2.5G WAN is a bonus, not the main selling point.

Here are some cases that 2.5G WAN is useful.

  • You can use drop-in gateway mode, which only need wan and 2.5G wan could be a benefit.
  • You can connect storage on USB3.0. The USB read speed exceed 1Gbps so 2.5G is useful
  • Make it possible to extend other USB3.0 applications, e.g. USB to Ethernet, USB modems, USB wifi dongle etc. Of course these applications is not yet tested.

Overall, 2.5G is better than 1G.

Why don’t way put two 2.5G in the the case? It is trade off of some factors.
