Thanks I corrected that now.

Now the win7 wifi stays connected but has no internet access.

/root >ifconfig wlan0 list scan
ADDR               AID CHAN RATE RSSI IDLE  TXSEQ  RXSEQ CAPS FLAG
0c:ee:e6:ba:6f:26    1    1  54M 26.5  135     16   8288 EPS  AQE 
RSN WME

I also see a dhcp lease for the ip address that win7 wifi says it has.

What can be the cause of no internet access on the wifi hostap?
