 +**intro**
 +  * as E1200 is a low end wifi router, it doesn'​t have feature to extending current main wifi router coverage, so you need to use below method to use 3rd party firmware to enable that feature, so called "wifi repeater"​ or "wifi extender"​

 +  * Detail steps:
 +    - Flash the firmware into E1200, following 100% from step 1 to 11 on http://​dd-wrt.com/​wiki/​index.php/​Linksys_E1200
 +    - Go wifi repeater setup guide : http://​davidvielmetter.com/​tricks/​turn-your-linksys-e1500-into-a-wireless-repeater/​
 +    - Note: this article use E1500 router, so you can jump to "how to get it configured as a Repeater Bridge"​ part for the actual info you need,
 +    - better use one computer/​phone/​tablet to login current wifi router control panel to check its wireless info like:
 +        * wireless network SSID: (wifi_name_show_in_device)
 +        * wireless network mode : (mixed, b, g, n, as the network speed mode)
 +        * wireless security mode: (most likely WPA2 Personal, but check to confirm )
 +        * WPA algoritms: (most likely like AES)
 +        * WPA shared key: (basically your current wifi router password)
 +        * DHCP IP range: (something like 192.168.x.x-192.168.x.x)
 +        * DHCP subnet (most likely 255.255.255.0)
 +        * Router IP (most likely 192.168.1.1 or 192.168.0.1)
 +      - at the same time, use another computer to wifi connect to your DD-WRT name wifi router network, then go page 192.168.1.1 in browser using DD-WRT default user: "​root"​ pass: "​admin"​ to go DD-WRT web control panel
 +    - Real config part
 +      - Setup Tab -> Basic Setup page <​code>​
 +IP address: 192.168.x.250 (x is what about 0 or 1 in your current wifi router info above, 250 is a big number most likely not taken by other device in current wifi device list, like 101,102)
 +subnet mask: 255.255.255.0
 +Gateway: 192.168.x.1 (x is 0 or 1 based on your current wifi rounter info)
 +Local DNS: 192.168.x.1 (same as above)
 +</​code>​
 +       - "​save"​ button and "apply setting"​ button, wait 30s for it reboot
 +       - wifi connect to your DD-WRT name wifi router network Again, but this time, go page 192.168.x.250 as above step in browser, login DD-WRT default user: "​root"​ pass: "​admin"​ to go DD-WRT web control panel
 +       - Wireless Tab -> Basic Setting page <​code>​Wireless mode: Repeater Bridge</​code>​
 +         - "​save"​ button and continue on same page <​code>​
 +current wifi network mode: (mixed, b, g, n choice as in current main wifi router setting)
 +current wifi SSID: (the main wifi router wifi name)
 +sensitivity range: 2000
 +network configuration:​ bridge
 +
 +Click Add 1 virtual inferface (basically this router works as wifi extender like setting config)
 +wireless SSID: wifi_name_like_main_extender
 +wireless SSID broadcast: Broadcast
 +AP isolation: disable
 +network config: Bridged
 +</​code>​
 +          - "​save"​ button again and make sure above info filled
 +        - Wireless Tab -> Wireless security page <​code>​
 +Physical interface wl0: (main wifi info)
 +security mode: (like WPA2 Personal based on main wifi info)
 +WPA algorithms: (like AES based on main wifi info)
 +WPA shared key: main_wifi_password
 +
 +virtual interface wl0.1 (so-called this extender wifi info)
 +security mode: (same as above)
 +WPA algorithms: (same as above)
 +WPA sahred key: (same as above)
 +key renewal interval: 3600
 +</​code>​
 +        - "​save"​ button
 +        - Setup Tab -> Advanced Routing page <​code>​Operating mode: Router</​code>​
 +        - "​save"​ button
 +        - Services Tab -> Services page <​code>​DNSmasq:​ disabled</​code>​
 +        - "​save"​ button
 +        - Security Tab -> Firewall <​code>​ uncheck all box</​code>​
 +          - "​save"​ button
 +          - same page <​code>​SPI Firewall: disabled</​code>​
 +          - "​save"​ button
 +        - "Apply settings"​ button, wait for reboot
 +      - Now, you shoulder see 2 wifi network in your device
 +        * your main wifi name
 +        * your so-called extender wifi name
 +      - put your extender wifi router in the middle way, so it cover all the house
