What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or may not be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

Has a factory reset and setup from scratch been performed since last FW update?

I've been struggling with this for over 6 months, and am about ready to abandon Orbi & buy Eero, but before I do, I'll give the Orbi one last chance here.

 

I have an RBR50 with 1 satellite & 1G service from ISP.

 

RBR50 is running on latest firmware (V2.7.2.102).

 

After I reboot the router, and generally for about 10 days thereafter, all is good: all devices in the house get full bandwidths via wifi, as expected.  But then, for no apprent reason, usuallly between 1 & 2 weeks after the last reboot, and this change always happens overnight, I find that our MacBook Pros are throttled to <40Mbps, while our iOS and other devices remain unaffected.

 

I've seen other past posts about the same behavior, where updating to newer firmware helped: I started seeing this under an earlier version of the firmware, and the update did indeed fix it, but only for a while, and now, it's systematic that I'm ending up having to reboot the router at least every 2 weeks.  A real pain since our whole house depends on bandwidth now with WFM under COVID, and each reboot inevitably disrupts various video meetings.   This simply should not be happening with a supposedly top line product.

Is there a CLEAR fix, or should I just ditch Orbi & buy Eero?
