(INVALID) Wireless not working anymore

[snowflake_nz]

Okay here I go again . . . making a nuisance of myself on the forums with all my silly questions.

I have Kubuntu 10.10 installed after doing a Alt +F2 update-manager -d in Ubuntu.
While using 10.04 and 10.10 I had wireless, but today it's just gone. The driver is installed (the one in Additional Drivers called Broadcom B43 wireless driver).

The thing with this is I don't personally have wireless in my house, I used ethernet or usb cable. But 2 of my friends who I regularly help out to solve some computer (actually human) errors have wireless & I just login to their wireless.
Also every week or so I login to a wireless that's not to far from me - the company actually knows that I do this as I buy the monetary voucher from them .

Last night it was still all fine and the light on my computer (Acer Aspire 3680 - ) was still on, but when I switched it on this afternoon - nothing.

Any advice for me?

EDITED 25 Oct 2010 - I've marked this as an invalid post (moderators feel free to step in here), but I opened the thread to have my problem solved or at least try to figure it out, but seeing as there are other posters asking to solve their problems & getting answers I feel that this thread no longer applies to my original question.

Re: Wireless not working anymore

Before you upgraded were you using wicd or networkmanager to connect to the wireless?

Re: Wireless not working anymore

Hi there The Liquidator
I was using networkmanager. i tried wicd (installed and then uninstalled it), didn't make a difference

Hi...

You're not a nuisance, that's what we're all here for.

Just curious, does the network manager detect or see either yours or any other connections in the area?

Also, can you run "lspci" in a terminal and post the results? It might help if we could find out your chipset.

Regards...

Re: Wireless not working anymore

Hi ardvark71

lol, txs for that.

The network manager previously detected the other wireless connections around me (I every so often bought a voucher for one of them). Just keep in mind I don't have wireless in my house. I work off either ethernet or usb from my modem.
The wireless comes in when I go to my friends' place and use the wireless from a place closeby (they do know that I use their wireless because I get a voucher from them)

Re: Wireless not working anymore

Hi again

Have you got the package B43-fwcutter installed?

[snowflake_nz]

Re: Wireless not working anymore

The Liquidator

yes, just double checked

[snowflake_nz]

Re: Wireless not working anymore

MORE INFO

I just right-clicked on the network manager widget on the taskbar and saw that the radio button for enable wireless was not ticked. I tried to tick it to enable wireless, but it won't let me.

Hope this helps

Re: Wireless not working anymore

I have a similar problem. HP DV9408nr with Broadcom 4311. I installed ubuntu then converted to Kubuntu. My wlan card only works for short periods then knocks out. Blue light on the switch is stays on but the network icon has a red x or something and there are no networks being picked up.

I have to restart to get it working again.

I have tried STA, fw-cutter, ndiswrapper, all work, but knockout after a while and i must restart to get it working again.

Anyone know whats goin on here?

[snowflake_nz]

Re: Wireless not working anymore


it seems that I'm going to have to do a fresh install of Kubuntu/Ubuntu 10.04 to get my wireless working. Problem is that this is rather urgent as I'm popping out to a friend to help her with some Gimp-tutorials on digital scrapbooking and will be needing my wireless up and running.

But at least I won't have to leave Kubuntu behind, just go back to 10.04 for now until this has been sorted.

Thanks

Re: Wireless not working anymore

@snowflake_nz: in case of laptops there is dedicated switch to turn wireless on-off. or in some there is some combination keys.. check if it is in 'on' position.
i once reinstalled system and found that the switch was unintentionally in off position :P and there was nothing wrong with wifi.

@eynestyne: if u are using the default network manager, then yes, even my laptop used to give me problem of frequent disconnection and i had to restart to connect again. but since i upgraded to 10.10. network manager has improved. though it disconnect frequently it also reconnects without restart. its better to switch to wicd. it will solve problem.
to do that:
1. go to kpackage or my fav 'muon' package manager.
2. install wicd (package manager will install the dependencies)
3. remove network-manager (package manager will remove its dependencies)
4. restart/ log off log on

hope this helps.

Re: Wireless not working anymore

I think the issue isn't a connection problem it's a detection problem, and am not sure that changing to wicd will do it. Clearly you should check that the

If you check in system /hardware does it say there is a proprietary driver available?

Otherwise I'm stumped I'm afraid.

Re: Wireless not working anymore

thanks kapli.. I will try it and post back.

I was thinking it was not a driver issue as all the drivers i have tried does the same thing.

Re: Wireless not working anymore

I have tried the WiCD and the problem is still there.
Below is the logs from i connected to when it stopped working. 14:13:51 and 14:17:01 were added after the card knocked out.

Re: Wireless not working anymore

Hi The Liquidator

the switch was the first thing that I checked. I ran the live cd of Kubuntu 10.04 and installed the additional drivers (b43 etc) and the light on the laptop worked wonderfully and it picked up the 3 or 4 wireless networks I have around me.
At first it was working on 10.10 and then it just stopped. So I'm pretty stumped on this
