I just started using Ubuntu on my secondary PC, I don't really know my way around it yet. I had originally gotten my wireless card (a Linksys) to work using the broadcomm workaround since linksys didn't have any drivers for ubuntu. However, I updated something recently and now my card doesn't detect any wireless networks. I don't have the problem with my XP laptop. Any thoughts as to what I might have done? Keep in mind I know almost nothing about Ubuntu at this point. Thanks for any help you can offer.
What was updated? It might be a matter of re-doing the work around or if a new driver/module has been made available it might just be a matter of setting the card up properly. There is little point in reinstalling since as soon as you update it will probably break again. Unfortunately its a bit difficult to diagnose with what you've given us.
If it is broadcom then you need to have the B43 enabled in the kernel. You do not need linksys drivers as they are not the manufacturer of the chip that runs the wifi card. I'm not sure how Ubuntu does kernel updates but look for one with that support enabled. You will need mac80211, nl80211 netlink, Wireless extensions sysfs, then B43, and possibly B43 debugging. Modules are as follows: NL80211, WIRELESS_EXT_SYSFS, MAC80211, B43, B43_DEBUG
Yeah I'm not really sure what I updated, I didn't check it like I usually do as I was in a rush to leave. And @ C-Sniper, I'm really new at this. I have almost no idea what most of that stuff is.
Ah, I have been running Slackware for 2.5 yrs now and know my way around linux fairly well. Basically, While Linsys makes your wireless card, the actual wireless chip is from Broadcom. You will need the drivers for the Chip, not the manufacturer of the entire card. For example, I have a Trend-Net card that has an Atheros Chip. I need the Atheros Drivers not anything from Trend-Net. I have never used Ubuntu, but IIRC they release their own kernels which is the main part of the operating system and contains all the driver support. (Or a good chunk of it atleast) Could you post an "su -c lsmod" and "lspci -v"?
If you can explain to me how to do it, sure thing. Is that something I have to input into the terminal? I'm a total noob when it comes to Linux so bear with me here guys. Sorry.
Open the terminal and type "lsmod" if you get an error saying there is no such command then input "su -c lsmod" it will ask for your password then post some information. Same thing with the "lspci -v" This has to be done in a terminal.

you forgot the space between the "lspci" and "-v" no su required. Also, i believe the reason the card isn't working is because: 1. the B43 modules is not loaded 2. You *probably* (or Ubuntu) has probably not compiled the firmware required for the B43 module. 3. Ubuntu is a piece. (Sorry loyal follower of Slackware) Can you try some other things as well? In the terminal: apt-get B43 apt-get fw-cutter In any case google Ubuntu and B43. This should get you the answers better than i can try.

Bump. Any updates for me fellas? I use that computer as storage for my media files and it's been really inconvenient being unable to access my stuff from my other computer.
The packages are unfortunately named something slightly different and apt isn't clever enough to know what you mean. Open a shell and type Code: sudo aptitude -u aptitude is a curses based front end for apt and the -u flag tells it to update Now press "/", that brings up a search box in that start typing b43 and then hit "n" till you find the package then "+" to add it to the install que. Now same again with fw-cutter. Once you've added them both hit "g" to install and follow the on screen directions. for reference on my lenny box there is only one file i think its the only one you need at itscalled Code: b43-fwcutter Once your done hit "q" to quit beyond that i know little about wireless perhaps some one can assist further.
You don't need B43, you need Ralink. RT61 is you chip. I don't know why the Broadcom workaround worked but you need to get the RT61 drivers. (I believe they are in the kernel.) If not just Google them
