Help!!! Can not connect to WPA or WEP network...ipw3945

pudgewacl · 2007-07-01 22:00:19

I was hoping someone could please help me with my wifi problem.
I can not connect to a secure wifi network. Although I can connect to a network that does not use encryption.

I am running Duke on a Dell Latitude D620 w/ an intell 3945

Here is some of my history with arch:
I had everything working fine (including wifi connecting to WPA networks via networkmanager)
When the update for ipw3945 came out about a month ago (ipw3945 1.2.1-2), I updated. I had this same problem, so I downgraded to the older version through the file saved in cache. Everything worked well after downgrade.
Yesterday I decided to give KDEmod a try. I preferrred KDE over KDEmod, so I decided to switch back to KDE. I was not sucessfull in the switch back to KDE, so I formatted my HD and reinstalled Arch.
When I reinstalled arch, the updated verision of ipw3945 was installed. Since I no longer have the pacman cache, I do not kow how to downgrade the driver.

I was hoping someone could help me solve this problem. I was hoping there was a fix so I could get ipw3945 1.2.1-2 to work with WPA networks. If I can not due that, I was hoping someone could help me downgrade to a driver that works with WPA.

Thanks,
Matt

Always try to look at the wiki before posting a question; it makes things a bit easier for us. http://wiki.archlinux.org/index.php/Downgrade_packages. If you're still having a problem, I'll help you out.

Thanks for the link smurnjiff. I actually looked at the page a when I learned how to downgrade from my cache....I forgot there was an archive that has some old packages. I will give the one in there a try.

Does anyone have any suggestions/ideas on how to make the most recent verision of ipw3945 (1.2.1-2) work with WPA networks?

Thanks,
Matt

well I am using ipw3945 with wpa2 and vpn. I don't have any problems with the latest driver. The only difference is that I am using either driver compiled from source file or kernel patch to the latest ipw3945. I doubt though that arch package is at fault. Maybe there is something wrong with your wpa settings?

pudgewacl · 2007-07-02 17:13:22

Are there any new settings for the new driver? Or a differnt way to enter the setting maybe?
I have not changed the WPA settings on my laptop of the router. It works perferctly with the old driver. Then when I update to the new driver (using the exact same settings) I am not able to connect to my WPA network. Just to make sure that I had the correct password, i tired to enter it more than 20 times, but I could never get connected.
To test to see wether it was just and issue with WPA, I switched my network to WEP....I still can not connect. I also tested it on a my network with no encyption and it connects without a problem.

Any other suggestions?

Im having similiar problems with ipw3945 and networkmanager. Cannot rollback since this is new installation on this laptop. When I start my laptop networkmanager keeps asking for password for my home wlan forever. But after I do 1-2 times

/etc/rd.d/ipw3945d restart
/etc/rc.d/networkmanager restart

It suddenly connects to my wlan without any trouble.

you can roll back to whatever version you want:

Hi!

I have a ipw3945 too and it's working fine with my WPA network at home...And I'm also using ipw3945 1.2.1-2

I'm not using networkmanager, I'm just using wpa_supplicant and network-profiles...Something like this:

my wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
#fast_reauth=1

network={
       ssid="*******" //replace * for your ssid name
       scan_ssid=1
       psk="**********"  //replace * for your key
       key_mgmt=WPA-PSK
       proto=WPA
       pairwise=TKIP
       group=TKIP
       priority=9
}

and then I set up a new profile, by creating a new file in /etc/network-profiles/

#
# Network Profile
#

DESCRIPTION="Home Wireless"

# Network Settings
INTERFACE=eth2
HOSTNAME=freestailo

# Interface Settings (use IFOPTS="dhcp" for DHCP)
IFOTS="dhcp"

# Wireless Settings (optional)
ESSID=Dragon

IWOPTS="mode managed essid $ESSID"

USEWPA="yes"           # start wpa_supplicant with the profile
WPAOPTS="-D wext"             # use "" for normal operation or specify additional

Then, I edited rc.conf:

I removed all interfaces EXCEPT lo from INTERFACES:

INTERFACES=(lo)

and added this:

NET_PROFILES=(MENU)

Now when I want to connect to some net work, I simply run the following command from a terminal:

net-cfg --menu

this will present a menu, from which I just need to select the desired profile...in this case "Home Wireless".

Sometimes I need to do a dhcpcd eth2 too...

Hope this helps!

Just wanted to add a "me too" to this thread. My 3945 card was working perfectly up until about a week ago, since then I just keep getting the password prompt. Nothing else has changed.

So far, I've tried:

* Clearing the password from my Seahorse keyring
* Rearranging the daemons and modules in /etc/rc.conf
* Reinstalling ipw3945
* Staring off into space thinking about the things I should *really* be doing

I haven't tried downgrading yet... I'll see if that does the trick and post the result.

thayer · 2007-07-06 05:18:45

Yep, that fixed it... I simply rolled back the ipw3945 v1.2.0-6 module package found here:

http://phraktured.net/archmirror/extra/ … pkg.tar.gz

with this:

# pacman -U ipw3945-1.2.0-6.pkg.tar.gz

To test without restarting:

# /etc/rc.d/networkmanager stop
# /etc/rc.d/ipw3945d stop
# rmmod ipw3945
# modprobe ipw3945
# /etc/rc.d/ipw3945d start
# /etc/rc.d/networkmanager start

My ipw3945 works perfectly with both 1.2.0 and 1.2.1. I am not using networkmanager though, but wpa_supplicant. It connects fine to several WPA, WPA2 and unencrypted networks (never tried WEP though).

thayer · 2007-07-06 06:12:54

Hrmmm, then perhaps it does have something to do with networkmanager, since that's what I'm running (via a WPA-TKIP auth) under GNOME. If I get the time tomorrow, I'll confirm whether the newest module works on my system when used with the wpa_supplicant.

Same problem here: I just got a Dell e1405/640m and (probably) I directly used the new driver (1.2.1)
2 days later I changed from 'network' init script to networkmanager and it didn't worked.

Now that I read here, I made NetworkManager working by downgrading the driver to the 1.2.0 version.

Therefore, only this combination didn't worked: networkmanager + new (1.2.1) driver

(Oh, I'm using WPA supplicant too)

ipw3945 work only with 1.2.0 for me not with 1.2.1
plain netcfg no networkmanager

somedrew · 2007-07-12 03:04:40

ipw3945 1.2.1 working here using wifi-radar and wpa_supplicant (1.2.0 had a weird issue sometimes when booting with the kill switch on).
Networkmanager has always been flaky for me connecting to secured networks.
