What happen when your home Internet is down and won’t be available for a while?
Internet has become part of our daily life. Many of our activities involve Internet access. From gaming, online shopping, banking, searching for information and etc. Simply put, it’s really inconvenience and tough when home Internet is not available.
I once had a power outage for several days because of a winter storm. Of course there were no Internet during power outage. The trouble was, there were still no Internet access after power was restored. And it would take ISP provider a week to have their technician came and restore the Internet. Those were the time when you realize how connected we are to the Internet. Without Internet, it has become a huge inconvenience and disrupting our daily routines.
Tethering mobile phone to home network
If you have unlimited data plan and strong signal with your mobile phone, it probably would be a great backup Internet connection for your home. What you need is a router that supports tethering mobile phone. With proper settings, your home network can then connect to this router instead of the ISP router and boom, your home network now has Internet access again.
For some, wireless Internet (using a hotspot wireless device from wireless carrier) may even be a viable option to serve as your primary home Internet connection. It all depends on the availability, pricing, signal strength and stability at your area.
The router I used is ASUS WiFi Router RT-AC3200. It’s a solid router that serves me well mostly as a wireless access point for a couple years. And when needed, paired with my mobile phone to serves as a secondary Internet connection.
There are 2 ways to setup this router to provide Internet connection: usb tethering using router mode or hotspot connection using repeater mode.
Quick note: Wireless carriers may have restrictions on what protocols are allowed. Some services, especially those that require port forwarding may not be working properly.
Preparation
You would need the latest firmware to have a stable connection and repeater mode method is only available with the latest firmware. Please update your ASUS router to latest firmware first, if needed, before proceeding.
We need a computer to connect to the ASUS router to configure the router. The default IP address of the router is 192.168.1.1. If the IP address is different, login to the router, and manually set the IP address back to 192.168.1.1.
Next is to set computer’s IP address manually to 192.168.1.100 so that they can communicate to each other.
- In windows 10, go to Windows Settings > Network & Internet > Change adapter options
- right click on the Ethernet adapter, then Properties
- select Internet Protocol Version 4 (TCP/IPv4) and click on Properties
- Set the static IP address as follow and the click OK.
Optionally, you can use the command ipconfig at a command prompt to verify that the network adapter is assigned the IP address 192.168.1.100 correctly. We can switch back to ‘Obtain an IP address automatically’ once the setup of the switch part is complete.
Both the router & the computer should be isolated from your home network now. Disconnect them from home network. Then connect the computer directly to this router and login to the router at 192.168.1.1
Method 1: USB tethering using wireless router mode
This method only works for android phones, doesn’t work for iPhones.
If the operation mode is already in ‘Wireless router’ mode, you can skip the next sub-section. Otherwise, we need to switch it to Wireless router mode first.
Switch to Wireless router mode
- go to Administration > Operation Mode
- select ‘Wireless router mode’ radio button
- click ‘Save’
- wait for the router to update its settings
- login to the router again and it will do the ‘Quick Internet Setup’
- select No for ‘Does your Internet connection require user name and password?’ and click ‘Next’
- then select ‘Automatic IP’ and click ‘Next’
- Next is Wireless Setting. Just keep your previous settings or quickly enter one. click ‘Apply’ when done.
- Click ‘Complete’
Your router should now be in ‘Wireless router mode’ as shown below.
Connecting the mobile phone
now connect your mobile phone to the top USB port of the ASUS router. Allow permission if your phone requests for permission. Now refresh the browser and your phone should show up as USB device. Turn on USB tethering at your phone.
- go to USB Application > 3G/4G > Internet Connection
- turn on ‘Enable USB Mode’
- select ‘Android phone’ for ‘Select USB Device’
- click ‘Apply’
- wait for Applying Settings and then login again.
The Secondary WAN should show as ‘Connected’ as shown.
Method 2: Hotspot using repeater mode
This method should work for both android & iPhone. Turn on mobile hotspot on your cell phone first.
- go to Administration > Operation Mode
- select ‘Repeater mode’ radio button
- a list of available SSIDs should appear. select your mobile hotspot.
- enter the mobile hotspot’s password, then click ‘Connect’
- ‘LAN IP Setting’ screen will show up. Let it obtain info automatically. Simply click ‘Next’.
- Next is Wireless Setting. Just use default settings or quickly enter one. click ‘Apply’ when done.
- wait for the router to connect to the hotspot
Once the router finished connecting, your computer should be able to connect to the Internet. However, the router will obtain a different IP address from the mobile hotspot. As a result, you would need to find the IP address in order to connect to the router’s configuration webpage. For android, you can find the router’s IP address at the cell phone hotspot’s connected device. For iPhone, however, there’s no information about that. You would need to use a network scanner or ASUS device discovery utility. Or when you disconnect the mobile hotspot, the router will reset it’s IP address to 192.168.1.1.

