Arch Linux

Description:

When running wpa_supplicant (only, no networkmanager) on this device, I experience the following problems:

* wpa_supplicant thinks it is connected to the AP, but the AP thinks there is no device connected (tested with two Android Phones)
** This happens after some minutes (~5 up to ~40)
** All network connections are not working anymore, IP is still there (from dhcp)
* Connection to some APs is established (from side of wpa_supplicant), but no IP received at all (other devices however work)
* wpa_supplicant does not scan or reassociate after waking up from suspend - I need to manually issue scan/reassociate
* wpa_supplicant disconnects from the network, claiming the key is wrong
** the key is correct
** after issueing reasscociate it usually works, however sometimes it does not
** In these case select_network XYZ sometimes solves the problem

It is possible that this is a combination problem of Linux 4.x and wpa_supplicant - however due to missing support for the mouse, I have only used this notebook with the 4.0 kernel, not with 3.x.

Additional info:
* package version(s)
* config and/or log files etc.
