Wifi won't scan

[dodecar]

As a new user,I must say I love Pclinuxos,however I find the wifi a problem as it usually will only scan after I've been on Windows(which I'm absolutely sick of). I can't understand it. All I can say is that sometimes it scans and sometimes it doesn't,it won't always connect either when it does. Does anyone have an idea what's going on? Thanks.

Thanks AS .Such prompt help. I am indeed lucky to have found this fabulous system! I have an Acer 5600 which has a network adapter (Intel(r) Pro Wireless 3945ABG).I'll have a look at your link. Thanks again.

You are indeed lucky, this is the same wireless adapter that I use, and indeed it is somewhat unstable while using kernel-2.6.38.8.
open a terminal and edit the file /etc/modprobe.conf, add the following lines:

options iwl3945 fw_restart3945=1
options mac80211 ieee80211_default_rc_algo=pid

reboot your system, and report back.

My editing skills are next to zero but I  read up on it and tried . I've no idea if I did it right but it's made no difference.

do you expect we can have a better view about your config files ?

dodecar,

Open a terminal. Enter the following line in the terminal.

cat /etc/modprobe.conf

Copy all contents of the terminal window after entering the command. Paste the contents to your next post.

[don@localhost ~]$ cat /etc/modprobe.conf
install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true
install ide-controller /sbin/modprobe ide_generic; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true

Don't know if it helps AS but I am able to scan and connect Pclos to wifi(I am now)after previously having been connected on windows. Thanks for your patience and tolerance of my ignorance.

 [don@localhost ~]$
[don@localhost ~]$ cat /etc/modprobe.conf
install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true
install ide-controller /sbin/modprobe ide_generic; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true
alias wlan0 iwl3945
alias eth0 8139too

alias pci:v00008086d00004222sv00008086sd00001001bc02sc80i00 iwl3945
[don@localhost ~]$
[don@localhost ~]$ cat /etc/modprobe.conf

you need to change the above as follow:

install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true
install ide-controller /sbin/modprobe ide_generic; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true
alias wlan0 iwl3945
alias eth0 8139too
options iwl3945 fw_restart3945=1
options mac80211 ieee80211_default_rc_algo=pid
alias sound-slot-0 snd_hda_intel
options snd-ac97-codec power_save=1
alias pci:v00008086d00004222sv00008086sd00001001bc02sc80i00 iwl3945

How to edit the file: you need to open a terminal type su, type in the root password when requested, if OK you will get a prompt like this:  '#'.
then type:

Code: [Select]

kwrite /etc/modprobe.conf
copy and paste the two lines highlighted in red into that file, save, reboot.
