RBK760 latency
I am very confused as to what to do. I upgraded from RBR50 (+ 2 sat) to RBR760 (+2 sat) because I upgraded my internet (Spectrum) from 300Mbps to 1G. I also am struggling with my son's Xbox Series ...
Thanks for the information. I see two separate issues:
- Unexpected low performance with a gigabit ISP connection
- Inability to do XBox "remote play"
A very common remote play issue is having a Double NAT, which blocks connections from the internet to the XBox. That Spectrum modem does not create a Double NAT, as evidenced by the public IP address assigned by Spectrum to the router. Nor did the XBox report a Double NAT.
Which method for guaranteeing access to the XBox did you choose? For example, did you assign a fixed IP address to the XBox and then forward these ports to it?
Addressing the performance issue, have you had a chance to perform a Speed Test on the Orbi router?
This is a version of Ookla Speed Test software that Netgear has packaged into the router firmware. Whether it is run using the router web interface or using the Orbi 'app', the test is performed on the router itself and that is what is reported.
If, for example, the latency when measured on the router is 50ms, then there is nothing the user can do to improve that.
Was the same Ethernet cable used when testing the XBox connected to the router and when connected to the downstairs satellite?
How confident are you that the floor between main and basement is only "some carpet and plywood"? My ancient WiFi5 RBR50 router and RBS50 satellite are separated by about 20 ft., 2x8 subfloor, oak flooring, at least 3 interior walls, and carpet, yet the backhaul connection between router and satellite is over 700Mbps. (The maximum theoretical connection rate if listed as 1,733Mbps which is never achieved in actual installations.) Your WiFi6 system has a maxium theoretical connection rate of 2,400Mbps.
For example, there is no air conditioning duct in the way? No layer of concrete under the plywood?
Depending on the building construction (for example is there is no finished ceiling in the basement), I would be tempted to drill a 1/2" hole and run an Ethernet cable from router to satellite.
> Which method for guaranteeing access to the XBox did you choose?
I have not assigned a fixed IP yet, nor did any port forwarding. I'd be open to learning how to do this (please see original note about not being a network/cs person.
> Addressing the performance issue, have you had a chance to perform a Speed Test on the Orbi router?
Yes, my main home computer is cat-6 into the router and when I run a speed test, I'm getting latency of about 25ms and speeds > 900 Mpbs for both up and down.
> Was the same Ethernet cable used when testing the XBox connected to the router and when connected to the downstairs satellite?
no. But I have tried two different Ethernet cables from the satellite to the Xbox and I get the same results.

I'm pretty confident that what is between the router and the Satellite is just some plywood. The satellite is in an unfinished portion of our house. And I can see the cable line that runs from the basement, to the wall-jack in our den which is where we have the modem/router.
I'm curious about the idea of running an Ethernet from the router to the satellite. I'm not aware of a wired-input to the satellite. That said, if I did this, I'd just run the Ethernet from the router to the Xbox. I guess that doesn't solve the (un)unsefulness of a satellite in the basement.
You spoke about "backhaul"; I'm not versed in this and wonder if there is something I should be doing with the router/satellite with respect to this.
Is there possibilities of other interference(s); I read about changing channels or something...I'm not sure if that is something to do...or does the Orbi system automagically do this channel optimization?
This is where my lack of experience with XBox becomes apparent.
There are generally two methods of reaching a device on the home network (LAN) when connected elsewhere to the internet:
- Directly. In this case, the device on the internet opens a connection through the internet directly to the device. The device has to know the IP address of the local network (either the actual numeric address or a URL to query a Dynamic DNS service with.) Once the connection is attempted, the home router has to forward the connection through the router to the specific device on the LAN. This method is often used to reach home security cameras, media servers, web servers, etc. It typically requires the home router to activate UPnP or Port Forwarding and these devices need to have fixed IP addresses on the LAN so the router an find them.
- Through a Cloud. This is the method typically used to reach Internet of Things (IoT) gizmos (thermostats, wall plugs, light bulbs, ovens, garage door openers, solar panels, cameras, etc.) When it powers on, each individual device opens a connection to the vendor "Cloud" and registers. "Hey. Desk Lamp 2 for owner #### is at this IP address." When the user application connects to the cloud using the owner credentials, the app sees which devices it can control (They might be all over the internet, at different locations.) That way, the router is blissfully ignorant of what is going on.
What I do not know is how XBox remote play works. That Microsoft guide implies it is a direct connection. (fixed IP, port forwarding, etc.) Yet I sense from the vague instructions that perhaps XBox remote play works through a Cloud connection. My advice: get help from XBox or their user community. (Or, maybe someone on the forum will chime in.)
Since both the XBox and the Orbi satellite seem to be portable, can you do a quick experiment and bring them both upstairs. Set them both up in the same room with the router and do the same latency and speed tests.
djhurlburt just jumping in here...who is your ISP?
I might suggest an easy test - since the 760 is a pretty powerful router, why don't you try turning the satellite off, connecting the xbox through WiFi, and see what results you get? I used to have an 860, not a ton different, and devices got a good 5GHz signal from it 2 floors away. Frequently people have too many Orbi devices vs. not enough.
Just a simple test! Don't shoot me if it's a failure, just trying to brainstorm some ideas! 🙄
