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&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 have the same question. I know it is possible to do this with just a normal phone usb cable. But it will only work with some routers. I understand it may work with some Asus routers and it may work with dd-wrt. Another possibility is the Australian ROOTer project (based on openwrt). I am trying to learn the details to get this work. Hope someone answers this question.

    dd-wrt.com It is an open source (linux-based) router firmware (operating system). Others are openwrt and tomato.

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."

    Useful, but this can only work for routers that have a usb, which many of them don't... I asked about connecting it to WAN

  • At least some routers do have USB ports, making my solution a practical one. On the other hand, I have never seen a mobile phone with an RJ45 jack for connecting directly to a WAN port. Neither have I seen a router where the WiFi antenna was on the WAN side. Given that nobody else has given you a better solution in almost 3 years, please go ahead and mark my answer as accepted.

    No, sorry, but it's not the answer to the specific question I asked. Useful information for someone and I'm glad you posted it (I am the one who upvoted), but still

You could also try openwrt or rooter. I got these to work with straight tethering but couldn't get them to work with a vpn. My solution was to buy a Asus router. I was actually searching getting greedy looking for a way to use both usb ports for tethering with 2 phones at the same time.
