Tethering on Fedora-43

chrisofbristol · February 16, 2026, 12:43pm

I’m in a gap between 2 broadband contracts, so i switched this on and all the indicators suggest that it is working - but there is no Internet access.

My Android-12 phone has 3 relevant options:

Bluetooth tethering. (less secure/rugged)
USB tethering.
Ethernet tethering. (no adapter)
I chose USB tethering as I was using a USB cable.
Fedora has:
Settings > Network > USB Ethernet.
Note the mention of Ethernet, there’s no option that doesn’t mention it. Is straight USB connection not possible? Ebay sells USB/Etherley adapters for under a fiver, is that what I need?
The gear wheel next to USB Ethernet takes me to several tabs with options that don’t mean much to me.

Fedora-43 Linux 6.18.7-200.fc43.x86_64

If the usb cable is connected and your handy has usb tethering switched on, you should see an option in

lsusb

Bus 001 Device 004: ID 04e8:xxxx Samsung Electronics Co., Ltd Galaxy series, misc. (tethering mode)

 nmcli c

NAME           UUID                                  TYPE       DEVICE    
USB-tethering  xxxx-xxxx-xxxx-xxxx  ethernet   enp0s20u1 
lo             xxxx-xxxx-xxxx-xxxx  loopback   lo

Do you see something like this?

Tested with 6.18.9-100.fc42.x86_64 & 6.18.9-200.fc43.x86_64

I can see a list, one member refers to my Samsung handy.
Bus 002 Device 012 ID xxxx:xxxx Samsung… (tethering mode)

ilikelinux · February 16, 2026, 1:59pm

And nmcli connection does it show it too?

chrisofbristol · February 16, 2026, 2:02pm

That shows
Profile 2 [long number] Ethernet enp0sxxxxxx
Settings > Network > USB Ethernet is Connected

ilikelinux · February 16, 2026, 2:03pm

And in the terminal can you ping a dns as an example? I use 1.1.1.1 maybe you use 8.8.8.8 ?

Also test ping google.com

All 3 list

chrisofbristol · February 16, 2026, 2:07pm

Curl https://example.com says failed to verify the legitimacy of the server…
Curl -k lists some html

ilikelinux · February 16, 2026, 2:12pm

You might try www.example.com or example.com

You made a typo …

chrisofbristol · February 16, 2026, 2:13pm

Not in the terminal

ilikelinux · February 16, 2026, 2:16pm

curl -k example.com
<!doctype html><html lang="en"><head><title>Example Domain</title><meta name="viewport" content="width=device-width, initial-scale=1"><style>body{background:#eee;width:60vw;margin:15vh auto;font-family:system-ui,sans-serif}h1{font-size:1.5em}div{opacity:0.8}a:link,a:visited{color:#348}</style></head><body><div><h1>Example Domain</h1><p>This domain is for use in documentation examples without needing permission.

It seams to work … so what else you wanted to know about tethering?
If you just have a gap from a few days, I am not sure if, to invest more time and money, makes sense.

ilikelinux · February 16, 2026, 2:19pm

Still no access ?

Are you on Gnome?

chrisofbristol · February 16, 2026, 2:25pm

But the browser doesn’t…
6 weeks without broadband.
And I was about to upload a completed package to COPR. And I have trouble with an account to sort out. All of which is a nightmare to do from a mobile.
I’m on Gnome.

ilikelinux · February 16, 2026, 2:28pm

I see … tell me what the browser tells you when accessing example.com ?

I am testing with Gnome and did deactivating my main Ethernet. Just working as you like to, without issues to browse!

ilikelinux · February 16, 2026, 2:34pm

I tested with F43 and 6.18.9-200.fc43.x86_64, can you update your system? Or does this also not work?

Video tutorial — COPR documentation > CLI access to copr.

grumpey · February 16, 2026, 2:43pm

Can you check.
resolvectl status
resolvectl query fedoraproject.org

You may also want to check: ip address show

chrisofbristol · February 16, 2026, 2:56pm

Example.com is OK but the “Learn more” link fails with
This site can’t be reached
www.iana.org’s DNS address could not be found

ilikelinux · February 16, 2026, 3:00pm

You might still have routes from the old broadband connection somwhere … try to flush the caches.

sudo resolvectl flush-caches
