Won't connect to wireless? [Solved]

Postby temiller » Tue Feb 23, 2010 19:35

I just installed 5.1KDE, and I have a Netgear W111v3 wireless adapter. The adapter will recognize the wireless, and it will see my router, but when I go to connect, it will say "activating" then I'll have to re-type in my password. I've searched, but not really sure of what to search for this problem. Any ideas on why its not working?

Is your WiFi network WEP-encrypted or WPA-encrypted? If it's WPA-encrypted, I know that you wrote that your PC sees your router but is the router configured to not broadcast the SSID?

If it's a WPA-encrypted network with the SSID hidden by the router, uncloak the SSID in the router and try to connect. Then hide it again and try.

Have you tried unencrypting your network and connecting to an unencrypted network?

If it's not hidden and/or not a WPA-encrypted network, try the following as root user in a Konsole window and post the Konsole output in this thread:

Code: Select all
iwconfig

From that you should see your WiFi card's device name, which will probably be wlan0. If it is, try the following command:

Code: Select all
iwlist wlan0 scan

You might have to try the above command a couple of times to get a result.

To show you the sort of thing to expect, below is the output of the above two commands on my laptop in the hotel in which I'm currently staying:

Code: Select all
# iwconfig

eth0      no wireless extensions.

The easiest way to fix this problem is to install nm-applet. There seems to be something wrong with the KDE plasma network manager. I've never been able to connect to a wireless network with it. I just did a fresh Sabayon 5.1 KDE install on my wife's laptop, and ran into the same problem: my card could see other networks, but wouldn't connect. I hooked up to a wired connection, downloaded nm-applet and it's deps, and bingo! No problem since! BTW, don't let anyone tell you that wicd is a good alternative...never been able to connect with it either! Good luck!

Curious, because it works perfectly for me. The only thing I can think of is that its performance is a function of the hardware it's running on, but that doesn't seem logical either.

Same for me (well I did get it to connect once, but it was flaky). But some people who can't get NetworkManager to work do have success with Wicd. I have no clue why the opposite is true for some people. Networking under Linux is sometimes confusing, to say the least.

I was able to get it working. I just slept on it then got up and tried and it magically worked. I'm very new to linux so i'm learning as i go basically.
