I have an Orbi RBR50v1 with 2 RBS50v1 satellites.  Performance was fine (getting about 400  mbps download speeds), until I upgraded from firmware version 2.5.1.32 to version 2.5.2.4.  Now, I'm barely getting down load speeds of 200 mbps.  I also upgrade to xfinity 1 GB network so I'm really surprised my download speeds are now slower.  I power off all three devices and re-powered them back one by one.  They all reconnected correctly, but it the down speeds are still the same.   When I run the Orbi app's speed test, it says it is getting 800+ mbps download speeds.  Any suggestions on what I should try next?  Is it possible to downgrade the firmware?

I have seen where updating the firmware to a newer version sometimes reverts settings back to default settings.

I've updated several RBR50 and RBS50 units to 2.7.0.70 with no issues. I did find, in a few cases, where I had to reconfigure some settings to get better performance.

Check these settings:

Disable Circle, Armor, Daisy Chaining, Fast Roaming, IPv6 and uncheck 20/40Mhz Coexistence.
Enable WMM, Implicit BeamForming, Mu-MIMO
Set Short preamble mode.

I turn off all logs except port forwarding/ port triggering <- this is a preference but logging can cause overheaed

Save settings, reboot Orbi.
