Thanks for the quick answer. I don't think the AP is the problem because if I load the live with the same AP configuration it works The firmware loaded is the same in both cases as showed by the dmesg | grep firmware. lspci shows that I've got a Realtek RTL8191SEvB, which I guess is the kernel module Realtek RTL8192SE/RTL8191SE PCIe Wireless Network Adapter I tried loading all the family realtek as modules but it didn't fix it. But if wpa_supplicant does perform some activities with the card such as scanning, doesn't that mean that the correct kernel modules of the card are active?
