Hi, I'm using Ubuntu 10.04
I'm having trouble staying connected to a wifi network as the subject of my
email describes. To give you more detail, I will say that what is happening,
is I will suddenly stop receiving data packages. Network Monitor does NOT
detect that I am disconnected. I haven't been patient enough to see if it
will reconnect on it's own, because simply going up to NM in the top bar and
selected the wireless that I want again does the trick. But I don't want to
continually have to deal with this problem.
Among the things that I have tried after following some of the forum posts
that I have discovered with research are updating the kernel and creating a
file /etc/modprobe.conf and placing the lines
alias wlan0 iwlagn
options iwlagn swcrypto50=1 swcrypto=1
inside. I also placed this short line inside the file I created under
None of these have fixed the problem.
Dmesg | tail reports this:
In particular, this line has drawn my attention: [ 2134.207681] wlan0:
deauthenticating from 30:46:9a:3d:b2:1a by local choice (reason=3)
I am on an Acer 5740-6025 laptop. The wifi card is supposed to be this:
04:00.0 Network controller: Atheros Communications Inc. AR928X Wireless
Network Adapter (PCI-Express) (rev 01)
Does anyone know why this is happening? or what I can do to fix this?
