Description:
On the two N550D we got, the WiFi card is compatible with the ath9k driver.
The laptop has a Radeon GPU that is probably inside the (N550?) AMD processor chip.
The screen was also glossy which makes it hard to use due to adverse health effect with it (https://en.wikipedia.org/wiki/Glossy_display#Adverse_health_effects) but gives better colors for movies in the dark.
