WAP AC wirelles perfo

Thu Aug 24, 2017 4:32 am

Hello,
Who already tried Wap AC device? Did you get good speed over Ac wireless?

Just to give you an exemple :

My ISP : 100/100 (tested from a connected Computer to the routeur (750upr2) 91.5mbps/89.9mbps)
The Wap AC is connected to the routeur directly with the POE injector that come with.
My phone :Pixel XL (android/Goggle phone)
2.4 band : +- 37mbps in and out
5.8 band : +-52mbps in and out too

I was about 10 ft from the WAP AC.

Do i need to setup the gear before using or it supposed to be ready to achive speed of at least 100mbps ? AC gear can easily handle 100mbps over wireless RIGHT?


Thx a lot.

### I tried 20/40/80 band and nothing happen.

Ran an iperf to a server on a different VLAN and here is what I get on my WAP AC running 6.41rc7 (need to upgrade it today ... doh):

TX Rate 135Mbps 40MHz
RX Rate 180Mbps 40MHz

My client is connected at -67. I use a TP-Link AC PCIe card in a desktop machine.

My TCP performance is ~32Mbps
My UDP performance is ~92Mbps

Wireless performance is highly subjective, during my test I had several other devices eating up air time and I didn't do anything to try to optimize my test results. In particular, wireless is half-duplex. When looking at TCP performance you are going to see a larger drop in performance for that reason. The client is waiting for ACKs but can't send them unless the sender stops talking (sending) even in a single direction test. Pair that with the heavier wait of TCP, connection tracking, bigger packets, etc... and you'll see slower performance than UDP. Testing UDP will get you closer to that "ideal" rate but let's be honest most of the traffic we care about today is ultimately TCP (possibly wrapped in a UDP based VPN).
