WiFI trouble - possibly through update

hey folks,

a couple weeks ago i installed slitaz rolling on a friends laptop. all worked well, apart from connecting to his wifi network. i dont use wifi at home that much, but when i tried it recently i got the same error as my friend did (message below).

i usually connect via

/etc/init.d/network.sh restart /path/to/configFile

upon trying it now (i usually update packages when there are updates) i get the following:

root@slitaz:/home/tux # /etc/init.d/network.sh restart /home/tux/.network/WiFiKenny

Loading network settings from /home/tux/.network/WiFiKenny

Re: WiFI trouble - possibly through update

There have been many changes to /etc/init.d/network.sh and /etc/network.conf

http://hg.slitaz.org/slitaz-boot-scripts/rev/6c2d6362887d

http://hg.slitaz.org/slitaz-boot-scripts/rev/f3e7c1cc6aef

http://hg.slitaz.org/slitaz-boot-scripts/rev/28a9c8b64212

http://hg.slitaz.org/slitaz-boot-scripts/file/a8aa6b77a7ed/usr/share/slitaz/network.conf_migration

The last one adds a script that renames your existing /etc/network.conf and creates a new version of network.conf in a different format.

There is a bug report about wifi problems: http://bugs.slitaz.org/?id=147

I run custom boot scripts and have slitaz-boot-scripts blocked for over 3 months to prevent overwrite on updates.

You can try rolling back the update of slitaz-boot-scripts that owns /etc/init.d/network.sh and /etc/network.conf

Rename /etc/network.conf to /etc/network.conf.old before the rollback.

Reconfigure /etc/network.conf installed after the rollback.

On your system check /var/log/tazpkg.log to see if you updated slitaz-boot-scripts prior to the last update to find the version that worked.

If you never updated then boot your install iso:

[c]tazpkg search slitaz-boot-scripts[/c]

Outputs slitaz-boot-scripts version you started with.

Attached is every version of slitaz-boot-scripts going back to 5.6.1 that was in slitaz-5.0-rc2

[c]tazpkg install slitaz-boot-scripts-<version>.tazpkg --forced[/c]

After you find the version that works.

[c]tazpkg block slitaz-boot-scripts[/c]

Re: WiFI trouble - possibly through update

Hi K3nn3th,

rfkill: WLAN hard blocked

Quick answer: very possible, this error means WLAN card was switched off manually by your friend.

It may be slider without fixation (as for my netbook) of Fn + F3 keys combination (as for my son's notebook), or something similar. Switch WLAN card on, wait few seconds and try to start Wi-Fi connection again.

Long answer: hardware switch may not help. Some WLAN cards supporting software Rfkill. You can install package (I can't recall the name) and manage Rfkill in the command line. Please, search forum for "rfkill" — mojo answered few times.
