Unable to establish WiFi connection on MacBook Pro with 10.04

[Jeremy McCoy]

On my [MacBookPro4,1], I have installed the first beta of Ubuntu 10.04 and updated all the packages. When I use the restricted drivers tool to install the correct Broadsuck drivers, I am able to see my WPA2-secured network and attempt to connect to it. However, 90% of the time, it will time out for no explained reason. If you know where I can find some useful log files, I would be glad to send them to you.

Stay sexy,

I have the same problem here with a Macbook pro 5,3.

Connecting to a WPA, WPA2 network it's painful. Sometimes, under certain particular circumstances it connects right away. Most of the time, it just doesn't.

For example, If I enter in "recovery mode with network", then login and "startx", it suddenly works.

After a new installation, the problem is less intense. Under certain unknown circumstances I have to do a few tries until it connects, but usually ends up connecting. The major problem now is instability. Network-manager gets disconnected a lot.

It is really annoying. The problem persists, sometimes it takes a lot of tries to connect, sometimes only one. Sometimes it disconnects every few minutes, sometimes stays connected through the night...

I think this is probably a duplicate of 482668. The range of issues is quite broad but the commonalities are there. Problems regarding instabilities of the wireless connections with Macbooks or more generaly, BCM4322.
