Orbi RBKE 963B - slow wired connection - running out of ideas.
Fiber connection (1gbit up/down) -> Cat6 -> 963 router -> Cat6 & Cat7 cables to 2 PC's using the 2.5gbit LAN + LAN 2 Satellites working just fine, solid 6-700mbit up/down with no issues what so ...
Is it both the 2.5G and 1G Ethernet ports that do this?
Have you tried using two 1G ports and leaving the 2.5G port unused?
As long as the router is running the current firmware, v6.3.7.5, looks like a call to Netgear support is in order.
(If it is not on the latest firmware, they'll just tell you to update firmware, which will cost you time.)
As long as you are enjoying this novel experience, there is one more goofy experiment:
Load up iPerf3 on both PCs. https://iperf.fr/iperf-download.php
Open iPerf3 on one PC as a server and the other PC as a client and run a test.
When I do this on my ancient RBR50, iPerf3 consistently reports about 940MB/s, which is the maximum possible on 1G Ethernet:

iperf Done.If two PCs connected to the 960 Ethernet ports do not perform in a similar manner, I would be very disappointed.
Hi,
Very interesting test indeed.
Check this out. This is consistent with the speeds I'm getting on fast.com + Speedtest (app and web, same results)
Using this argument:
iperf/iperf3 -c remotehost -i 1 -t 20 -r Run a test from remotehost to localhost Then I ran iPerf3 with a different argument
iperf/iperf3 -c remotehost -i 1 -t 20 -w 32M -P 4 Run a test with 4 parallel streams, and with a 32M TCP buffer ... and got better results:
Not sure what conclusions to draw, or where to go from here?
Oh, my. parameters! My test was plain vanilla. Since that maxed out a 1G connection, I stopped there.
The concept was to isolate the problem to:
- The Orbi router processing, or
- The Orbi Ethernet module.
Thinking that a connection between two wired devices would not even enter the router software, but be handled entirely by the Ethernet switch module. This is one obvious difference between my old RBR50 and the RBRE960 product.
- Mine has a traditional four port Ethernet module that has probably been around for a decade and is built into countless products from almost every manufacturer.
- The RBRE960 has that 10G, 2.5G, three 1G ports setup. I have no idea how that works. I would be happier if iPerf3 between two of the 1G ports behaved like my router.
It's probably not helpful to mention that with my Spectrum cable plan, Speed Test regularly reports 330MB to a wired PC. I get more with an ordinary cable plan through an ancient router than you do with a gigabit ISP connection and the latest model.
Did you ever fix this issue? I am having the same problem on Fiber 940/940. The issue seems to resolve ONLY when I downgrade the firmware.
