I am having issues with my Orbi system in regards to maintaining a consistent speed. Within 24-48 hours of rebooting my RBR and RBS's my download speeds will drop and remain at 70-80Mbps. I am on a 400/40 plan with my ISP (Suddenlink) and my upload speeds are uneffected. If I reboot my Orbi devices I am able to acheive ~400Mbps speeds initially.

 

Here is a simplified (wired) Network Diagram:

Internet -> NETGEAR CM700 -> EdgeRouter X -> NETGEAR GS105NA 5P Switch -> RBR50 (AP Mode).

 

(2) Additional RBS50's, wireless backhaul. Each around ~25-30ft from the RBR50.

 

Single story home, ~3100 sqft. Interior construction is wood/drywall.

 

I have tested wired connections at all points (Modem, Router, Switch) and performance is as expected.

 

Looking at the Orbi App I see a number of 5Ghz connections with exceptionally low link rates <100Mbps. However, initiating a speed test on my laptop (Shows 866Mbps and is located within 3 ft of RBR) I am experiencing the same 75-80Mbps download speeds.

 

~40 Wifi connected devices including: TV's, Fire Box/Stick, Laptops, Phones, Echo's, Thermostats, Ring Cameras/Doorbell. 10 of those are Sonos wireless speakers.

 

Router Firmware Version - V2.3.5.30

 

Wireless Settings (GENERAL)

Region	North America
2.4G Channel	Auto ( 7(P) + 11(S) )
2.4G Mode	Up to 400 Mbps
5G Channel	36+40+44(P)+48
5G Mode	Up to 866.7 Mbps

 

I'm at a complete loss here, performance is as expected after reboot. Degrads to a CONSISTENT 75-80Mbps after 24-48 hours and does not recover until a reboot.
