I have a similar problem with the 6.7 release which I just installed today on an 8Tb drive I'm using with my older ASUS laptop.
athn0 at pci3 dev 0 function 0 "Atheros AR9285" rev 0x01: apic 2 int 17 athn0: AR9285 rev 2 (1T1R), ROM rev 13, address 74:f0:6d:7a:42:7f Can't seem to shake it with a cold boot. However I have some interesting other effects. I have several wireless routers, one of which is quite old and doesn't even do wpa. It's a UBNT antenna that I use to broadcast around the farm. So without any password at all, even the old kind, if I ifconfig athn0 -wpakey ifconfig athn0 nwid UBNT dhclient athn0 That works fine. Now, I can also project wireless from my cellphone using wpa2. Sometimes it works and sometimes it doesn't. I don't know if it's after a cold boot of the laptop, but what does work for me it to just disable the hotspot from the cellphone for a moment, and then re-enable it. Then it works fine with the nwid I set up and the wpa2 password I require. However no matter what I do I can't get a connection to my farmhouse wireless router. It's a DIR822 Dlink. Of course I know that's a low end router. Recently they recommended a firmware upgrade, and since then I found that I was unable to set it up for no password, and had to add one, and then add that password to all the other devices in the house. Just now I saw that I can enable projecting a separate "guest" zone network from it, and that seems to allow having a null password. However neither with a null password nor with an 8 letter password and can I get it to connect to the ASUS athn0 I think I have had athn problems before with the ASUS, and I used to have a spare USB wireless of some sort that was more reliable, but I gave it away, after not having such problems with some other more recent releases (but before 6.7). Wish I could remember what it was. If anyone has a recommendation for a reliable USB wireless stick that I can find on eBay, and plays well with athn, I'd be grateful. Moreover, if anyone can fix the problem before I go to that extreme, I'll send him the shirt off my back... Happens I have about 1,000 OpenBSD T-shirts :-) Austin On Fri, 26 Jun 2020, Kevin Chadwick wrote: > After upgrading via sysupgrade for a few releases, I have had to cold boot to > get dhclient athn0 working on an ar9280 in client mode. > > Since my latest upgrade to a snapshot of Jun 17 kernel #275 with the previous > kernel being from Jun 2nd #237.
