Hello, We recently purchased the RBK853 AX6000 system to provide coverage for my home which is roughly 6,500sqft. We've updated the current firmware and done a factory reset from the start. Now I'm trying to wrap my head around why different speeds are being advertised then what I'm actually getting. Common FAQ: ISP : Cox GigablastModem: Netgear Nighthawk CM1100 DOS 3.1 (Cox approved modem)Connected Cable to main router: Cat5EPurchased From: AmazonSpeed from Modem: Directly plugged in reached 1Gigabit to laptopRouter Settings: IPv6 Enabled, DNS Set to Google default for Ipv4/Ipv6 Done mutliple restarts, Connected device from screen shot is from an AC Client laptop.

What Firmware version is currently loaded?Is LAG disabled on the CM modem? What are the wired speeds with the wired PC connected to the back of the RBR using Ooklas installable speed test app? AC client wifi will max out at around 400-500Mpbs depending upon mfr design and support. Will never see anything near 900Mpbs. Wired connection with a PC should see near 900Mpbs or over... Heres what I get with my Orbi AX sysetm on a Mac Book Pro 2018 wirelessly connected to the RBR: Be sure to power OFF The ISP modem for 1 minute then back on when rebooting the RBR. Is Armor enabled on the RBR?

NG doesn't commonly comment in forum posts. I recommend you open a support ticket with NG support and make contact with them directly and ask for additional help and information.

Thank you for the reply, The current firmware on all units are V3.2.16.6.LAG is disabled. Here are my wired speeds from my AC client laptop.

Those are good wired speeds. Wireless will be different on AC class devices.

Thank you for the insight, however I'm still trying to resolve why my wireless speeds are no where near what I should be getting. Also Armor is disabled.
