Why Can't Ubuntu Hold A Wireless Connection?

Posted 13 June 2012 - 09:14 AM

Quick backstory: I'm coming from a largely Windows background. I had previously tried to run Ubuntu from a pendrive, with no success.

This morning, I got it to work and liked it, so I set up a Windows 7 x64 / Ubuntu 12.04 dual boot. I chose Ubuntu because I was told it was the most user friendly, especially for someone familiar with Windows.

Now, my problem. To put it simply, Ubuntu can't hold a wireless connection with my router long enough to download a program, and when it is connected, it's quite a bit slower at the same tasks than Windows (loading GMail, for instance). Without changing anything on the router or network, Windows 7 holds that connection as long as I'd like.

What could be causing this, and more interestingly, how do I fix it? I want to enjoy my experiences with Ubuntu and Linux, but I'm really starting to get irritated with the connection. Thanks for the help.

Have you tried finding better drivers for your wifi card?

No, but I will right now. Going to reboot in Ubuntu and have a go.

EDIT:I think I need a bit more guidance - I really am clueless. I googled it, and it told me I needed to run the command '$ sudo apt-get install b43-fwcutter' and restart, which I did. After I restarted, I ran 'nm-tool' (found that on another page) and it shows the driver for the wireless as "brcmsmac". So evidently the b43-fwcutter one didn't install.

I'll keep trying - for now though, I have to pop the little one in the stroller and take a walk around the block so he'll pass out.

Ok, I'm getting nowhere here. It's been hours now, although a lot of that is due to very spotty internet anytime I switch back to Ubuntu (kinda hard to fix an Ubuntu problem in Windows), and another part to looking for that f***in ethernet cable I know I have laying around here somewhere.

In any case, what information I can find is laced with tons of stuff I don't understand. I really need someone who isn't brand new to linux systems to help me figure this out.

Info: it's a bcm43225 card.

This appears to be the one that's already installed, and reading through the readme confirms that it ships with Ubuntu. However, I imagine it's possible it's the 32 bit that's installed, so I downloaded the 64 bit and I'll pop over to Ubuntu in a sec to try and figure out what to do with it. It's a tar.gz, and the readme says I need the proper tools installed to compile it. I hope they shipped with Ubuntu as well.

Ok, I'm going to tentatively say it's fixed.

I say this because the connection is showing full-strength, as it should be since I could spit on the router from where I'm at.

The real surprise though came when I loaded up Chromium. As I said before, when the internet did work, it dragged. This time, BOOM! BOOM! BOOM! lightning speed - fast enough to (almost) make up for the hours of headache.

All I did this time around was download and install:
firmware-b43-lpphy-installer
I had previously installed b43-fwcutter; as I understand it these work in tandem.

I don't know if that's what fixed it, but it sure seems fixed.

LIGHTNING SPEED!
