11.04 wireless issues

[vampiregoth28]

The network icon comes up, but there is not a wireless section at all, just wired and VPN connections. I'm using a Dell Inspiron 1420, with a Broadcom wireless adapter.

Before updating to 11.04, the wireless worked, but only after installing other packages. I've looked at similar issues that other's have been having, but I haven't been able to fix it.

Thanks for any help that anyone can give me.

have you installed the broadcom sta drive? go to Applications>system>Additional Drivers. and follow instructions.

Sorry, I forgot to put that in my first post.

Yes I have installed the STA drive. It comes up on the drivers list, but still no wireless

I had the same problems... this is what I did:
- I removed the STA driver from Additional Drivers
- I opened synaptic and installed b43-fwcutter then firmware-b43-installer
- Reboot

Now it works.

Still doesn't work for me here

I have remove all STA from the Synaptic (broadcom-sta-* and bcmwl-kernel-source), installed b43-fwcutter and firmware-b43-installer, reboot, and still nothing happened.

The confusing bit is, when I run 'modprobe -l | grep b43' the result is:

alvonsius@cupuwatu:~$ modprobe -l | grep b43
kernel/drivers/net/wireless/b43/b43.ko
kernel/drivers/net/wireless/b43legacy/b43legacy.ko

So it seems that the driver is loaded ... but nothing happened

FYI, I'm using Lenovo G400, lspci said that:

03:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

Any hint would be helpful, before I go back to Maverick T_T

Solved for me now!!!

After installing the b43 driver, some of us might have to remove the b43 from blacklist. And I found that it was blacklisted on:

/etc/modprobe.d/broadcom-sta-common.conf

I fired up nano, and edit the lines into:

# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
blacklist b44
#blacklist b43legacy
#blacklist b43
#blacklist ssb
blacklist wl
#install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS

And rebooted with flawless result ... I write this using wireless connection ^^

Don't you need internet access to download things via synaptic? If so, are these packages available for download somewhere? The only form of internet access I have is through wireless, which is why I'm using Vista right now.

EDIT: I now have an ethernet cable, so disregard this post. I've done this, now I'm rebooting to see if it works

EDIT 2: It worked!! Thank you for your help. (written using wireless)

I have a Dell Inspiron e1405 and this worked for me as well.

After struggling for a few hours with this problem ipatec's solution worked like a charm in less than 1 minute. But you have to be wired to the internet for it to work.

It's frustrating that the only hardware issue I've had with any Ubuntu releases is the wireless, and still solutions aren't that easy to find. Canonical should work on this as I bet this is a very common problem every time there's an upgrade.
