Hello.I finally solved the problem. I just detach and re-attach the wifi card physically and it worked. First, I updated BIOS and nothing changed. Then I made several changes to BIOS configuration. I found that I've installed for legacy BIOS and MBR. So I reinstalled OpenBSD for UEFI and GPT. But the problem was not solved. And at this morning, I recalled that I could use this wifi from Linux. So I tried to boot from Linux live USB(Debian), and encountered a similar problem of iwlwifi with error code -110. I googled for this problem and found an article: https://bugzilla.kernel.org/show_bug.cgi?id=205299 It implies that the problem has something to do with Windows. Actually I installed Windows on this machine and my sister used it until I installed OpenBSD last week. I wondered if I could reset some configuration on the wifi card made by Windows by disconnecting it from the motherboard. And this worked for me. Anyway, thanks a lot everyone. Matsuda Kenji
I recall something similar but with ethernet. Basically on windows "shutdown" is more like "hibernate" to give you faster boot, unless you explicitly disable this feature. You can check this in task manager if uptime after shutdown and power on is not as low as you would expect it to be. This does not apply to reboot.
So when i "shutdown" windows and on next boot went to linux, NIC was not working. The solution was to do "reboot" on windows then boot to linux.
This was in 2016 or 2017 I think, I can't test if that's still the case because I no longer have windows installed. I also can't remember if this was on old motherboard (realtek NIC) or new motherboard (intel NIC)
