I have been using my RBR50 system for a few years. I just switched back to Spectrum (on 400mbps plan), and am not getting more than 9mbps down on either wired or wireless when connected to the Orbi. When I direct connect my PC to the modem (en2251) I get 470mbps. So the modem is OK.Over a year ago, on Spectrum with ARRIS SURFboard SB6141 with 50mbps - no issues with using the RBR50.Past year, on AT&T 1GIG service, of course I never received 1G but no issues. I had to change the router to AP mode to work with ATT routerToday, back on Spectrum with their en2251 modem. Initially I just changed the Orbi from AP mode back to router to connect to the new service. When the speeds were slow, I did a full factory reset of the Orbi -same results. The firmware on the Orbi is v2.7.2.104 and the app indicates that is up to date.I have fully restarted the mode and Orbi multiple times with no changes.Of course Spectrum indicates this is my routers issue (have not actually called them yet, just went through their troubleshooter tool). I did try and search for any answers myself first, but not finding anything - seems most slow issues I find are with wireless only. Anyone have ideas on next steps for troubleshooting?

Just some more information * Modem and router are right next to each other* I have tried a different brand new network cable - both cat 5e* Armor was on by default when I reset the router, but I have turned that off and verified traffic meter is not on* Speed tests done using speedtest.net, the one in the orbi app, and on the Spectrum site - all show the same on wirelss using phone and PC direct connected to the Orbi router.* Network performance is impacted, I am not just going just by speed tests. Streaming netflix/amazon both on wifi and directed connected takes time to load and degraded quality.

What happens if you wire connect a PC or laptop dirctly to the ISP modem with out the RBR online? Also test with the wired PC connected to the RBR. 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: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). One User Experience/Configuration:https://community.netgear.com/t5/Orbi/Most-Stable-Orbi-Configuration/m-p/1941087/highlight/true#M97026 Any Wifi Neighbors near by? If so, how many?

Thanks, I will take a look at all your other items, but quick reponse on the first two questions: When I direct connect my PC to the modem (en2251) I get 470mbpsWhen I direct connect my PC to the Orbi I get same 9mbps speed as wireless We do have close neighbors (but not close like apartments), I can see quite a few other networks out there - but the problem is not just wireless so I don't think that is the issue.

When you direct connected to the RBR, you are ethernet connected right? Using good quality LAN cable? CAT6 is recommended. How are you speed testing? Speed test site on web browser or Ooklas installable speed test app? What is the connection rate reporting of your ethernet adapter connected to the RBR? Should be 1000Mpb. After the factory reset on the RBR, your not enabling Armor, Circle, Access Controls or Traffic meter right? Powered OFF the ISP Modem for 30 seconds as well during the factory reset of the RBR too?

When you direct connected to the RBR, you are ethernet connected right?That is correct Using good quality LAN cable? CAT6 is recommended.Cat 6 between PC and RBR, cat 5E between router and RBR. I don't have another CAT6 to try between the two, but I am using same as I always have with no issues. But have tried a fresh never used CAT 5e during troubleshooting. How are you speed testing? Speed test site on web browser or Ooklas installable speed test app? I have used on web browser Ooklas site, Spectrum site. On mobile, Orbi app and Ooklas app What is the connection rate reporting of your ethernet adapter connected to the RBR? Should be 1000Mpb.I am not sure about this, I will look into how to find out After the factory reset on the RBR, your not enabling Armor, Circle, Access Controls or Traffic meter right?Armor was enable by default but its off now. Verified Traffic meter is off, no access controls. Not sure about circle, will look into it. Powered OFF the ISP Modem for 30 seconds as well during the factory reset of the RBR too? Yes, each time I turned off the ISP modem I would wait at least one minute. I did this before trying anything else, during the factor reset, s well as when I switched to/from direct to modem from my PC.
