Hi. I expect the answer is here somewhere but what I've seen seems to be people with no internet connection.
I am connected via WiFi but keep getting the System message "connection failed
Activation of network connection failed.
Seems to be "p2p-dev-wlp2s0 wifi-p2p disconnected " ? I don't know what that is.
Can someone point me in the right direction please?
Hi and welcome.
Looking at your screenshot looks like you are using a 4g router/Data SIM from Vodafone. Which is it?
Hi. Thanks for the quick reply.
I have Vodafone 500 Broadband on a 3rd party TPlink router.
I did a quick Brave A.I. search on this (Zorin 18 is a fork of Ubuntu 24.04 hence latter used in search criteria):
" The device name p2p-dev-wlp2s0 with the type wifi-p2p and state disconnected is a standard Wi-Fi Direct (Peer-to-Peer) interface created by your wireless adapter, not a cellular modem interface. This specific entry typically appears alongside your main Wi-Fi adapter (wlp2s0 ) and is often harmless, as it represents a separate channel used for direct device connections rather than internet access.
If you are attempting to use a Vodafone data SIM (cellular modem) on Ubuntu 24.04 and cannot connect, the issue is likely that the modem is not being recognized or is blocked, as the p2p-dev interface does not handle cellular traffic. In Ubuntu 22.04 and later, users have reported that certain cellular modems (such as Quectel EG-25G) require an FCC unlock or specific configuration in ModemManager to appear as a gsm or wwan device, which is distinct from the wifi-p2p interface.
To resolve the connectivity issue, you should:
nmcli dev to look for a device type listed as gsm , wwan , or cdc-ether rather than wifi-p2p .ModemManager tools or specific commands provided by the manufacturer, as newer Ubuntu versions do not automatically perform this unlock.dmesg or lsusb before attempting to connect.AI-generated answer. Please verify critical facts."
Although the "Wired" option in the taskbar was greyed out I activated it then deactivated it again and now "ethernet" is showing disconnected and the message has stopped.
Maybe that's a little glitch?
You posted again before having a chance to read my previous post. Please take a look.
I tried Smarty SIM in a USB dongle a while back but connection ceased come the afternoon so I gave up on that.
Thanks. I'm on a Fibre landline, Vodafone is just the provider.
I found toggling the "Wired" switch has fixed it for now, not sure what will happen next time I start up.
I've restarted now and the "Wired" button has gone completely
It used to be above Wi-Fi. So.... Seems to be fixed now?
I would say yes if you need in future to use wired you may have to do to wifi like ya did to wired
Have you tried booting into an older kernel? My ethernet behaved similarly when I updated to Zorin 18.1 from 17.3 where I was using 6.8 and as soon as I went back to 6.8 through the advanced options, the ethernet started working normally again.
