Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard. And I figure this might help a bit

I have tried installing WICD and it didn't fix the problem. Any help would be greatly appreciated. This problem is greatly limiting what I can do with my computer.

I see. I have also had wifi issues with the realtek rtl8188ce : driver rtl8192ce. I tried disabling wirelessN on my router, The only solution that has worked so far today is turning off the wireless power management.

1.gksu gedit /etc/pm/power.d/wireless



/sbin/iwconfig wlan0 power off

  1. sudo chmod +x /etc/pm/power.d/wireless

You could try this:

Type the following in the command line

sudo gedit /etc/nsswitch.conf

This will open the nsswitch.conf file in the text editor. Then simply change the following line

hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4

to the below line and save the file.

hosts: files dns

If this does not work you could try 1. installing the linux driver for your wifi, 2. using ndiswrapper

This is for the wrong version of ubuntu and doesn't even reference the OPs wireless hardware! – Jorge Castro May 1 '12 at 0:05
this works in 12.04 – mac1133 May 1 '12 at 3:18
Unfortunately it didn't solve the problem, though I am looking into NDISwrapper still, and as far as I know there isn't a linux specific driver for this adapter. – William Berkenkamp May 1 '12 at 12:32
