I am currently using Ubuntu 10.04 Precise (in dual boot with Windows 7).
Whenever I log onto Ubuntu Internet, all other computers Internet speeds plummet. Usually we have 20 Mbps download and 2 upload. However, when I log onto Ubuntu I can still get this on this computer but all other computers go to about .5 Mbps download and .6 Mbps upload.
When I log into Windows on the same machine the Internet works fine on all other computers.
My ISP is currently Time Warner. The router is SBG6580 Motorla
here is my wireless card:
