In Windows 7 the signal is excellent, stable and strong. I use the
netbook for every home, but in Ubuntu you can only connect a few meters
away. In my university can not connect because the signal is too weak.
In Windows 7 is okay. Everyone in my building at the university can
connect very well with Windows. Who uses computer ath9k driver, no.

Just search on Google to know that everyone who uses Atheros AR9285 have problems, even with computer hardware certified by Canonical:
