how would you troubleshoot your wifi?

[Miles Keaton]

I'm an intermediate OpenBSD user since 2001, but never needed my wifi
before.

When I connect to an open (no password) nwid it works fine, but when I try
to connect to one with a WPA2 password, it just fails with no clues I can
see. I'm using the correct password - (works fine on my phone, etc).

Any tips on how else you would troubleshoot this? Thiis is all I've got:

# ifconfig iwm0 scan
nwid SINGTEL-1D14 chan 2 bssid 00:25:75:af:1d:15 97% 54M
privacy,short_slottime,wpa2

# cat /etc/hostname.iwm0
nwid SINGTEL-1D14
wpakey "00114764294" # (NOTE: tried it with & without quotes. no help)
dhcp

# dmesg | grep iwm0
iwm0 at pci2 dev 0 function 0 "Intel Dual Band Wireless AC 7260" rev 0x83,
msi
iwm0: hw rev 0x140, fw ver 25.228 (API ver 9), address 5b:51:4f:a1:16:d9
iwm0: fatal firmware error

I'd believe the "fatal firmware error" except, like I said above, this same
iwm0 wifi connected fine yesterday to an open (no password) nwid.

Thank you.

Do not trim your dmesg or config file to whatever you think is
necessary to show.
The OpenBSD version is a critical information for any serious
troubleshooting operation.

iwm0 wifi connected fine yesterday to an open (no password) nwid.

ifconfig iwm0 debug (or debug in your hostname.iwm0 file for a more permanent presence)
should produce more verbose reporting, at least. And of course, a full dmesg
along with ifconfig -a output would likely be useful.

Running tcpdump to capture whatever passes through the interface while you're
trying to connect is another main source of information about what fail and how,
of course.

Some access points are just plain weird - in some cases I've had to play with
of all things mtu sizes (setting them to various values lower than the 1500
byte default) in order to successfully connect. Any quirks like those will
turn up as the hints tcpdump will show you.

Hi,

I think you miss a word, "wpa", just before the key declaration:

wpa wpakey 00114764294

Did you update your firmware?, i.e.

# fw_update

iwm0: fatal firmware error

You got some answers already but they were all misleading.
I believe I've already fixed this bug. Please verify my assumption by
upgrading to -current now and letting me know if the problem persists.
(Run fw_update iwm before upgrading or iwm won't work during the upgrade!)

I'm also observing this error and I'm experiencing massive problems with
regard to wireless performance on current (compared to 5.9 at some
point) - unfortunately, I've been observing these for some time now. My
guess would be that its related to iwm(4) but it could potentially also
be related to the ral(4) side which runs in 802.11g hostap mode on
current. I didn't have any time in order to look into this deeper yet --
I also made some changes with regard to the position of my access point
but this (at least now) seems to be completely unrelated to the observed
problems.

Sorry for being of no help atm with regard to reporting observed
problems with current in a timely manner.

Best regards
Andreas

the observed performance problems are still there.

You got some answers already but they were all misleading.
I believe I've already fixed this bug. Please verify my assumption by
upgrading to -current now and letting me know if the problem persists.
(Run fw_update iwm before upgrading or iwm won't work during the upgrade!)
