Wireless connection keeps dropping

Asked by Wladston Viana on 2007-05-21

Guys,

I have a Toshiba Satellite R20 laptop, with Ubuntu Feisty installed on it. It has an Atheros Wifi card.

Very frequently, my wireless connection keeps dropping (The ballon keeps saying "connected" and "disconnected", in a loop)

That never happens when I'm on Windows Vista, also installed on the lappie.

Can someone help troubleshoot the problem ?

What application are you using to manage your wireless connection?
Are you also plugged into a wired network simultaneously?

Wladston Viana (wladston) said : #3

SageMassa, I'm not using any special application to manage my connection. I guess I'm using the default Ubuntu manager. Also, I not using two connections simultaneosly.

I'm using a Dlink wifi-router, the DI-624.

Massimo, here you go :

I belive this is related to Bug #64173 in network-manager.

I dont use this utility so i removed it from my system but a number of fixes are listed under the noted bug.
You may want to try managing your wireless with a tool like madwifi or wifi-radar and disable or remove network manager.

I hope this helps

Thanks SageMassa, that solved my question.

Thanks SageMassa!

Well, I rather not spend yet more time trying to make it work. I'll keep not using Ubuntu on the lappie for a whil, untill I get more hardware support.
