My laptop, a Dell Insprion, keeps losing WiFi connectivity, and keeps showing the WiFi connection as 'limited'. WiFi on other devices like my iPhone works fine, while the laptop has problems. I looked at the power settings too, as it is sometimes set to switch off WiFi to conserve power, but it does it even when plugged in.
