Thanks again!!

I've run md5sum and get:

100% 0d31753df93abc28c5544e7136097fa6.

I can't run ipconfig when it is connected as it drops before I get a chance. This is it before it drops:

Code: Select all

Basically, if I try and connect I get the following messages within the space of a minute (where S-H is my network):

Code: Select all

SH -1% WPA Channel 
Automatically connect to network

Connecting
S-H: Flushing the routing table....
S-H: Putting interface up....
S-H: Generating WPA configuration file.....

S-H: Obtaining IP address.....
Connected to S-H" Nickname:<WIFI@REALTEK> at 0% IP(192.168....
S-H: Done connecting....
S-H: Not connected
The last two lines seem to happen almost instantaneously!

Ok. Ruled out that unknown. I've been looking at old 2014 and 2013 posts/blogs about patching the firmware. What throws me is this is 2015 and I know Debian is slow. But not that slow?

Maybe some other member can help us on this conundrum?

You know? Studying this issue. Wondering if going with a Vanilla Debian Kernel 3.18 on up or a liqourix kernel 3.18 on up would fix this dropping out issue.
Since you are on a custom 4.0.5 kernel and maybe some configure issue is present in it with this driver and firmware.

I need to boot my Netbook and look at my Sid kernel sources list and post them back here I think.

In my / etc/apt/sources.ist/various.list I have enabled

Code: Select all

deb http://liquorix.net/debian/ sid main
in my / etc/apt/sources.list.d/siduction.list I have enabled

Code: Select all

 deb http://packages.siduction.org/base/ unstable main contrib non-free
if you do not have a various.list or siduction.list text file in / etc/apt. Make those files and put in there the repos I have posted. Save and exit. You can do that via antixcc>system>edit config files. Just pick new file for / etc/apt and go for it.

After saving.

Code: Select all

sudo apt-get update
let it finish. Then go in synaptic package and search for kernels. I'd start at 3.19 and reboot into 3.19 and test if drops still occur.

I am familiar with kernel changes on my gear when having weird problems myself.
I changed the kernel on this netbook because of a screen dimming issue with newer kernels than I am running now in AntiX 15. So I downgraded the kernel and uninstalled the one that came with AntiX 15 to fix my issue

Code: Select all

$ uname -r
3.16.0-4-686-pae
That kernel was the sweet spot for my screen dimming issue and still gave me touch screen functions on this netbook.
