OpenWRT wpa_supplicant issues

[David George]

Hi Guys,

I'm at a loose end as to how to fix wpa_supplicant on my OpenWRT box. 
I'm currently attempting to auth on the wired WAN port using wired 
802.1x wired. Here is the command i'm running and my 
wpa_supplicant.conf, which work on another OpenWRT router i have 
(broadcom based).

wpa_supplicant -c /etc/wpa_supplicant.conf -D wired -i eth0.2

wpa_supplicant.conf:

ap_scan=0
network={
	key_mgmt=IEEE8021X
	eap=TTLS
	identity="XXXXXXXXXXXXX"
	password="XXXXXXXXXXXXX"
	phase2="auth=PAP"
}

When i attempt to connect, it gets stuck authenticating. Here's the 
output using -dd:

However, if i then plug the ethernet cable into my windows desktop, 
authenticate, and then plug the cable back in to the router, 
wpa_supplicant will auth correctly with this output:

If anyone knows what's going on here i'll be extremely appreciative ...

Thanks in advance,

Dave
