ipw3945 problem [solved]

Kardell · 2008-03-05 01:12:16

I think after recent updates something goes wrong with my wifi driver. Someone said that the new kernel release contains ipw/iwl3945 modules.
After few hours suddenly I`m getting disconnection.

modprobe -r ipw3945

grind to a halt and ipw deamon is consuming 99% of processor.

Should I switch to iwl driver or do something with ipw module and daemon (uninstall old package)?

Give the iwlwifi method a try. It is (more?) actively developed now so may have fixed your issue.

Using it is as simple as installing iwlwifi-3945-ucode, and in /etc/rc.conf changing ipw3945 to iwl3945 in your MODULES array and removing ipw3945d from you daemons array. Just as simple to revert if you want to.

I did that, but as before iwl driver behave strangely.
KWifiManager and Wifi-Radar were displaying proper connection, gateway was established, but I even couldn`t send pings to my router -

ping: sendmsg: Operation not permitted

???

I simply came back to ipw3945 driver and downgraded my kernel from 3-1 to previous one - 2-1. Now I`m not experiencing any unexpected disconnections.
Downgrade to 1-2 unfortunately caused loss of touchpad control.

Imagine you'd drop all the gui-wifi managers and use cli instead:

hmm what does ifconfig show me?
$ ifconfig <--- aha! ...hmm so lets try iwconfig:
$ iwconfig <--- aha! ...looks promising! let's try scanning for networks!
$ iwlist wlan0 scanning/scan ---> that's it, there it is, that's my network! ... let's configure:
$ iwconfig wlan0 essid "blahESSIDblah" key "123key456" (...) euh... did I use wep-hex, or web-something else, or wpa? (...) let's see then:
$ dhcpcd wlan0
$ ping -c3 www.google.com <--- /me smiles

Where does it go wrong, using iwlwifi?

ps. sorry

Kardell · 2008-03-06 00:24:02

Haha! Sure
I was playing with wifi commands in terminal as well or simply I had to, otherwise never connect with some repos.

After kernel downgrade iwlwifi works!
After few hours ipw3945 driver failed again, so I think it should be downgraded below 2.6.24, but who cares.
