help - no network connection! neither wired nor wifi

Hi All,

Could somebody please help me?
Got my Acer Aspire One 4 days ago. It's the AA1 A110-AaGb, 16Gb SSD, 1Gb Ram version.
I immediately installed Ubuntu on there (the netbook remix, UNR Jaunty Daily Image) and got everything to work. A day later I installed Sickboy's kernel ( linux-image-2.6.28sickboy-kuki_0.4_i386.deb), and life was great!
But today suddenly my netbook could not create a new connection, not wired and not via wifi (both were working fine the days before, eth0 out-of-the-box and wifi after some tweaking).
So I tried undo-ing all the changes I made that day: nothing
back to the previous kernel: nothing
re-installing the sickboy kernel: nothing
entire reinstall of the UNR Ubuntu 9.04: nothing
again install of sickboy kernel: nothing
shutting down, removing power cord removing battery and waiting for give minutes, then booting: not... well you get the idea.

I'm quite the noob, but from what I gather everything seems ok
dmesg shows something strange on wifi (dmesg | grep wlan):

[ 21.881721] wlan0: direct probe to AP 00:1c:df:8c:0c:6d try 1

reason=3???

also, networkmanager shows all the connections (including wifi) and the wifi led is blinking and stuff, just no connection is established.

please does someone know what to do?

have you tried to check your router first?

 

yep, I even removed the router altogether. No deal.
I can see my wireless connection and the eth0 connection in the network manager app, but clicking it just shows a disconnected message after some seconds.

 

The default kernel in 9.04 NR is already good in my opinion. I would suggest that you try to reinstall , there have been tonnes of updates during the beta release.

 

It seems the problem was in my internet connection all along. This morning my desktop (which had working internet the day before) couldn't connect anymore aswell. First guess is my internet connection got shut down for some reason (a virus seems unlikely, but perhaps someone managed to send spam via my computer. Anyone any ideas on how I can check this?)
curiously my Internet connection kept up yesterday on the desktop until I rebooted. My Internet connection on the AA1 also failed afetr a reboot, yet there is also no Internet when I boot my desktop to Windows.
My neighbour was kind enough to lend me his Internet connection, so I am typing this from my AA1 with a working Internet connection. Mind boggeling!

Anyway Thanks for your fast replys!
