Flashing Instructions
In order to flash your router you need to do the following steps:
- Download TFTP32/TFTP64
- See Where do I download firmware? for links to firmware. Look in the dlink-dir400 folder.
- Download Putty client or you can use any telnet clients(try to stay away from Windows built in telnet)
- Change your local IP adress to a static 192.168.0.2 and subnet mask to 255.255.255.0
- Connect an ethernet cable between your computer and DIR-400’s WAN port
- Prepare Putty telnet session — 192.168.0.1 port 9000
- Start pinging your router through a command line. Type ping 192.168.0.1 -n 900 (You don’t really need to ping that many times)
- Power DIR-400 router on and wait for 2nd successful ping and then initiate putty telnet session.
- Press CTRL-C as soon as you see that boot script is executing (if you are using Putty ver. 0.60 or newer then you don’t have to worry about this)
- Start TFTP server with linux.bin in TFTP root directory
If you did everything right then you should see the following on the window of putty:
