Wired ports on Orbi show declining speed on every test typically ending around 500mb
Have a similar issue with my Orbi RBR850 and 2gb frontier fiber. Speed tests to the RBR850 max out at 2.3gb every time. Wired ports on Orbi show declining speed on every test typically ending aroun...
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
How many RBS are deployed?
What is the size of your home? Sq Ft?
Does this happen with the RBS turned OFF?
Does this happen with both wireless and wired devices?
What channel configurations are currently set on the router?
Is SIP ALG enabled or disabled on the RBR?
Speed test results same across two wired PCs?
Thank you for asking and offering to assist. See my answers below:
What Firmware version is currently loaded? - Firmware is 7.2.6.21_5.0.20
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? - The ONT is an XGS-PON ONT Model: FX523 from Intertek
How many RBS are deployed? 1 RBS deployed. Wireless isn't really my issue however.
What is the size of your home? Sq Ft? - 4500 sq ft. As stated however, am focused on the wired speed issue
Does this happen with the RBS turned OFF? - Yes I did try this with the RBS turned off. Same results
Does this happen with both wireless and wired devices? - The issue is with wired connections, specifically with download speeds. Wireless is more consistent but still shows a drop on download speeds.
The below is a speed test example on wired. note that the upload speed is what I expect for a 1gb connection and has never been an issue - only download speeds. Note the drop in the blue line indicating that a download test starts at a higher speed and then decreases to ~ 500mb.
What channel configurations are currently set on the router? - As mentioned wifi isn't really the issue I am trying to solve however: 2.4Ghz = Auto and 5Ghz = 40
Is SIP ALG enabled or disabled on the RBR? - NAT Filtering is disabled
Speed test results same across two wired PCs? - Yes the issue is the same for two different MacBooks from two different wired drops in the home. Have tested these drops to 1gb with iperf3 consistently so believe I am getting consistent wired speeds and do not have a cabling issue.
Also as I mentioned in the original post, direct connection to the ONT produces consistent speed results (topped out at 1gb). it is only when I use the RBR850 and its LAN ports that I am experiencing the issue with degraded download speeds.
Hope this is clear enough. Appreciate your inputs following.

Did you happen to power OFF the ONT for 30 seconds while performing a factory reset on the RBR and setting it up from scratch, then go in and speed test with the wired PC?
Sounlds like the RBR is not getting or handling the speeds while connected at the ONT. Wondering if there maybe some issue in FW with this particular ONT.
Any chance you have a friend, nieghbor or family member around to take the RBR to and see if problem follows?
Is SIP ALG enabled or disabled on the RBR? This is not NAT Filtering.
Can you are using a CAT6A STP cable between the RBR and ONT?
Did you happen to power OFF the ONT for 30 seconds while performing a factory reset on the RBR and setting it up from scratch, then go in and speed test with the wired PC? - Yes have done this several times, unplugged both RBR & RBS and ONT. Brought up RBR850 alone and factory reset followed by powering on the ONT. Then proceeded to set up the RBR850 (again alone) from scratch.
Sounds like the RBR is not getting or handling the speeds while connected at the ONT. Wondering if there maybe some issue in FW with this particular ONT. - I wonder the same. Have talked with Frontier support multiple times to have them 'check' the ONT. they have reported no errors found on the ONT each time. There is no user access to the ONT that I can find to check myself.
Bear in mind two factors. 1. Whenever I speed test from my laptop on wired I ALWAYS get 930-940mb uploads via the RBR850. It is download only that is affected. And 2. Speed test from the RBR850 reports 2.3Gb Up/Down consistently every time.
Any chance you have a friend, nieghbor or family member around to take the RBR to and see if problem follows? - Good Q. Unfortunately no as I don't have anyone else around at 2gb
Is SIP ALG enabled or disabled on the RBR? This is not NAT Filtering. - it is disabled (see screenshot)
Can you are using a CAT6A STP cable between the RBR and ONT? - yes. This is one of the first things I checked into and then replaced.
Have also done multiple log captures via the debug.htm screen. There are many log files in here but nothing I've seen so far that leads me to better understand what is going on with the WAN connection.
Is the ISP configuration on the ONT DHCP or does the ISP support PPPoE on the RBR?
If you have logs, I recommend opening up a support ticket and attach the logs. Make note of everything in this thread, include this thread as well. https://my.netgear.com/support/contact.aspx

Then clicking on "Get answers about NETGEAR products before I buy" then clicking on "Networking for Home" then "Chat with us".Only other item to try, if you have a different router, test that router with the ONT.
Something on the RBR or in FW in not working well with this ONT and ISP service. NG will need to take a look.
