Hi,

I'm a terrible newbie when it comes to Ubuntu, but I've always been able to muddle along until now. The problem is that my internal wireless card seems to have disappeared from the face of the earth, as has its hardware driver. This thing has been in my computer for years now and I've never had a problem with it, the flip-side being that I no longer have any idea what make it is. I've tried searching for driver updates and updating everything in sight, but nothing seems to work. Could anyone spare some advice for an utterly bewildered newbie? I'm using my mobile to tether my desktop to the wireless network in the house right now and it's not ideal.

Thank you so much (in advance) for attempting to help.

Just found that it is a Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express, or at least that is what the terminal tells me.

Hello, welcome to the Forum.

Could you please post the terminal output of
lspci -vnn
There probably will be others needed as well so this is the start.

Hi you are right it does seem to have disappeared.

Some more commands to run please
rfkill list all and
lshw -C network
This time could you put the output between [code] tags by clicking on the # at the top of the message pane. This makes the information easier to read.

Thank you.

Thank you for all your help, clearly saint-like patience is a forte of linux masters!

Here is the code, the first command came up with nothing though:

Hello again.
This part of your last post

description: Ethernet interface
physical id: 1
logical name: usb0
serial: 0e:f4:a2:48:8b:8e

configuration: broadcast=yes driver=rndis_host driverversion=22-Aug-2005 firmware=RNDIS device ip=192.168.42.184 multicast=yes I do not understand.

Is it because you have a mobile phone connected or do you have a rare instance of an usb wireless chip hard-wired to the motherboard.
If it is the phone then I think that in all probability the wireless module might have died or there is a broken wire somewhere.
If the latter is true could you post the output of
lsusb

Thank you

PS thank you for the compliment of being a Linux Master. In all honesty though I am really a newbie at this, just a glutton for punishment. lol

I have a mobile phone connected right now, so that explains that. But why would the wireless card just die? WHY? How could it do this to me etc...
