tl;dr After reading the Arch wiki articles on installation, wireless setup and WPA supplicant, trying the suggestions below and a host of forum threads, I'm unable to get either of the following cards to connect to my wireless network when booting the Arch Linux 2013-09-01 ISO:
- Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter (ID 7392:7811)
- Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter aka. Bolse® 300Mbps Wifi Wireless N USB Micro Mini Adapter (ID 0bda:8178)
Approach 1 (default):
[SSID] + wpa 10
After a timeout it reports that the connection failed. If I run
wifi-menu a second time it doesn't ask for a password, but when finished it finally gives some debug hints:
Job for netctl@wlp0s29f7u5\x2dBTHub4\x2dGRK6.service failed. See 'systemctl status netctl@wlp0s29f7u5\x2dBTHub4\x2dGRK6.service' and 'journalctl -xn' for details.
The former reports that the service is "loaded" but not "active" (literally
inactive (dead)). The latter says:
WPA association/authentication failed for interface 'wlp0s29f7u5'
Does this mean the key in
/etc/netctl/wlp0s29f7u5-BTHub4-GRK6 is wrong? I can't tell when programs want the actual Wi-Fi password and when they want something like the
psk value from
man 5 netctl.profile doesn't say, for example).
# echo 'ctrl_interface=/var/run/wpa_supplicant' > wifi.conf # wpa_passphrase essid passphrase >> wifi.conf # wpa_supplicant -B -i interface -c wifi.conf Successfully initialized wpa_supplicant # dhcpcd -A interface [...] timed out exited
I tried connecting with
iw directly, but got some strange output:
# iw dev wlp0s26f7u5 connect [SSID] command failed: Operation not supported (-95)
