I have a Zotac Mag (with an Ath9k, and looks like the current implementation of the drivers are pretty bad. I am having the same issues (very low signal, very low speed and iregular connections). I do not have any bluetooth dongle. After reading a lot, looks like kernel 6.2.32 improves it (comes with Ubuntu Lucid Linx in April), as well as backports. For me, backports have not improved it much, but the kernel 6.2.32 yes. Speed is still lower than expected, signal also, but the reliability of the connection is improved. What I have done is use ndiswrapper with the drivers for XP which are to be found on the Zotac website. I hope this helped. Un saludo, Juanma.
