Ah, this worked. Switched the AP security mode from "WPA2/WPA Personal mixed" to
"WPA2 Personal" and now I can associate and get DHCP lease from the AP. 

Seems the wpa1 support is needed when the AP is supporting both in order to
negotiate which mode to support.

- does it associate or not? (Paste output from just "ifconfig iwn0")

- what shows up in logs if you do "ifconfig iwn0 debug" and then
"ifconfig iwn0 scan" ?

- it might be useful to capture some beacons:

 tcpdump -n -s 4096 -y IEEE802_11_RADIO -v type mgt subtype beacon -i iwn0

Try disabling WPA1 on your AP. In your AP's configuration,
look for config items such as "WPA2", "CCMP", "AES" and enable them.
Disable anything labeled "WPA1" and/or "TKIP".

Not that this is much help, but the reason I asked is I have (had) an AP (made
by WD) with a similar problem. Worked without problems with 6.0, then sometime
after that the new 802.11n code made it disappear. Can't associate, can't see
the AP at all in ifconfig scan. The problem is unresolved (I ended up
replacing the AP). There is a particular kind of packet which seems to be
"invisible". But I'm out of my depth. Nobody else had seen this, but you
appear to be the lucky second victim.

Actually, did quick test and seems that I can get link and ip when booting 6.0
bsd.rd.

Haven't tested the older release, as I said just got the new router.
I can try later with older bsd.rd to see if it works with it.

But scan results see the 2.4Ghz network but not the 5Ghz network:

$ doas ifconfig iwn0 scan | grep MyNet
nwid MyNet chan 11 bssid xx:xx:xx:xx:xx:xx -21dBm HT-MCS23

Could try disabling some of the fancier wifi features / variants on
the WAP to see if it then starts working better - there's sometimes
a workaround or clue in the outcome of that.

Does it work with 6.0? Does the network appear in scan?

Wireless not working with Linksys

[Timo Myyrä]

Hi,

I just got Linksys 1900ACS wireless router and it works great, except with
OpenBSD. I've got Thinkpad T430s running -current and I can't get DHCP lease 
from the new
router. 
I noticed lines: "dhclient[22294]: fatal in iwn0: yielding responsibility" in
messages file which might be relating to this.

Any ideas what could be the problem and how to begin debugging this further?

Timo
