Details..... Gear.....

i have setup my repeater like this.
wireless mode :wds slave ,i have also set it on dynamic wds on bridge1
same ssid ,frequency as main AP.created a bridge where i have added my ether1 and wlan to the port.
i have not set any dhcp because i want all dhcp to come from main AP.

the problem is that it seems not to repeat the signal.if i connect through cable am able to pickup ip address form
main AP.
