Ever since 2.1.2.18 my RBR50/RBS50 AP Mode setup will not go above 10-20Mbps download on any device I test from (tablets, phones, laptops). I have verified via wired connection my internet is functioning properly (120/10). The devices can be connected on 2.4 or 5Ghz, it doesnt matter just slow speeds all around

6D) Just to add, I am a network engineer... troubleshooting network issues is something I have been doing my entire career. I am human and may have missed something but this is a simple network setup and sectionalizing the issue has shown me it is orbi. 

 

>>  6D)  I would guess that you have run tracert command based upon you being a network engineer.  What were the results up to where you connect to your IP host provider (next hop just outside your cable modem)?  Anything stick out?

 

Networking is like a bowl of cherries. 

You don't want to eat the stems.

Couple things:

1) traceroute (mtr actually as it looks nicer :) ) have looked clean, nothing to indicate a problem

2) given that speedtests from the Orbi itself and via wired are fine than I would not expect an issue on my router/fw with my ISP.

Again the only issue I see is with wifi devices that cannot seem to break this 20Mbps barrier no matter if its on 5Ghz or 2.4ghz and no matter the device.

Here is an iperf test result between a wired linux host in my network and a laptop on wifi (Macbook pro on 5Ghz), bit better than speedtest (slightly over 20) but still terrible:

To the same iperf server again but this time wired, to show it can handle up to 1Gbps:
