Are there any router with 2.5Gbps LAN port?
Are there any router with 2.5Gbps LAN port?
With Single 2.5Gbe LAN port:
Asus RT-AX11000 and RT-AX86U
NETGEAR Nighthawk AX12 RAX200
Take note there are routers with 2.5Gbe WAN only (not LAN) which is useless with SingTel ISPs, eg, TP-Link AX11000 and AX6000.
If you want to play with DIY router and want to take risks, Taobao has one interesting 4 port 2.5Gbe router on pre-order. I am quite interested in it but I do not want to take risks because of the pre-order. Rather I will wait and see the review first.
Intel J4125 CPU, 4 ports Realtek 8125B 2.5Gbe

QNAP has quite some 2.5Gbe solutions, like switch and NAS. Hopefully they will have a cheaper router with 4 x 2.5Gbe WAN/LAN ports as well.
i do want 2.5G switch but cant find any in stock. qnap 10g switch is also between $200~400 in amazon.
does the ugreen disconnect on heavy use?
I've heard even the Intel 2.5GbE NICs are flaky.Still the seller also says Intel 2.5Gbe card is better.
BTW, if you are into pfsense (FreeBSD based), here is the instructions for Realtek RTL-8125B FreeBSD driver installation.

Windows 10 has built in smb multichannel.
Just buy 2x cheap usb 3 gigabit adapters and connect to your gigabit router/switch. don't need to configure anything like teaming. As long as both source and destination computers each have 2 ethernet plugged in, the transfer speed will double
Nice, kind of cheap 2Gbps network.
Linux supports 802.3ad LACP based Link Aggregation.
http://linux-ip.net/html/ether-bonding.html
macOS has built-in support of 802.3ad LACP based link aggregation as well.
https://support.apple.com/en-in/guide/mac-help/mchlp2798/mac
***
macOS uses the Link Aggregation Control Protocol (LACP) to negotiate the link aggregation. LACP must be supported on all link aggregation devices involved.
Many managed switches have an upper limit of 4 or 8 ports in an 802.3ad aggregated bond. macOS does not impose a limit to the number of physical ports that you can add to a bond.

if source and destination pc is windows 10, dont need managed switch with lacp. can use existing equipment. windows will manage the traffic for you.
can u try file transfer between your 2.5G adapters? can it sustain 230MBps or faster?
Just set up an SMB share from my Mac Mini M1 and then copying from the Mac Mini to my Acer Swift 3 laptop, with three Ubuntu 20.04 AMD64 ISO files total 7.78GB. It can only sustain about 1.8Gbps.if source and destination pc is windows 10, dont need managed switch with lacp. can use existing equipment. windows will manage the traffic for you.

On the other hand, this is probably due to the slow speed of the Acer Swift 3 laptop (bought in Dec 2017, Core i5-8250U CPU, 8GB RAM, 256GB SSD).Just set up an SMB share from my Mac Mini M1 and then copying from the Mac Mini to my Acer Swift 3 laptop, with three Ubuntu 20.04 AMD64 ISO files total 7.78GB. It can only sustain about 1.8Gbps.

thanks for testing! so getting another usb gigabit adapter is an alternative to getting 2.5gbe adapter for windows users who do not want to change to 2.5g switches.
but for non windows users have to get 2.5G adapter for faster transfer speed as smb multichannel may not work
Actually 2.5Gbe adapter is pretty cheap as well. Ugreen is already on the high side but there are many cheap alternatives from Taobao, especially for desktop with PCIE.
TP-Link TL-NG421 is at RMB89 or about S$18 only.
