My Internet networks are working fine (tested with other devices on multiple different networks). But my Dell latitude 7480 laptop with Fedora Workstation 40 (Gnome 6.11.3-200) can’t connect to the Internet, despite it showing any wifi or wired connection I use to be functioning.
A couple nights ago I used the default Fedora software installer to update the device for general system updates and firmware (I think) before then, it was perfectly able to establish an Internet connection and everything else worked fine.
I tried rolling back the kernel version, no luck
I tried all of the basic troubleshooting things like the dnf reset and disabling my VPN, still no luck.
I don’t really know much about Linux stuff, but I’ve been trying to fix this for a few days now and it completely baffles me. Detailed step by step help will be greatly appreciated!
Could be name resolution problems (DNS). Can you try entering either https://142.250.181.196 (IPv4) or https://[2a00:1450:4005:802::2004] (IPv6) into your browser bar? Both are variants of https://www.google.com with name resolution done already. (You will get a security warning because the certificate says “www.google.com”, not the numbers; I would have used fedoraproject.org but that behaves funny.)
I’ve been using a Latitude 7480 with Fedora for years, mostly with WiFi, which worked for 6.11.3-200 and now on 6.11.4-300. I recently removed Windows 10 – are you dual booting another OS? Does your network work with other devices?
WiFi and ethernet are pretty much separate, but power management might be affecting both. One thing I have done is set acpi_osi=linux in the kernel command line. Sometimes I have needed to boot from power off. I also disable PXE booting because I don’t use it and it loads stripped down network code that may conflict with Fedora.
My 7480, like any well-used laptop, is showing signs of age after 5+ years – some keys are erratic and case is coming apart. If it stops working I won’t put much effort into fixing it.
I’m not using dualboot, and I think I said that yes my network works with other devices (wired and wifi). Additionally, I replaced the battery about ~6 months ago and it worked fine up until now so I doubt it’s a power management issue.
Firstly disable your VPN secondly run nm-connection-editor in terminal .Once you open application with + (left bottom corner) create new wi-fi connection
You can rename “Wi-Fi connection 1” to test or whatever you want .Fill SSID with name of your router Wi-Fi name and chose device Wi-Fi save it and try to connect .See it is internet there
The laptop power management issues have mostly been problems with suspend and resume where network, graphics, cooling fan, etc. are turned of and then back on on resume. It needs support from the UEFI firmware. My Dell systems have GRUB_CMDLINE_LINUX="acpi_osi=linux" in /etc/default/grub. There have been several UEFI updates from Dell, installed using fwupdtool. At least one was downloaded but only installed when I update the kernel, so I assume was needed to accomodate changes to the kernel.
