I got a new wireless router (TP-Link TL-WR741ND) to use a wireless repeater,
but i found the software in it cannot do this.
i searched the internet and here is what i did
1- Download Gargoyle firmware for this router (gargoyle_1.4.7-ar71xx-tl-wr741nd-v1-squashfs-factory.bin) from here (gargoyle-router website)
2- Install the new firmware to the router and reboot.
3- Connect ethernet cable between PC and Router
4- Browse to http://192.168.1.1
5- Login password is password
6- Change password
7- Configure time
8- Select Wireless Bridge
9- Configure your gateway and password
10- Reboot the router
