Hey everyone, I'm trying to install Arch. The first time I tried installing everything worked fine, even the wifi, which usually doesn't work with linux. However, my laptop battery died in the middle of downloading packages because I was careless and hadn't plugged it in. Now, when I enter "ip link set wlp2s0f0 up", it doesn't set the interface up. Strangely, when I reboot, the interface is renamed to wlan0 (that's what it was when the wifi worked), even though the wiki says it shouldn't. Running "modprobe -r rtl8192ce && modprobe rtl8192ce" changes the interface name to wlp2s0f0. "ip link" gives me (besides the lo interface) 3: wlp2s0f0: mtu 1500 qdisc nook state DOWN mode DEFAULT qlen 1000 link/ether 00:e0:4c:81:92:53 brd ff:ff:ff:ff:ff:ff Before, it gave me: 2: wlan0: mtu 1500 qdisc mq state DOWN mode DEFAULT qlen 1000 link/ether 24:ec:99:4c:60:1f brd ff:ff:ff:ff:ff:ff What else can I try? Lspci and dmesg show that the firmware has been loaded and that the card has been recognized.

The first thing I would try would be to move /etc/udev/rules.d/network_persistent.rules to root's home directory, and reboot. That way you should wind up with the wlp2s0f0 name whether it's working or not, otherwise. =-Jameson
