I'm not runnin Ubuntu at the moment however I saw a similar bug occur with ArchLinux on an Acer Aspire One AOA150. The network connection is made but found that after a period of heavy data traffic the network card stops working and thus requires a hard reset of the device. I disable the acer_wmi module and now the issue doesn't appear again.
Btw, this is using 2.6.28.7 kernel - so issues are appearing even outside the Ubuntu world so one can assume that this isn't a distro specific issue.
To be perfectly honest, I don't know what acer_wmi does but maybe its best if it is disabled atleast on all the Acer Aspire One models.
