) but in one place it was just 100 Mbps right under the AP and < 1 Mbps single step away.

What is their TxP, is it the same everywhere?

Hope that helps,

Tomasz
