ORBI Reduces Ethernet Speed

[KSDubya]

ORBI Router is limiting ethernet network speed.

ISN speed: 300/30

Ethernet speed connected directly to SB8200 modem: 325/35

Ethernet speed through router: ~100-150/30

Wifi Speed throughout home ~270/30

It appears the router is reducing wired network speed by about half.  I've isolated this problem to the router. I've reset to router factory defaults several times.  Eliminated wiring or potential ethernet bottlenecks.  Is this a problem with all RBR50s or just mine?

Not mine, sorry.  Have you checked the data rate shown on the Orbi web interface, Advanced Tab, under Internet Port click on the box "Show Statistics"?
