WiFi through put

RouterOS Wireless Networking

So I may have a very basic question but cant find an answer.

We will just use 802.11N for this and the test was done with 3 different types of access point models and 3 different computers.

So I connect up to the AP at 150 meg. With this speed I would expect in a clean environment to get 75x75 meg connection.

I am not in a clean environment and my speed test gets me 50x18 at best on any of the aps.

My question is my upload never ever gets above 20 meg no matter what AP or computer I use.
Is there a reason to this part of a standard I just cant find?

Thanks

Is the test doing upstream and downstream simultaneously?
If so, then you should expect an imbalance like this because WiFi is half-duplex, and it’s not going to just balance evenly at half up and half down.

No the upload and download tests are done independently.

Silly question here - is this a speed test to the Internet, or to an internal server?
And if it’s to the internet, you have a connection that’s better than 50x20 I’m assuming…

it is internal using btest to a mikrotik switch

Using udp or tcp?
I’ve found that TCP mode is verrrrry sensitive to even the tiniest burp and will report far below what can really be done unless you have a completely perfect connection.
UDP is a good gauge for determining maximum throughput - but will tend to find something a bit higher than real-world TCP will do.

Through put has been tested on both TCP and UDP. Now I finally found a laptop that would get me the speed I would expect. I have no idea why it works and the others don’t other then just something with the WiFI card setting that is not obvious to me.

Thanks

My Apple iStuff won’t go as fast as my HP laptop will - they only have 1 chain and the laptop gets 2 chains, so it can go faster. Wireless is only about 1 step removed from voodoo in my opinion.

“If I sit on the left side of the couch, I get 100Mbps, but on the right side of the couch, I get disconnected from the AP.”

Or one I really had: “When the phone rings, I get disconnected from the Internet”
This has been the problem description in a trouble ticket before.
Really.
