Dear TP-Link Technical Support Team,  (11-04-2026)

I am a long-time enthusiast of your products and currently own your flagship router, the Archer BE900. My home infrastructure is built on a high-end 10Gbps backbone, utilizing Category 8 cabling, 10G switches, and multiple EasyMesh nodes to support a high-performance Home Office environment.

I am writing to express a significant technical concern regarding the current Multi-WAN implementation in the firmware. Currently, when enabling a second WAN, the system forces the user to utilize the second 10Gbps port.

For high-end users, this creates a major bottleneck for the following reasons:

1. Sacrificing the Main LAN Trunk: By forcing the second 10G port to act as a WAN (often for a secondary ISP link of only 1Gbps or 2.5Gbps), we lose the 10Gbps backhaul to our main switch and the rest of the local network.

2. Underutilized Hardware: The router features dedicated 2.5Gbps ports that are perfect for a secondary WAN. Using one of these for the second ISP would allow us to keep the 10Gbps port dedicated to the LAN, maintaining the high-speed integrity of our internal network.

As a loyal customer who invests in your flagship hardware, I kindly request that you consider a firmware update that allows manual selection of any port (specifically the 2.5Gbps ports) as the secondary WAN. This flexibility is essential for a router in this price range and category.

Multi-WAN error; only allowing WANs to use 10GE ports is a mistake.

I look forward to hearing if this improvement is on your current development roadmap.

Best regards
