[arch-general] Interesting Dual Boot Problems
Hello, I installed Windows 10 recently, and now I am having wifi issues. On the Windows side, the campus wifi will connect, but it will show that there is no internet connection. Booting in to Linux causes pings to fail with temporary failure in host resolution, and ip link shows that the wifi device is down. Doing sudo ip link set dev wlp3s0 up has no effect; from what I can tell, it is stuck in a permenant down state. dmesg reports that the "link is not ready". I've tried restarting the netctl profile for the campus network, restarting dhcp, resetting the pci device, but alas, things seem to be very broken. I am using a Killer n1525 network card. Has anyone else had a similar issue, and if so, how did you resolve it? Thanks, Hunter

Hunter Campus wifi is usually wpa enterprise which I've always had trouble with. I don't know how installing windows could cause this or how to fix

eduroam and other wpa2-enterprise work for me. Do you have a means to try your config with another laptop/network card? -- GPG fingerprint: 871F 1047 7DB3 DDED 5FC4 47B2 26C7 E577 EF96 7808

I do not have a spare laptop or network card. Everything was working perfectly fine before I installed Windows, so I have no idea what is going on here.

Interesting. Maybe windows turned something off? Broken power saving feature that turned off something in the card maybe? -- GPG fingerprint: 871F 1047 7DB3 DDED 5FC4 47B2 26C7 E577 EF96 7808

This could be the case. The only option under power management for the network card is "Allow the Computer to Turn off the Card to Save Power", which was turned on by default; I turned that off to no effect on the Arch side.

What does "rfkill -list" say? Some Win driver soft block the wifi card upon restart/shutdown.
Nothing is being soft blocked when I ran rfkill this afternoon. A second reboot still shows the same result. On 4/10/18, Marco via arch-general <arch-general@archlinux.org> wrote:

Just a thought: Maybe windows changed some BIOS/UEFI setting without asking you triggering a power management or similar bug? On 10.04.2018 19:46, Hunter Jozwiak via arch-general wrote:

Does it make a difference if you choose reboot in Windows vs shutdown? Windows 10 hibernates by default (hybrid shutdown) when powering off. Reboot uses a 'real' shutdown. Mvg, Guus Snijders

No. Rebooting from Windows to Linux still causes the issue. Rebooting from Linux to Linux causes the issue, and shutting down the system doesn't help either.

This is a really important issue with Win10 -- especially with dual-boot. Unless you choose "Restart", Win10 doesn't fully shutdown. The windows driver could leave the card in a state that Linux cannot manage the card. One option is to use the button or switch on your laptop to turn wifi off before using "Restart" and then turn it back on once the cold-boot occurs. I have an HP Laptop that is a dual-boot Arch/Win10 box (it has 2 separate hard drives) and I haven't experienced this problem with an Intel wireless chipset. Those are the only stray thoughts I have on the issue. If a cold-boot is occurring when switching between OSs, then neither can have any effect on the other (at least with a MBR setup). -- David C.

Manufacturer windows driver can turn off network card using proprietary functions. Linux is unable to undo that. That setting is hidden in device manager , device , driver details or similar. Not sure where that can be found in win10, but changing it there is only way to be sure it's disabled. Higher level options to set it are usually only temporarily.
