Edimax EW-7711USn [Ralink RT2870] (rt2870sta) - dhcpcd timeout

Hello,

I am trying to install Arch Linux in my netbook downloading the base system over a WEP-encrypted wifi, but I have problems with my USB Wireless device when trying to run dhcpcd client...

My wifi adapter is Edimax EW-7711USn ( http://goo.gl/Gfr1N ), it uses the driver rt2870sta and the output of lsusb | grep -i edimax is:

Bus 001 Device 004: ID 7392:7711 Edimax Technology Co., Ltd EW-7711UTn nLite Wireless Adapter [Ralink RT2870]

Remembering I am using the Arch installer 2010.05 Dual Architecture CD with a i686 CPU, and kernel 2.6.33.4, i went to the wiki ( https://wiki.archlinux.org/index.php/Wi … and_rt2870 and https://wiki.archlinux.org/index.php/Rt … _conflicts ) and I did the following:

# rmmod `grep -E ^rt\([[:digit:]x]\{2\}\)\{2\}\(usb\|pci\|lib\|sta\) /proc/modules | cut -d " " -f 1`
# modprobe rt2870sta

After this, I could start my wlan0 interface, so I followed all the steps in https://wiki.archlinux.org/index.php/Wi … nual_setup to configure my WEP connection:

# ifconfig wlan0 up
# iwconfig wlan0 mode ad-hoc
# iwlist scan &> /dev/null
# iwconfig wlan0 essid "WLAN_9D" key s:asciikey
# iwconfig wlan0 channel 1 #My wifi works on channel 1
# dhcpcd wlan0

Then, after a long time, the dhcpcd client stops with a timeout error... I also tried to configure the wifi using static IP (same IP, netmask, default gateway and DNS server that was working 5 minutes before in Ubuntu Network Manager), but i could not receive data from Internet (pings to Google returned a host not found error)...

Any help will be appreciated... Also, if you need some more information, feel free to ask...

Thanks for reading such an amount of information
