View Full Version : [ubuntu] wifi antenna not detected

August 24th, 2010, 12:49 AM
Hey guys, I recently got a HP P6540FY (http://www.bestbuy.com/site/HP+Pavilion+p6540fy+Desktop+%26+23%22+LCD+Monitor+ Package/9999133000050033.p?id=pcmprd133000050033&skuId=9999133000050033) desktop computer. I want to install 500GB of the 1TB partition, but when I try the live-cd, no networks show up under the network manager. I'm on Windows 7 now, so I can post any additional information if necessary. Thanks.

I have a boatload of HPs (I work for them) and haven't had any problems with Lucid finding the networking, WiFi or cabled when upgrading.

There is a problem with a new Lucid install though. The problem is that due to an oversight, Lucid/10.04 does not have fakeroot on the install CD so in order to get the wifi going you will need to connect to a hard-wire network cable to get the files you need. Without fakeroot neither the proprietary driver or NDISWrapper will work.

Well that's extremely inconvenient. I'll just bring my modem up here for a few minutes before installing Linux, then.

To be clear, the name of the download i need to find is "fakeroot"?


I'm on live-cd right now, brought my modem upstairs. I installed fakeroot, but I'm not sure where to go from here. I updated Ubuntu, and now in network manager, under Wireless Networks it says, "Device not ready." Any ideas?

While you're connected to the internet through your wired connection, try going to System > Admistration > Hardware drivers and see if anything shows up there. Sometimes you have to restart before your driver will pop up.

I tried Hardware Drivers already, all that comes up is my graphics card. I figured I'd have to reboot, so I went ahead and began installing Linux on the second partition. I'll report back once it's installed and I'm off the live-cd, since it might work after installing and rebooting.

okay, i'm on ubuntu right now. the network still isnt showing up, and nothing under Hardware Drivers either.

It won't show up under Hardware Drivers as it doesn't need proprietary drivers.

Let's go back to the beginning - you installed Ubuntu from the Live CD? You mentioned that you "updated it" - what do you mean? Which steps did you take? The latest versions of LiveCD apparently have fakeroot, but I can't vouch for that since I've upgraded all of my systems quite a while ago.

Try this while plugged into the network:

sudo apt-get remove --purge bcmwl-modaliases
sudo apt-get install bcmwl-modaliases broadcom-sta-common

Good lucK! Hopefully this will properly install the Broadcom driver and will get your WiFi going.
