wpa_supplicant version 2.10 broke authentication for many users, as it now needs USE="tkip" which was not the case with 2.9 or earlier. See e.g. https://forums.gentoo.org/viewtopic-t-1147741.html Reproducible: Always Steps to Reproduce: 1. try to use wpa_supplicant v.2.10 with default USE flags to connect to a WiFi needing TKIP. See it fails (cf. https://forums.gentoo.org/viewtopic-t-1147741.html) 2. rebuild with USE="tkip". Test, it will resume working. Actual Results: wpa_supplicant v.2.10 with default USE flags to connect to a WiFi needing TKIP does not work. This is a regression w.r.t. 2.9. Expected Results: it should keep working with default USE flags add tkip to default USE flags of wpa_supplicant
