Change AP Router TL-WR340G+ Menu from Chinese to English

I bought an AP Route TL-WR340G+ when I was in China. After I tried to log in into the menu I don't know what to do since all menus are in Chinese .. of course :), I start to find the menu that can change the language but i couldn't find one, and I start to browse to find out how to change the language but still could find the answer that satisfied me.

I tried to look at vendor website www.tplink.com. First time I do is to find out the English manual, thanks God I found it but for TL-WR340 it is similar. After exploring the manual I got the idea of what is the menu on my AP router.

Obviousely, the firmware of the router can be upgrade but this is for TL-WR340G NOT TL-WR340G+ (look at "+" sign; and until now I still don't have any idea what is the different between the two of them).

I dare my self to upgrade it, the purpose is very simple ; so I can play around with my router because the menu in English :) and because in the website it says " this firmware can be used for version 5 ( I look at my router and it says version 5, so make sure you also have same version ) "

And this is step-by-step what I did to change my AP router so it has English menu, and NO GUARANTY

1. English Manual and Firmware update can be downloaded at vendor site

2. Make sure you make back up of your AP Router setting

3. In Chinese menu find out where the menu for upgrade firmware ( you can do it by reading the  English manual and find out which place is for upgrading firmware )

4. Upgrade it ( DO NOT turn of your computer while upgrade firmware processing .. it could damage your AP Router . So just wait until the process is finish and the AP Router will restart by it self)

5. Voila .. My router menu now all in English :D
