RTL8187 connecting to WPA2.. DHCP problem

[jpm11]

Ok, so I've read all the threads and searched the whole internet for many hrs and can't resolve this.

I have the Alfa 500mw RTL8187. I installed ndiswrapper and got it to associate with my AP properly (via wpa_supplicant). When I run DHCP, it just times out.

Does anyone have this setup working? I'd love some advice.

Thank you

You have posted on the wrong forum but anyways are you sure the DHCP server is working in the first place? In other words, are other nodes in the same network able to get dynamic IPs? Secondly I would try wpa_supplicant w/ the verbose option to make sure it is really associated:

wpa_supplicant -d -D wext -i wlan0 -c /etc/wpa/ertech_supplicant.conf

Lastly configure the network yourself:

bt ~ # ifconfig wlan0 up
bt ~ # ifconfig wlan0 192.168.1.24 netmask 255.255.255.0
bt ~ # route add default gw 192.168.1.1
bt ~ # echo "nameserver 192.168.1.1" > /etc/resolv.conf

Modify the above to your respective network settings. Hope it helps!

Hey thanks for your response.

I'm certain that atleast with Layer2 I'm associated to my router because I can see MAC address connected via my dd-wrt's web page.

root@bt:~# wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant.conf

DHCP still times out

Setting it manually works but I can't ping the gateway (192.168.1.1)

root@bt:~# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
From 192.168.1.24 icmp_seq=1 Destination Host Unreachable

From 192.168.1.24 icmp_seq=4 Destination Host Unreachable
From 192.168.1.24 icmp_seq=5 Destination Host Unreachable

I'm stumped. I have no problems using this card in a monitor mode but it just can't associate.

I'm also running this inside vmware but since it's a USB card then the hardware device is available directly so I don't see how this can make a diff.

Thank you

How do yoou run dhcp?

You shoud know that dhcpcd is "depricated" (i just have to use it).
Should use dhclient <dev>

Yep, I run "dhclient wlan0"

It just times out

Is it just the gateway you can't ping or everything including public ips? To make sure VMware is not causing the problem, run the Live CD and try the same connection.

Can't ping anything... Doesn't work with VMWare or Live CD. I think WPA2 is culprit. Going to try connecting over WEP or Open.
