Can't connect wirelessly anymore

[epikvision]

I suggest that you use the latest version of ubuntu, which is 12.04. Perhaps, your problems will be solved with a fresh install.

Hi, the information you posted shows the wireless is on so do not put the wireless button anymore.

Go to network manger do you see your network name? is enable wireless checked?

If by "network manager" you mean System Settings > Network then no, I only see two options: Wired (the one I'm using now) and Network Proxy.

Please post the output of:

nm-tool

~$ nm-tool

Can you connect?
Thanks

Well, I just took out the ethernet cable and waited to see if anything changed. It didn't appear to, and the wifi light on the laptop is still off.

Cheers.

Thanks, but I'd rather not--at least not just yet--unless I have to as one of my favourite applications supposedly doesn't work very well in that version.

Hi, please do:

echo "blacklist wl" | sudo tee -a /etc/modprobe.d/blacklist.conf

sudo modprobe b43

Reboot

Does the wireless come on?
Thanks

I was about to reboot it after I typed the second command in but the wifi light turned on. When I disconnected the ethernet, the computer detected my router and has just connected to it. I just posted this with it so it seems to work (thanks!!)--do I still need to reboot it?

[wildmanne39]

Yes reboot and make sure the wireless comes back on if not we will have to make the driver load at boot, if it does please use thread tools at the top of the page to mark the thread solved.
Thanks

Yeah, it came back on no problem. Once again, thank you sooooooooo much, you have no idea how long that had been bugging me!

Hi, your welcome glad to help!!!
Enjoy
