Hello. I'm trying to install Arch (2012.09.07) to my PC. There isn't a way to connect via cable for me so I have to do it wireless.
I have an USB wireless adapter with rtl8187 firmware. It works great in Ubuntu and Windows 7 (connects with no problems).
The thing is, my home Internet connection is WEP encrypted and I can't change that.
When installing, I do:
dmesg | grep rtl8187
ifconfig wlan0 up
And I find my network in wifi-menu. I try to connect and I type in the passphrase. The passphrase is 100% correct.
Then it says: "wlan0-myessid up"
and then: WPA Authentication Failed.
^^ Why does it say WPA when I have a WEP encrypted network and why cannot I connect to my network?
Are you sure you have WEP encryption? What's the output of
If it is WEP, I would use iwconfig (I don't know wifi-menu):
iwconfig wlan0 essid <your-essid> key s:<your key>
If it is WPA, try to configure wpa_supplicant directly.

It's wep. I tried with iwconfig too... Doesn't work.
Here's iwlist scan:
Cell 05 - Address: 00:21:63:51:87:6A Channel:1 Frequency:2.412 GHz (Channel 1) Quality=42/70 Signal level=-68 dBm Encryption key:on ESSID:"myessid" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=00000004e9bf3a3a Extra: Last beacon: 2720ms ago IE: Unknown: 000570696E6B61 IE: Unknown: 010482848B96 IE: Unknown: 030101 IE: Unknown: 2A0104 IE: Unknown: 32080C1218243048606C
With iwconfig, I did:
modprobe rtl8187 ifconfig wlan0 up iwlist wlan0 scan |less iwconfig wlan0 essid "myessid" key s:myencryptionkey dhcpcd wlan0