16 Jun 2020The key here is to go to phone info and find the build number click on it 7 times and turn on the usb debugging. Then you can go to tethering with usb and then you can can connect to the router

7 Sep 2020This worked flawlessly (I have the same router) and saved me after lightning killed my cable modem. I had been curious about this for years – thanks very much for this.
Alan Chan
7 Sep 2020Sorry to hear that your cable modem was fried but glad that this guide is helpful for you. Cheers
Steve
16 Sep 2020I didn’t see the 3G/4G > Internet Connection, what should I do?
Alan Chan
16 Sep 2020The probably mean your router doesn’t support it. Double check with your router’s manual.
Q
27 Sep 2020thank you for the explanation. can you advise which router you used for usb tethering? i know you said ASUS WiFi Router RT-AC3200 but your screen shots (GUI) shows RT-N66U?
Alan Chan
27 Sep 2020Good eye. Ha ha. I have both RT-AC3200 & RT-N66U and both work.
RT-AC3200 is newer model that why I mention it in the post. But apparently I took screenshots while working on RT-N66U instead.
Alan

9 Jun 2021I tried this with my N66U recently. Problem I had was when I changed the USB mode to 3G/4G modem it did some sort of reset, and my Android phone Galaxy S7 turned off USB tethering. I turned it back on but then had to do a reset of sorts on the router (working off memory here), and it seemed like an endless cycle.
Rob
6 Oct 2020Is there an WiFi 6 router equivalent that you would recommend that supports hotspot tethering via mobile phone? Also, is there a particular advertised feature on routers that I could look out for that supports the mobile tethering function? Thanks.

10 Oct 2020I’m interested as well!

26 Oct 2020So I bought the ac3100, Asus says the only phone that will tether is the note 4…are you kidding me. How do you get around this stupid issue?
Alan Chan
1 Nov 2020The tethering setup was tested against S8. So definitely more phones would work.
But technology is changing with new phones, new Android versions, new routers.
The only way to find out if it works for your phone and router is to try it out. cheers.

30 Nov 2020Does anyone know if USB tethering works on the ASUS RT-AX58U WIFI 6 router ? The interface looks very similar to RT-N66U but I didn’t find much online.
Alexandre G
9 Jan 2021I just tried on a RT-AX58U with a xiaomi mi 9t pro and it didn’t work… When I connect my phone to the router via USB cable, it shows up as connected on the router web interface but as soon as I turn on the usb tethering on my phone it disappear, as if I disconnected it.. I tried several things but If someone as an idea
KathyW
29 Dec 2021Yes, it works on the ASUS RT-AX58U. I just purchased this router yesterday and set it up to tether my hotspot and it works! Now I just need to figure out the settings to get my smart devices that run on 2.4G to connect and work. I will also try to use my Zen WiFi mesh as nodes to extend the signal.
Gizmo
20 Jan 2022I have been using the RT-AX58U for USB tethering to my Netgear Aircard 797 hotspot very successfully for a year or so. It started disconnecting from my hotspot a couple of weeks ago, though. My hotspot works on 4G/LTE cell service (data only) and has a consistent signal. I have done a firmware update on the router, checked for firmware updates on the hotspot, completely reset the router, checked the USB cable from the hotspot to the router, etc. The router keeps randomly disconnecting the hotspot connection (light turns red) and I have to go in to the router settings and set it all back up. Sometimes I have do do this a couple of times per day, other times it will stay connected for a few days at a time. I am not a technical person and can’t figure out what the issue is. Until this started, I had absolutly no issues using the router for tethering my hotspot. The router has amazing range and I’ve been very pleased with it up to this point.
Pete
30 Nov 2020Thanks. Would some please add to the list of capable routers.
Rich
7 Dec 2020After tethering you a phone with this router, could you them set up a mesh WiFi system to cover your home?
Alan Chan
15 Feb 2021Technically yes. But you should check with phone service provider’s terms and agreements if tethering to multiple devices are supported.
Mark
19 Dec 2020I have a ASUS RT-AC86U with firmware updated and have followed the instructions above. Everything makes sense except my secondary wan is not connected. Any help would be appreciated.

