ubuntu 10.04 (64-bit) wireless issues (broadcom STA driver)

hi all,

I'm having some issues with wireless on my laptop using Ubuntu 10.04 (64-bit).

I have installed the driver under System > Administration > Hardware Drivers (Broadcom STA driver). The installation was successful, and it has detected and connected to my wireless network.

The problem is that, while it says it is connected, I can't access anything. I can't even use ping in the terminal.

Anybody else having problems the Broadcom STA driver under Ubuntu 10.04 (64-bit)?

Is it picking up an ip address via dhcp or have you assigned one manually? What's the output of iwconfig and ifconfig -a ?

Here is the output from several commands, including those that you requested. Let me know if you need anything else.

Edit: I don't think it's a DNS problem - I can't even ping the router. When I try, it says connect: Network is unreachable. I've also tried pinging the ip for yahoo and no luck.

A couple of things to note:

iwconfig says encryption key is off, but I have set up an encryption key in the Wireless Security tab.

And I also see:

TX packets:18 errors:21 dropped:0 overruns:0 carrier:0

But I'm not sure what this means.

try this :
sudo apt-get update
sudo apt-get install b43-fwcutter
Use the cable to connect.

For some reason, apt-get didn't work, but I installed the b43-fwcutter package through the Synaptic package manager. I'm still having the same problem. It should also be noted that I don't have an issue when I boot from the 32-bit LiveCD. Maybe there is a problem with the 64-bit driver?
