Idualwifi7260 failed to initialise

If the first time you tried last version it was after updating your old install, then it’s probably that an init script or a config file wasn’t updated.
When you did a clean reinstall, you got rid of that problem.

No, shortly after I encountered this problem, I uninstalled Haiku on my laptop and switched to Linux. I did a clean installation with UEFI yesterday, the WiFi still not working. Today I tried to clean install with MBR and now it works!

I have not tried in UEFI mode, but the idualwifi7260 works very well for me on a ThinkPad E540 when booting in BIOS mode. :+1:
