What's wrong with my wireless connection (Ubuntu Linux Q)?

Asked by DominicX (28762points) June 28th, 2010

So I just downloaded the latest version of Ubuntu Linux and installed it on my old Dell Inspiron E1505. But I can’t seem to get a wireless connection going.

In the upper right corner, there’s a red exclamation mark over the wireless network icon. It just says “Wireless Networks: disconnected”. The wireless network is not showing up and neither are any other ones that usually show up from neighbors.

I clicked “connect to hidden network” and typed in all the correct information, but it won’t connect. It just says “Wireless Networks: disconnected” again when I try to connect.

I also noticed that the WiFi light on my laptop is not lit up.

I’m sure this will become an orphan, but I know there are some Linux geeks on here. Any help? :(

I’m sorry, this is a simple-minded answer, but I have more than once left my wi-fi- switch on my computer off. Are you sure it’s enabled?

Try typing in terminal “iwconfig” see if you can see your wireless device

Also try restarting your network devices with “sudo /etc/init.d/networking restart” see if that will restart anything for you.

The only way to switch it off with this laptop is to enter the setup in the beginning, which I just did. (I thought of that too). I’ve never disabled it before and it was enabled. Didn’t seem to make a difference.

I typed in “iwconfig” and it says “no wireless extensions”.

Perhaps your wireless drivers are not properly installed.

Try going under System->Administration->Hardware Drivers. Check if there are any wireless drivers it may want to install. This also applies to any graphics drivers that need to get installed as well.

Thanks! It works now. :)

I hooked it up to my wired ethernet and there were two wireless drivers that it needed to install and I did and now it connects to the wireless internet. :)
