Ok, so, I just upgraded to 11.04 from my existing 10.10 install.
Everything works fine, but my wireless speed dropped from about 29.5 mb/s to about .86 mb/s
It is now unbearable slow.

Please tell me why/how to fix this.

I had to plug into my ethernet just to write this.

I'm relatively new to linux/ubuntu and I can't figure out the fix on my own.
I've gone to "additional drivers" and it's just says there aren't any,

I ask you all for help as soon as possible, I don't want to re install 10.10 from the usb stick and lose all my data. (Also, I kinda like Narwhal)

I have the same problem. After I upgraded to 11.04, I found huge speed drop of my wireless connection. I tried to ping a local machine, turned out that 30% packages loss. And this would never happen in my 10.10 or windows.
I am using Dlink dwa-556 wireless card.
