Cannot connect to WEP encrypted wireless

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:

modprobe rtl8187
dmesg | grep rtl8187
ifconfig wlan0 up
wifi-menu wlan0

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?
Thanks.

Re: Cannot connect to WEP encrypted wireless

Are you sure you have WEP encryption? What's the output of

iwlist scan

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.

Re: Cannot connect to WEP encrypted wireless

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

                    Encryption key:on
                    ESSID:"myessid"
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s

                    Extra:tsf=00000004e9bf3a3a
                    Extra: Last beacon: 2720ms ago

                    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

Re: Cannot connect to WEP encrypted wireless

I'm still having trouble with this... Any answers?

It's an ALFA AWUS036H adapter.
