[aklug] Re: Acer Aspire One D250 Wireless problems

Not just newer kernels, but newer firmware builds as well.

https://launchpad.net/ubuntu/${DISTRO}/+package/linux-firmware<https://launchpad.net/ubuntu/$%7bDISTRO%7d/+package/linux-firmware>

where distro could be from trusty to vivid, depending on how far up the chain you want to play.

Or.. if you hate life, you could use my stupid scripts that I wrote to do this for me.

https://github.com/akhepcat/system-update

It's... not pretty. but it mostly works most of the time.

I've just pushed these to github, so there's not a lot of information, though they do have built-in "help"

You might consider a much newer kernel from: http://kernel.ubuntu.com/~kernel-ppa/mainline/

I've got a "rescue netbook" here bequeathed by one of my 'kids' for

my wife's use when she travels.

When my daughter had it she used windows 7 and told me that the

wireless was entirely reliable.

I put lubunt 41.04 on it and had problems with the wireless

connection being unreliable - one time I might have a wireless

connection and see wlan0 in ifconfig and the next it would be gone,

wlan0 would be gone from ifconfig.

In such a case I would plug in ethernet, get a connection and then

when I rebooted the netbook, wlan0 would be visible and so would

wireless connections.

I then reinstalled with xubuntu 12.04. As with lubuntu, xubuntu

found wireless without any problem and connect successfully. I

immediately ran the script available here :

http://dl.dropbox.com/u/57264241/wireless_script

and stored the output.

You can see that output at

http://akwebsoft.com/clients/transfer/wireless-info_initial_install.txt

Later, I found the same problem as in lubuntu, wireless connections

were not visible in Network Manager wlan0 was absent from ifconfig.

I then ran wireless_script again and saved the output at

http://akwebsoft.com/clients/transfer/wireless-info_after_reboot.txt

I have also syslog excerpts from that session and those excerpts

I haven't had any luck from posting to ubuntu forums and

askubuntu.com is not accepting my question :(

I did find the following reference to the AR542x Wireless Network

Adapter at the following site :

http://ubuntuforums.org/showthread.php?t=2160177

And preformed the remedy suggested at the reply which you can find

by doings a search on "try to deactivate".

I've done a couple of reboots and at first, I was getting wireless

and it is gone again. This is very frustrating as it will drive my

wife nuts!

I know that there are folks on this list who can analyze the data

and probably suggest the solution and I hope that one of your will

have the time.

thanks

tim
