Tether not active

I have a brand new GL-MT300N and have upgraded to the 2.25 firmware. I purchased this so I could use the USB Tether feature of my cell phone to create a wifi network (the reasons why I don’t just use wifi hotspot on the cell phone are as valid as they are boring. Please just take it on faith that I need this.)

I have tested this cable with this TMOB Samsung S7 and usb tethering to a PC works fine.

This seems like a very simple use case. It also simply doesn’t work. With a PC plugged into the LAN port and my cell phone set to Tether the USB port Tethering Interface does not come up.

The System log actually looks like it works. But it is never assigned an IP address.

I also tried the instructions at OpenWRT wiki USB Tethering to an OpenWrt router [Old OpenWrt Wiki]

They don’t really offer anything new and didn’t make anything any different:

root@GL-MT300N:~# uci set network.wan=interface

root@GL-MT300N:~# uci set network.wan.ifname=eth1

It feels like I’m missing something simple. But I am at a loss for what it might be. Any help appreciated.

Does Samsung S7 need to use easytether?

No. Tethering works fine and I get 8GB a month for free. I’ve never come anywhere close to that.
