poor wifi performance of Orbi RBK20 (max 12MB/s)
Hi all, I intensively tested the RBK20 orbi and the real performances are lower than expected. The system is set as AP, the master and the satellite are connected via ethernet, the tests were perf...

to understand how i am far from best case
Just a guess here. Given RBK20 fronthaul @866Mbps, which is half of RBK53 backhual @1733Mbps, if you can get close to 20MB/s, that would be reasonable. Based on a similar test I did on RBK53 via its backhaul @1733Mbps, the peak ~40MB/s. If your wired client could get 30-50MB/s, that's also within the ball park of my test because my wired client could hit ~90MB/s. Check out this post for more details.
You can also verify if you hit Orbi peak performance by replacing Orbi with an exisitng WiFi router if you have a spare one lying around or turn on WiFi on your exisitng router if it's a combo.
What wifi band are you connecting through? If you're transfering over 2.4ghz 12 MB/s is roughly 96 mb/s. Which is pretty respectable for 2.4ghz. 5ghz you should be able to go quite a bit faster. the orbi does the band steering so you need to make sure your wireless devices are on the 5ghz for maximum throughput.
all devices work at 5Ghz, so it is strange slow performance
i tryed 36 and 44 channel
for 2.4Ghz i tested only an odroid xu4 to nas (scp protocol), but odroid wifi performance are not comparable with a pc so i have no enought number to create a report for this bands
odroid xu4's optional wifi setup is a 1x1 a/b/g/n antenna. Not ac and only single antenna. so you're right in it not being a good testing platform for wireless.
Wifi is a hard one for testing with orbi due to band steering and device selection.
What internet speeds do you pay for? What speeds do you get hardwired speedtesting the internet connection?
Have you tried speedtesting over a phone?
If so what model, what website are you testing off, and try multiple tests/disconnect/reconnect.
What wifi chip/setup are you using for testing your 5ghz with your elitebook? thats the only laptop that you've listed with wireless card. driver version on it? That's the only wifi device I seen listed for pc and I just want to make sure its not an issue with that card.
i tested lan performance because i need to fast connection between system like nas
my internet connection is VDSL, real performance is 70mb/s, and speedtest from my iphone 8 is perfect, of course
PC1 - hp elitebook G5 with realtec 8822BE
othen PC with Linux Ubuntu is probook 750 g2 realtec 8723BE but it is N only, no AC
i own an imac but it is old (2.4Ghz N), at the end of october i receive a new imac (2019), i will test it
could it be a configuration problem? any settings that reduce the maximum bandwidth per device?
I use the system as AP and not as a router, I turned off daisy chain and I enabled mu-mimo and beamforming, I tried both with and without fast roaming
