difference between ipw3945 and iwl3945 ??

perbh · 2008-09-29 22:29:46

My 'latest' (ie uptodate) arch loads them both ...
modprobe.conf tells me that "alias wlan0 ndiswrapper"
netcfg (and yes, I have made an entry with just the basics: essid, channel, security=wep, key and ip=dhcp) times out when run manually saying "network unreachable'
iwlist actually gives me the right a/p, men the sucker doesn't want to connect :-(
actually - using NETWORKS=(menu) does nothing at boot - and dialog _is_ installed!

Anmy help would be greatfully accepted!

To answer the subject, ipw is out dated. Blacklist it.

To answer your post, check to see if any of this is related to the above, if not, you've got a netcfg question. Lots has changed with the latest netcfg so if you've not looked at it in a while you may want to revisit the wiki.

hmmm - that link didn't work at all (page not found!)

I have two laptops - one is a thinkpad t61 with an Intel 4965 adapter and the other is a dell precision with a 3945ABG adapter.
The thinkpad uses the iwl4965-module and 'alias wlan0=ndiswrapper' and works just dandy.
The dell, if I load iwl3945 (also has 'alias wlan0=ndiswrapper') does not even have a wlan0 device, so any attempt to use iwlist et al is a failure. If I select ipw3945, I get a response (of sorts) and 'iwlist' does find the access point though it will not connect in any way.

I'm at my wits end here - haven't checked out the wiki yet but I'm about to ...

The only link in my post is in my signiture and is not related. If you modprobe -r ipw3945 && modprobe iwl3945, then do iwconfig do you see a wireless interface?

oooops *blushing* I stand corrected - I thought you were pointing me to something!

the answer is NO - I have no wlan0 if I only load iwl3945.

I have read the wiki - and I have tried either iwl3965 or ipw3945 - none of them give me wlan0 though at some stage (when I wrote my first posting) i actually had a wlan0 just couldn't connect :-(

Now I have zilch!

Silly question, have you installed the iwlwifi-3945-ucode package?

perbh · 2008-09-30 02:17:45

not such a silly question - but yes I have.

here's the dmesg-part (dmesg | grep 3945):
iwl3945: Intel (R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks
iwl3945: Copyright ...
iwl3945: Detected Intel Wireless WiFi Link 3945ABG
iwl3945: Tunable channels: 11 802.11bg, 13 802.11a channels
phy0: Selected rate control algorithm 'iwl-3945-rs'

Interesting. I've got the same output, however the very next line says:

firmware: requesting iwlwifi-3945-1.ucode

Unfortunately this is about as far as I can help, maybe someone else can pick up from here.

actually, I now _have_ a wlan (after running 'netcfg home-wlan', but 'dmesg|grep wlan' gives:
ADDRCONF(NETDEV_UP): wlan0: link is not ready

which is bs because I'm writing this on the other laptop (iwl4965) which works ok, but ... I do have to run netcfg {profile} twice to get it to work - the first invocation always fails ...

the home-wlan is:
CONNECTION="wireless"
INTERFACE="wlan0"
SCAN="yes"
SECURITY="wep"
ESSID="my-essid"
CHANNEL="6"
KEY="XXXXXXXXXX"
IP="dhcp"

perbh · 2008-09-30 02:29:19

Oh crap!!
I had misspelled my ESSID - darn it!!
Now it works fine.
Awfully sorry for the troubles :-(
(and thank you so much for trying to help)

Sweet. Glad it's working. You also may want to check into the QUIRKS array in the latest netcfg. May resolve your problems with running the profile twice.
