The bug is not necessarily caused by rtl8192ce. I have never seen this problem on my system. I would also expect a stack dump. Anyone know what is needed to get one here? I do have some further questions. Which variant of the RTL8188CE do you have? Use 'lspci -nn' to tell. Does ARCH have an updated kernel later than 3.0? What version of wpa-supplicant? Are you using NetworkManager? If so, what version? Is your desktop KDE, Gnome, or something else? If NM, what applet and version? If not NM, how do you connect? Larry
