很多人抱怨极路由没有提供有线中继功能，以下教程使用小米路由器作为主路由器(upstream router), 极2路由作为有线中继. 这样可以比无线中继更稳定，性能更好。

随手用英文记录步骤，懒得翻译了。

注意： 这种方式有点hacking, 出了问题后果自负。

目前存在的问题是： 极路由的云插件没法用了，不过这个我觉得不是大问题。

The basic idea is to turn Gee into a wireless switcher.

0. Do NOT connect Gee router to any upstream router.

1. Connect to the default HiWiFi_XXXXX wifi access point.

2. Go to management page of Gee router.

3. Keep the dhcp function enabled in Gee.

4. Modify the admin page ip into the same segment as upstream router. e.g. 192.168.31.2. So that you can manage Gee within the upstream router‘s segment.

5. Gee will ask you to reboot. Reboot it.

6. Visit the management page at the new IP set in step 3. e.g. 192.168.31.2
   (btw, you will find the dhcp segment in Gee automatically changed to 192.168.31.* accordingly.)

7. Rename and add pwd for 2.4G and 5G wifi AP. Then the default HiWiFi_XXXXX access point will disappear. And if you type ipconfig command line, you will find no ip configuration now.

8. Connect to the new APs.

9. Connect Gee‘s LAN (not WAN) port to upstream router LAN port with a wire.

10. Disable Gee‘s DHCP function.

11. Now you can use Gee as a wireless switcher.
     (btw, if you go check Gee‘s Internet setting tab, it still says "no connection to Internet". But anyway. Just leave it as automatic mode and change nothing.)

On my box, 192.168.31.1 is the Mi router management page, 192.168.31.2 is the Gee router management page. Quite handy for me.
Both Mi and Gee are in the same segment, which is desired by many...
