If you’re having issues with your home internet and urgently need a connection for work or some other reason, or if yet another outage has flat-out taken down your connection, there’s a way to get your router back online and reconnect all your devices to the web.
You can connect your phone to your router via Ethernet or USB and use it as a mobile hotspot for all the devices connected to your router’s Wi-Fi network. Personally, I recommend taking the Ethernet route because it should work with most routers, and you can use a powered USB dock to charge your phone while using it as a hotspot. That said, you can also use USB tethering if your router comes with a USB port and supports Android or iPhone tethering over USB.
All you need is a USB-C-to-Ethernet adapter, a phone, and a router
Plug and play, in most cases
When I first tried using my phone as an Ethernet hotspot with my old router, it didn’t work for some reason. The router was a basic ZTE Wi-Fi 5 model provided by my ISP, so it may have had custom settings that didn’t play nicely with my phone’s mobile hotspot feature, and I didn’t want to factory reset it. However, after I upgraded to an Asus RT-AXE7800 (a pretty solid budget Wi-Fi 6E router), I made it work without any issues.
In general, plugging your phone into your router via Ethernet and using Ethernet tethering should work with most modern routers, but your mileage may vary. If your main router is provided by your ISP and it ends up not working, you can try this with an old router you have lying around, a travel router if you own one, or even a router you’re using as a wireless access point.
Plugging my phone (a Google Pixel 10 Pro) into my ASUS RT-AXE7800 via Ethernet worked like a charm. All I had to do was unplug the LAN cable coming from my ONT (optical network terminal) from the router’s WAN port and plug the Ethernet cable connected to my phone into the same WAN port.

USB-C/A
Plugable’s universal plug-and-play USB-C/A 2.5G Ethernet adapter brings multi-gig networking to any computer you plug it into. Compatible with macOS, Windows, ChromeOS, and even iOS, this Ethernet adapter is perfect for adding Ethernet to a computer that doesn’t have it, or simply upgrading your system with multi-gig networking. It also is compatible with everything from Thunderbolt 5 all the way down to standard USB 3.0.
Then I went to Settings > Network & internet > Hotspot & tethering and enabled Ethernet tethering (the exact path may differ slightly depending on the Android phone). It took a few seconds for the router to recognize my phone, and after that I had no issues connecting to the internet over Wi-Fi on my partner’s Samsung Galaxy A52s. That was pretty much it. I didn’t have to change any settings or set up my Wi-Fi SSIDs again; it was all plug and play.
I used a UGREEN Steam Deck dock to do this, but you can use any USB-to-Ethernet adapter or USB dock. However, I recommend using a powered USB-C dock like mine because that way you can charge your phone while using it as a hotspot, since Ethernet tethering can quickly drain its battery.

You can also share mobile data with your router via USB tethering
If your router comes with a USB port and supports Android or iPhone USB tethering
If your router has a USB port, there’s a good chance it supports receiving an internet connection from a USB modem, which, in this case, was my phone. All I had to do was plug my phone into the router’s USB port, activate USB tethering (Settings > Network & internet > Hotspot & tethering > USB tethering), and the router automatically accepted the phone’s internet connection because the WAN cable had already been unplugged.
If it hadn’t been unplugged, I would’ve had to manually activate the Secondary WAN (USB) option in the router’s admin panel. On my router, the USB modem option was enabled automatically, but if you also own an ASUS router and USB modem mode doesn’t activate as soon as you plug your phone in via USB and enable USB tethering, you’ll likely have to enable it manually. Just go to Network Map, click the USB icon, and then open USB Modem Settings.
Once there, enable USB Mode and hit Apply. My router automatically selected my phone as the default USB device, but if yours doesn’t, you may have to manually select your phone from the list of available USB devices. The download speed was about the same as over Ethernet, around 190Mbps.
If your ASUS router uses different firmware, you can check out ASUS’ tutorial explaining how to activate USB tethering on various ASUS routers with both iOS and Android devices. If you own a router from another brand with a USB port, consult the user manual or look online to see whether it supports USB modems or USB tethering.

I didn’t expect this to work this seamlessly
After I couldn’t get my ISP’s router to work with my phone over Ethernet, using your phone as an internet source for your router—and thus your entire home network—started sounding too good to be true.
But after trying it out with a router I bought myself, I couldn’t believe how simple it was to use my phone as the internet source for my entire home. The next time your internet goes down, you know what to do.
