IPW3945 wireless card detects network, but does not connect

Asked by Beth

I recently installed Ubuntu 7.04 and it all went great. I have used Ubuntu before, but older versions.

I have an MSI M662 laptop and need to get wireless internet working. I have an Intel IPW3945 wireless card - it is supposed to work right out of the box.

My computer detects the wireless network -- when I click the network button in the top right, it shows the wireless network and high connection strength.

When I try to connect, it will not connect. It tries but fails every time. I am not sure why.

Any ideas? Am I missing something?

Thanks!

Can you provide the output of "iwlist ath0 scanning"

Hey

It says:
"ath0 Interface doesn't support scanning."

Ok, I assumed it was ath0.

If you type 'iwconfig', and take the device that has wireless extensions into the iwlist command, what output do you get?

for example on my system (see below), I would use ath0, but yours may be eth1 or something else.
=================================
dan@silver:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 no wireless extensions.

wifi0 no wireless extensions.

Okay, here's what it's saying:

$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

Try prepending "sudo " to those commands

as root, those commands give the same results.

How did you solve this? The thread ends without a solution and I am having the same problem.

Thanks!

I actually did not manage to solve this... I still can't connect. Maybe we could solve it together...

hey!

So I'm a student and my exams recently ended, and I have time to fix this again.

I have noticed that my wireless card does not connect at my school. It finds the wireless signal, tries to connect but fails.

I was at a hotel a few weeks ago, and it did manage to connect to that wireless signal, however, failed to load the hotel's website where you're required to 'agree' to things before it moves forward.

I don't think it's a problem with the drivers... could there be some sort of firewall issue or security flaw?

Please help!
Beth
