Connect android phone to WAN port of router (not lan) I would like to connect my phone to a router so that I can share its internet connection among the devices in my house. How do I connect the phone to the WAN port of my router so that the router is 'getting its internet' from the phone? Will a normal microusb to ethernet adapter do it, like this one? (http://www.ebay.co.uk/itm/Micro-USB-5-Pin-10-100-Mbps-RJ45-LAN-Ethernet-Adapter-for-Tablet-PC-S6-/321629022330?pt=UK_Computing_USB_Cables&amp;hash=item4ae295687a) 

I have a tethering plan, and a spare phone I am not using, which is why I am doing it this way and not with a dongle and usb router. Some of the devices I want to connect don't use wifi or will just work better with wired connections, which is why I want to attach the phone to the router via a cable.
I got this working today. I bought an Asus RT-AC68P router. It works out of the box. I just connected my phone to the router's USB 3.0 port using a normal phone usb cable (same one used for charging, etc.).

All Asus routers have the same firmware, so this should work "out of the box" with any new-ish Asus router.

I am not impressed with the Asus setup procedure when using a USB 4G modem/phone for WAN, but I ultimately got it working. I prefer working with dd-wrt myself.

This functionality is supposed to work with dd-wrt too, but today I also purchased a BUFFALO AirStation AC 1750 DD-WRT Router (WZR-1750DHPD) with firmware "DD-WRT v24SP2-(8/12/14) std" and I could not get it to work. I will try a newer or different version of dd-wrt in the near future.

  "I can recommend Kong Mod to achieve this. Works right out of the box,
  at leastt for me. I recently lost my wired internet connection and
  used a 3G dongle as backup. The only thing I did was to plug in the
  dongle, select '3G/4G' as Wan connection and filled in the APN.
  Everything worked directly, no additional modules to load. Success or
  failure is of course dependent on the dongle being supported."
