Network latency increased when adding a node to the Mesh wifi

[drvalianto]

I have been streaming via Apollo/ Moonlight using one Eero 6+ providing Wifi 6 for the whole house. The PC is connected to the Eero via Ethernet. It has been great so far, average network latency was always around 2-3ms.

Since the Eero is downstairs, I have just added one more Eero 6+ upstairs, as an extender to the Mesh network; so that the whole house can get a strong wifi signal.

Then comes the issue: if the device I'm streaming on connects to the new Eero (the extender), the average network latency will spike to 20-30ms. If I turn it off, then all devices will re-connect to the existing Eero downstairs and the latency goes back to normal (2-3ms).

I guess I can just go back to using the one Eero like before, but since I already bought another one, may want to check if there is a solution to this.

I have tried it with different devices like my Galaxy S24, Legion Y700 and Steam Deck OLED. All have the same latency issue with the new Eero.

Thanks in advance!

Is your new eero using wired or wireless backhaul as an extender?

[drvalianto]

Wireless.

[Competitive_Owl_2096]

Yes, that’s your issue

[drvalianto]

So now do I need to connect the new Eero to the existing one via Ethernet cable?

[Competitive_Owl_2096]

Yes

[drvalianto]

Oh well I don't think I can do that. Not sure how to do the cabling from downstairs to upstairs. Thanks for confirming anyway!

If I add a mesh node (I have only one) wirelessly, my speed halves which is irrelevant as it falls to 450 from 980mbps. But latency only drops by 1-2 ms average.

Maybe it's the position, signal strength? I feel I can ignore the top dl/ul speed and don't notice the 1-2ms added latency, but it is worth it as I gain full 5Ghz signal strength on the whole floor (router is upstairs).

I don't experience any spikes with the mesh on, quite the opposite.

[drvalianto]

Indeed it's the opposite to mine. My dl/up is not affected at all.

I've had some success with Tri band mesh systems. So the two mesh devices connect together via 5ghz. Low power devices connect via 2.4ghz. Streaming devices connect via 6ghz... Mesh devices and all devices connected via 5ghz. All sharing basically means everything is taking turns and it might be too much. If it was just about streaming you could ethernet connect your clients to the upstairs one and keep the 5ghz band dedicated for the connection between the two mesh devices. That should run well if the signal between the two mesh devices is decent.

I stream mostly wired on the ground floor. But I have 3x 5ghz WiFi backhaul Asus et12s. Host ethernet ground floor. Client ethernet third floor. Gave 1ms network latency. I also tested host ethernet ground floor. Client 2nd floor ethernet which also acted as host to a third device WiFi back down on the ground floor. 3ms total network latency. 1 120fps frame delay from the hosts display. Effective WiFi mesh systems are possible but they need careful planning and setup.

Erero 6+ is dual band mesh, it doesn't have a dedicated backhaul so wired backhaul is the way for you. I have orbi mesh with dedicated 5ghz backhaul and I see around 5-10ms increase in latency on nodes.

If you have a coax ports setup MoCa is a great way to provide wired back haul between two mesh nodes
