wlan0 problem - not coming "UP"

#1 Post by duffmckagan »

Hi,

Edit: Slacko Puppy 5.5 Kernel 3.2.33 - 4g

Till yesterday everything was working fine and suddenly my Wi-Fi on the netbook stopped working.

I haven't applied any updates or changed any software etc on this netbook. However, there was an improper shutdown which may have caused the problem. Still, I have no clue what changed that my wlan0 Wifi network interface won't come up.

Output of

Code: Select all

dmesg | grep -i eth

Code: Select all

[ 0.224036] ACPI Error: Method parse/execution failed [\_SB_.PCI0._OSC]

This is when I am connected to the network by a wired connection through wlan0.

Also, output of

Code: Select all

dmesg | grep -i wlan

Code: Select all

5.100.82.112
Puppy is running on the hard drive as the only OS. Don't want to re-install either. Thanks.

Does your netbook have a physical switch on the case that enables WIFI? Maybe it is now in the OFF state.

a. Whenever there is an improper shutdown when running a Puppy...
I would ALWAYS make sure that prior to running another session of that Puppy, I would have a scan&fix run on the [filesystem in the] pupsave file [if one is in use], and also the partition-file-system [PFS] of the partition holding the pupsave [or full install].
I do this because I believe that an improper power-off is likely to corrupt the PFS.
An ext3 or ext4 filesystem is more likely to be fully recovered than an ext2.

b. I normally do this by entering the following command during the 5-sec pause during the Puppy startup:
puppy pfix=fsck
