Public bug reported:

Hi,

I upgraded to 12.04 LTS. First with dist upgrade. Then, I formatted and
installed from scratch. The result is the same : a very slow internet
connection when connected in Wifi.

It is very annoying and I really hope there will be a solution in a next
update.

Thank you for your help
