no wireless internet

[WarrenKarl]

Hi,

I love Ubuntu. I installed Jaunty from the CD that I downloaded
and my wireless internet does not work. This is strange because I had no problem with it on Intrepid.

I did a sudo lshw - C network and this is what I got:
*-network
description: Network controller
product: BCM4328 802.11a/b/g/n
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:03:00.0
version: 03
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list
configuration: driver=b43-pci-bridge latency=0 module=ssb
*-network DISABLED
description: Ethernet interface
physical id: 1
logical name: pan0
serial: ba:91:b0:79:10:b0
capabilities: ethernet physical
configuration: broadcast=yes driver=bridge driverversion=2.3 firmware=N/A link=yes multicast=yes

I don't know what any of this means, but it is clear that the network is DISABLED.

Please help. I am going through Ubuntu withdrawl.

Hi,
It's me again. I have failed to get the wireless internet working.
Here is some more information. I have a Broadcom wireless card in my HP
laptop. The number is BCM4328. I took my laptop to a wire and downloaded
b43-fwcutter and got the appropriate firmware. Now when I go to System>Administration>Hardware Drivers, it tells me that I have the
Broadcom driver, that it has been activated, but that it is not used
(whatever that means).

When I do a iwconfig I get
l0 no wireless extensions
etho no wireless extensions
pan0 no wireless extensions

I have tried a sudo /etc/init.d/networking restart but nothing
happened.

Does anyone have any further ideas for me?
Please.

P.S.

Ubuntu does not see the router. I have a network icon that shows bars
with no signal and an x. If I left click on it all the options are greyed
out. If I right click on it, I can edit wireless network connections, but
there are no wireless connections.

Should I try to manual add a wireless connection? If so, do I need to
put in my MAC address and other details?

The router worked perfectly with Intrepid and works perfectly when wired
to the computer.

I hope someone knows.

I don't have any further ideas, sorry.

But here's a bump for your thread. Maybe someone smarter than me will see it and jump in. :KS

Similar problem, posted in another thread. Problem started with Jaunty and was carried on when downgraded to interpid.

Need to see full output of


ifconfig

and contents of

/etc/network/interfaces

Don't wanna take over this thread, so I'm posting output in my thread.
