Deco BE95 Mesh ignoring Wired Backhaul, slowing performance
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
TL;DR Only the MAIN Deco BE95 uses a wired connection, any remote Mesh routers, including devices with wired connections to the remote and the backhaul all use Wireless regardless of what the app show, and in the case of Wired connections >= 2.5Gbps, it is slow with added latency.
Topology:
1Gbps Fiber Internet _> Cat8 _> OPNsense 23.1.9 Router w/Intel i225V NIC _> Cat8 _> Netgear MS108EUP 2.5Gbps Switch _> Cat6 RJ45 throughout house _> Deco BE95 in AP Mode using 10Gbps port above SFP w/1 Remote Mesh BE95 (bought the 2-pack).
All testing between local LAN systems using iperf3 on FreeBSD 13.1-RELEASE-p7, Windows 11 22H2 x64, and MacOS Ventura 13.4.
Issue:
App indicates Wired Ethernet backhaul, however testing shows no backhaul traffic using ethernet.
In addition, wired connections to remote non-main AP are also using Wireless backhaul instead of local Wired ethernet backhaul over Cat8 cable to RJ45 wall connector.
Wired Ethernet Backhaul with a 2.5Gbps negotiated rate should supersede wireless unless Wireless negotiates >5Gbps.
Latency backs this up as well with pings >=4ms Wireless vs. <=1ms Wired
Recommended solution:
Allow service order / NIC metric to be set to force an order of precedence for backhaul between mesh systems. Also allow manual setting of backhaul preference between Wired/Wireless/Auto
LAN Testing:
Deco BE95 Mesh #1 Main Setup in AP Mode connected to 2.5Gbps Ethernet backhaul via included Cat 6 cable directly to 2.5Gbps switch over cat6
Deco BE95 Mesh #2 Connected via Cat8 cable in 10GBps port above SFP to 2.5Gbps
Wiring to switch over Cat6 < 75 feet at longest run