10 Jun 2021Followed the instructions with the same router and it works great connected to the Samsung S21.
Alan Chan
23 Aug 2021awesome

12 Jan 2021The easiest way is just use your laptop and plug in to your USB port and then configure a hotspot that’ll give you update devices including your printer and it’s so easy and most people don’t even use their laptops anymore and everything’s done on the phone but you can tether two phones as many USB ports that you have you can tether to your laptop. I have both of my phones tethered to it and I’ve got some great speed going on plus my security system all runs off of my laptops hotspot so I don’t pay or run out of hotspot data from the phone I hope this is helpful
Chris
3 Feb 2021Hi Alan, I didn’t have to change my Internet Protocol Version 4 to login. Was able to follow your instructions to the end. But can’t get the Secondary WAN to show as ‘Connected’ as shown. (Says The network cable is unpluged) Help please. RT-ACRH12. 3.0.0.4.382_52107
Thanks for the great website.
Alan Chan
15 Feb 2021Different router has different firmware that could behave differently. You can check if your router has new firmware that may support tethering.
Steve
15 Feb 2021Can this be done with a tablet that runs on Android with data service?
I want to connect my tablet to the asus router and share its Internet, has anyone tried, will it work?
Alan Chan
10 Feb 2022try it.
David S. Greenberg
19 Feb 2021Amazing! Thanks so much! I had gone through all the hassle of setting up an old WiFi client device to the WAN port of my ASUS router to share my Visible connection. Didn’t know this was possible! Worked perfect on first try at setup. It eliminates another device in the chain. The only remaining problem is that the 5Mbps cap on Visible ends up being shared, so if 2 devices are active, they each get about half the bandwidth (i.e. 2.5 Mbps). Any ideas on how to overcome that?
Owlr
25 Jun 2021Changing tthe TTL of the router to 66 is suposed to mask the tethered status
Mike S
26 Mar 2021Hi Alan, I have already learnt so much from your great site! thank you.
Please could you advise on my particular requirement!
Can I tether an iPhone (using repeater mode) to an Asus RT-AC68U ( or any other modem/router that you might advise ) which has been enabled/configured for a VPN service?
My purpose is to use the VPN service to effectively disable Geotagging whilst streaming to my Apple TV box!!
Cheers again!
Alan Chan
1 Apr 2021Hi Mike,
thanks. Unfortunately, this tethering doesn’t work for iPhone.
Alan
George Redford
5 Apr 2021Thank you for the information, it was very enlightening, it would be advantageous if you could please reveal the firmware version that you have on your ASUS RT-AC86U router that functions perfectly please, I have just bought one and would like to ensure that the firmware is the same and will do as you say when I connect my phone.
Many Thanks in Advance
George

5 Apr 2021Sorry I made a typing error I meant to type ASUS RT-AC3200
Alan Chan
7 Apr 2021It has the older firmware running 3.0.0.4.382_50624.
Yours should have a newer firmware and I would expect newer firmware would work. Cheers Alan
Dave
30 Apr 2021Will this work with an AC1900 from T-Mobile, tethered to a Galaxy s7? I have a really old unlimited legacy plan through a major carrier and since I live alone, I’d much rather pay a little extra a month for hotspot capabilities if I can do this trick with the modem, than having to get dedicated hard line. I just wanna be able to play ps4 and all the stuff I need for school while having the flexibility of quickly unplugging/plugging up my phone whenever I leave or come back. The speed isn’t throttled anyways so hopefully it’d work.
Jim Ong
15 Jun 2021thanks, Alan. got this working on RT-66U. My RT-AC86U appears to have same options to configure so likely would work on it as well for those who may be interested.
Faust
27 Jul 2021Been using the Asus RT-N66U with a Moto G4 with Android 6 for about 4 years. Works great once I get it started. The trick to get it to work is to first boot up the router. After the router fully boots, connect the phone then turn on tethering in Android.
What I wish I could do is 1.) While tethered, transfer files to and from the phone to other devices on the network and 2.) Print from the phone while tethered. The phone is my household internet connection and I can’t untether to print or transfer files. Anybody know how to do that?
Ben
3 Aug 2021Hey Alan, just wanted to say thank you very much for this.
I stuffed around for ages trying to see if there was a way to do it and pretty much gave up.
But then came across this and after a few attempts finally worked it out, so thank you for taking the time to document this for us all to use.
Alan Chan
23 Aug 2021Awesome! Glad that its helpful to you.

