The current Area31 boot image (5.1 beta) does not support wlan cards such as the Intel N6300 (Centrino) which makes installation quite frustrating on not-so-old but otherwise quite capable machines from 2012-2014, if wired ethernet is not available. Additionally, the previous system rescue CD 4.9.0 has been deleted so that alternative for installing on those machines is not available anymore (unless you search the Internet Archive for it).
