Upgrading to a Newer Version of DD-WRT
======================================
If DD-WRT is already installed on your router,
you can simply upgrade to a new version via the web interface or TFTP.
However, it is highly recommended that you restore the router to defaults using the reset button before and after flash.

Cautions
=========
DO NOT USE THE "ROUTER DATABASE" AS A SUBSTITUTE FOR READING THE WIKI!
Ref: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486


webgui
======
Your default username/password is always root/admin.

If you can't get into your webgui, try telnet or ssh, where the username is always root.

You have to hit "apply" for your changes to be made permanent.
"Save" just stores them temporarily in memory without actually writing them.


Options
=========
Assign WAN Port to Switch : Optionally enable this to use the WAN port as another LAN port

Static DHCP address assignments = (จ่าย ip เดิมให้กับ client)

Additional DDNS support (รองรับ dyndns ทำให้เข้าถึง router ได้ถึงแม้ว่า ip address จะเปลี่ยน)

Client isolation mode (กันไม่ให้ลูกข่ายที่ใช้งาน wireless ต่อถึงกันได้ จะติดต่อได้กับ access point เท่านั้น)

Do not raise your TX value
should fix signal issues with better antennas not power.
Many routers do much better with LOWER TX values,
around 40-50 especially those with the crappy internal antennas (linksys ashtrays).

ยิ่งปรับ tx power เยอะ, speed รับส่ง ยิ่งต่ำ

Telnet
=======
When asked for the username, enter root (even if you changed username in web interface)
When asked for the password, enter your router's password (default "admin")