9 Aug 2021Interesting solution. I went with an ethernet solution and directly replaced my modem with my cell phones. I got a USB2-Ethernet dongle and plugged my cell into the modem slot on my router vs USB tethering described in other comments. I left my home network router connections (two desktop PC’s, printer and wireless) alone. I alternate my Motorola Edge and Samsung Galaxy A32 5G phones. Both have a selection for Ethernet Hotspot (under Network Connections) that I now use. I didn’t have to reconfigure anything. Only issue is the phone likes to burn electricity while tethered and inexpensive USB2-Ethernet dongles won’t provide a charge. Longest I’ve been active is 14 hours and the phone got down to 20% so if you want to be online even longer you’ll have to spring for a more expensive USB2 multiple port device to keep your phone charged. This solution also uses Tethering Data, not your normal Unlimited Data. We currently use about 2GB a day and my current plan provides 40GB per phone so we’re good for now, with some extra if we decide to stream up to 8-10 HD movies a month. I was able to justify the extra expense of a tether friendly data plan by eliminating my cable provider. I no longer have any redundancy so I’m totally down if my cell provider has any issues. I wouldn’t recommend this as a standalone solution if I had a critical need for connectivity, but for everyday folks, this appears to be a good alternative to living with a greedy internet provider or not having the last mile of cable installed in your area. (Note: my wife isn’t a big cell phone user so I’m able to forward her phone calls to my phone while I use her phone (and tethering data) for 1/3 of the connect time. Your wife may have a different opinion about your tying up her phone so proceed at your own risk!)
KP
18 Oct 2021If you have a 3rd available cell phone that has tethering capability – even without a sim card in it – you can use it as a dedicated slave by hooking it up to your router USB slot and tether it to either yours or your wife’s cell phone.

3 Dec 2021Thanks Alan! I have the ASUS ZenWifi AC300 mesh system. Can I tether my hotspot to the main router of this system in the same way you described?
Alan Chan
7 Dec 2021Hi Kathy,
Go to your ASUS ZenWifi AC300 admin page and see if it has similar USB support.
Try it out if it does is the best way to find out.

17 Jan 2022Hi Alan, Great article I have just acquired an RT-AX56U which has the identical setup as shown in your clip. I have configured and successfully connected the router directly via LAN and USB tether to the internet, it work great…
Alas every time I try to WiFi tether via my mobile hotspot on my Galaxy S7 the secondary WAN on the router continually says I am using an incorrect AP Network password. I have reconfigured the mobile hotspot Name/Pswrd so many times. The router lists my hotspot as a selectable AP but after completing the setup and router reboot, I get the same password error.
Oh one other question if you do not mind. If the modem talks to my PC out of the box, do I still need to change the default Gateway address?
Can you advise and in advance tks for the assist?
Alan Chan
10 Feb 2022I haven’t tried Wi-Fi tether. I can only guess your password error issue may be your hotspot and AP are using different wi-fi security protocols.
If your PC can connect to the Internet without problem, then you don’t need to change default gateway address.

11 Oct 2022I posted a question but looks like it got removed?
I connected iPhone with lightning cable to usb 3.0 and 2.0 ports. It wasn’t detected.
Then I removed it and connected a 4G android tablet. It wasn’t detected either.
I connected flash drive in both ports and it was immediately detected so I know ports are working.
Router is asus rt-ac68u with latest firmware.
Any ideas on how to get an iPhone or android tablet connected to it?
Thank you.
Alan Chan
13 Oct 2022Doesn’t work for iPhone.
As for android tablet, ensure it allows USB connection.
Unfortunately, I don’t have 4G android tablet so not sure if there’s any difference that prevents it from being detected.
