    You could be right that there probably aren't that many 4x4 clients out there today, but people still flock to buy iPhone 11 or WiFi 6 Routers.  When comparing xFi vs Orbi WiFi specs, the Orbi fronthaul is the reason why clients will never see Gigabit WiFi speed even if it's 4x4.

We are currently tracking this issue:

This seems to be a RBR50 issue...

Hello-

 

I just subscribed to Xfinity gigabit service in Norcal.

 

I use a Netgear CM1000 modem, and I connected it to an Orbi RBK50 system.

 

My speeds are topping out at 400 mbps for all devices, including 5 ghz ones.

 

Comcast came yesterday and we verified that:  980 mbs was the speed directly from my CM1000 modem (via ethernet) and 700 mbs was the speed from my Orbi (connected via ethernet) and 400 is the speed of all devices using wifi (even a few feet away from Orbi.)

 

So I'm losing 200 mbs from the modem to the Orbi, and losing 300 more using wifi.

 

Any ideas of what could be happening?  I initially blamed xfinity, but they re-wired my house and helped troubleshoot.  The Netgear modem is getting the speed it needs.  And producing / sending the speed to the Orbi.

 

Help!
