Phone USB tethering

[BeachGuy]

ISP connection went out today. Trying to get correct settings for tethering phone to USB for phone failover(?). GT-AX6000 running Merlin 3006.102.4. It seems to enable USB mode in USB application: 3G/4G(?). Then under WAN: Dual WAN, enable Dual WAN, 2.5G WAN primary, USB secondardy as failover? That didn't work. I noticed when Dual WAN is disabled, primary WAN is 2.5G WAN, the next line shows "4G / 5G Auto Mobile Tethering Yes/No". This doesn't show up when Dual WAN is enabled. Yes I read ASUS doc but it didn't help.

I purchased a USB-C to ethernet adapter. I think you connect the phone to that and then the ethernet into the 2.5 WAN port, enabling the "4G / 5G Auto Mobile Tethering (Yes)". I will test this weekend.

@BeachGuy, see the following (if you haven't already) Asus Support document on How to set up a smartphone to share the network to the router (USB Tethering). It may, or may not be relevant to what you are trying to achive.

Yes that is relevant and I figured it out. Under the USB settings there is no "Android phone", only "auto" and "legacy" (I chose auto). Also APN configuration, auto or manual. I previously had on auto but chose manual, USA, Verizon (even though Spectrum Mobile they use Verizon backbone) and left the rest as is. Thanks for your help!

When I tested this (a few years back) all I did was enable USB tethering on my Android phone, connected that to the Asus router over USB and it just worked,

Ok thanks. I got it working by enabling usb modem/usb tethering. That enabled dual wan with the phone as failover

I am looking at doing this.

Can you tell me, once you have configured it, can you just disconnect the phone, and the Asus Rotuer is OK?

The reason I ask this is because I want to perform a trial run, to set everything up, then would ideally like to just plug and unplug the phone to the USB port as needed, without having to set anything in the router.

My own experience with using a failover modem on an RJ45 is that it should be fine - but you never know! I thought I would ask!

Yes. It just shows as Not Connected.
