Hi,
Seeing that iwl3945 is now merged, I decided to switch my x60 to use
that instead of ipw3945. That would leave me with zero kernel
dependencies.
Unfortunately it doesn't work. Loading the module reveals the device:
iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for
Linux, 1.1.17ks
iwl3945: Copyright(c) 2003-2007 Intel Corporation
ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 21
PCI: Setting latency timer of device 0000:03:00.0 to 64
iwl3945: Detected Intel PRO/Wireless 3945ABG Network Connection
iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels
phy0: Selected rate control algorithm 'iwl-3945-rs'
# iwconfig wlan0
wlan0 IEEE 802.11g ESSID:"xxxxxxxxxxxxxx"
Mode:Managed Channel:0 Access Point: Not-Associated
Tx-Power=0 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Encryption key:XXXX-XXXX-XX
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
and iwconfig sees it, essid/enc settings are fine, but I don't get a
link.
Same issue here, try iwlist wlan0 scan first and then it should work.
Huh indeed, now it links fine! Thanks for the hint. Would be nice to
have fixed, though :-)
Odd, doesn't the driver need to do a scan _anyway_ to find the right
BSSID to associate with if the cached scan results are more than a few
seconds old? Can you run '/sbin/iwevent' before trying a fresh
association, try to associate, ensure that it has failed, and report the
output?
If you don't get something like:
10:17:05.117937 eth1 Scan request completed
shown there, then there's likely a bug in the driver because it's either
(a) not scanning before trying to associate, or (b) not sending out scan
completion events after it's done a scan.
Indeed, there is now Scan request completed before I run the iwlist
scan. iwevent output:
Hmm, the output below doesn't show the scan request completed, right?
Waiting for Wireless Events from interfaces...
16:20:27.453588 wlan0 Set Mode:Managed
16:20:27.462104 wlan0 Set Encryption key:off
16:20:27.463940 wlan0 Set Encryption key:****-****-** Security mode:open
16:20:27.466535 wlan0 Set ESSID:"kjellbergaxboe"
waiting, nothing else happens. Then run iwlist scan from another
terminal.
16:20:53.892549 wlan0 Scan request completed
So you only get this when you manually scan right after setting the ssid
and key?
If you look at the time stamp, I ran the iwlist scan about 26 seconds
after loading the module. When the module is loaded, the networking
script sets the essid and encryption key.
So yes, I only get that 'Scan request completed' line after running
iwlist scan manually.
Don't know whether this is related, but I was having all kinds of
trouble getting associated,
iwlist eth1 scan would report no scan results, I then switched to
loading the kernel module with
the option that tells iwl3945 to do software scanning and it works
everytime now.
