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 "/etc/pm/config.d/00sleep_modules": SUSPEND_MODULES="ath9k" None of these have fixed the problem. Dmesg | tail reports this: <a href="http://pastebin.com/4aSJgVMp">http://pastebin.com/4aSJgVMp</a> 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?
