Introduction

As this Belkin router comes in several versions.

If you have a 4 MB model, you can reflash the router with the full version generic firmware from within the

routers web interface after dd-wrt is installed as long as you check the filesize of the build you are flashing

and make sure it not larger than what is allowed in your Belkin router. See the peacock announcement at the

start of the broadcom forum, notes 3 and 4 for further information:

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486

v1000, and v1111, have 4 MB flash while v1444 has only a 2 MB flash. You have to flash 2 MB routers with

the 2 MB micro firmware. There is information that suggests that flashing firmware over 3.5MB will brick a

v1000

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=29520&postdays=0&postorder=asc&start=180#239052

v1232a and all others with Broadcom 4710 chips require VINT builds.

v1444 supports Micro-plus

v2000 has a different switch chip and flash chip than earlier versions so a special build is required. You will

temporarily lose the functionality of the switch and will only be able to connect wirelessly after flashing. (see

flashing instructions and instructions for enabling the switch ports [1]) v2000 supports Micro-plus

v3000 should work, but attempts to flash it have been unsuccessful with current versions of DD-WRT.

Attempting to flash a v3000 could brick your router. (psuftbl has had success with v3000)

v4000 and higher appear to be based on the TI chipset found in the Linksys WRT54GC.

Flashing Instructions

Warning: These instructions will brick v1212 and v1213 Belkin F5D7231-4 routers, apparently without

a hope of fixing them short of some rewiring. See the forum posts here [2] for possible help un-bricking one

of these units.

Download the latest micro firmware (dd-wrt.v24_micro_generic.bin). See Where do I download

firmware? for links. Located in the broadcom folder.

Reset router to factory defaults. Unplug the router.2. Connect your computer directly to one of the LAN ports on the router.3. The router starts up with IP address 192.168.2.1. Set your computer's IP address manually to the

following setting: IP Address: 192.168.2.2, Subnet Mask: 255.255.255.0, Default Gateway: leave

blank.

Go to Start->Run->"cmd" and press Enter.5. Change your directory to the folder containing the firmware image. Ex. cd "C:\Documents and

Settings\All Users\Desktop"

Type tftp -i 192.168.2.1 PUT (file name of firmware image) For example:

tftp -i 192.168.2.1 PUT dd-wrt.v24_micro_generic.bin.Do not press enter

yet.

Connect the power to the Belkin.8. All port LEDs will illuminate.9. After a few seconds, all LEDs except the one you are connected to will turn off. Wait exactly one

second and hit enter to execute the command. If you get a timeout error just try again. (Also try

running tftp right before powering up.) If you continue to have trouble with this step check out the

alternative method below.

10.

The LED on the LAN port will flash rapidly for a while after which the power button will flash

rapidly for a while. Be patient and wait for the power light to stop flashing. Wait a couple more

seconds.

11.

Power cycle the router. (unplug the power, wait a few seconds, plug it back in).12. Set your IP address back to automatic (DHCP), or set it to something beginning with 192.168.1.13. The router is now accessible at http://192.168.1.1/14. The user name is 'root' and the password is 'admin'15. Enjoy your DD-WRT router16.

It may be easier to use a GUI TFTP Utility

Follow steps listed in the method above until you finish the part where you set your computer's IP

address to 192.168.2.2

Download a GUI tftp tool from here or use tftpd32 (http://tftpd32.jounin.net/)2. Start TFTP program and set server to: 192.168.2.1 and for the file part, put the location of your

"dd-wrt.v24_micro_generic.bin" file. No password required.

Set retries to 20.4. Power up router.5. Click upgrade and then hit the reset button on your router. If program doesn't catch the Belkin's TFTP

window, just hit reset again. The tftp program will let you know when it is upgrading and succeeds.

TFTP is only active during the first few seconds of boot. If you have problems catching the small TFTP

window, try setting your NIC to 10mbps half duplex. This helps the NIC connect quicker. You can also try

using a hub or switch between the router and PC.

Flashing Instructions 2

Second Alternative for Flashing F5D7230-4

If you're having difficulty with either of the above methods (or just don't feel like going through all the hoops

required) there is a much simpler method that may work.

Reset the router to factory defaults.1. Set your computer's IP address to 192.168.2.2 as described above.2. Plug your computer into the router and power the router on.3. In a command prompt (what you get by going to Run in the start menu) type out the tftp command

line but do not hit enter yet.

Press and release the reset button on the back of the router.5. Almost immediately hit enter in the command prompt to run the tftp command you typed out.6. If tftp tells you the file was sent successfully wait a few seconds, unplug the router, then plug it back

in. If it says the connection timed out or the transfer failed, prepare the tftp command line again

(hitting the up arrow key should do it) and repeat the previous two steps.

Connect to 192.168.1.1 to configure (and enjoy) your vastly improved router.8.

After trying the first two methods a few times (the first method several times in particular) I managed to get

my v1444 flashed in one try (!) using this method. As such I am unsure of the exact delay between resetting

the router and starting TFTP, but it was definitely less than a second. At the very least this method is much

more enjoyable than unplugging and re-plugging your router over and over again.

Using v2000 Or FD57231-4 As A Wireless Client or Access

Point with DD-WRT

(borrowed from http://forum.bsr-clan.de/ftopic8732.html)

The Belkin F5D7230-4 v2000/FD57231-4 (with screws not under label) are still not completely functional

with DD-WRT, but it can be used as either a wireless access-point or a wireless client. The reason for this

limitation is due to the fact that the current robo-switch is unable to properly configure the vlan with this

router's implementation of the BCM5325EKQM switch chip. By bypassing the vlan stuff we can get limited

functionality from this router. In order to load DD-WRT micro you must tftp it on to the router. These

instructions are for the v24 build of DD-WRT micro not the multi-language version which seems to have

stripped out the reboot, ls and other shell commands.

A) Belkin F5D7230-4 v2000 as a wireless client.

1) Connect to the router wirelessly

2) Telnet to the router and sign in or use a serial console cable

3) Enter the commands below:

Belkin_F5D7230-4_v2xxx_and_Lower

Linux Instructions for Flashing F5D7230-4 4

nvram set lan_ifnames="eth0 vlan0"

nvram set port0vlans=0

nvram set lan_ifname=eth0

nvram set wan_ifname=vlan1

nvram set wan_ifnames=vlan1

nvram commit

reboot

4) After the reboot, unplug the router and plug it back in. When it starts back up your LAN ports should be

active. The router's default IP address is 192.168.1.1. Just use the web interface via the LAN port to configure

the router as a wireless client.

B) Belkin F5D7230-4 v2000 as a wireless access point

1) Connect to the router wirelessly

2) Telnet to the router and sign in or use a serial console cable

3) Enter the commands below:

nvram set lan_ifnames="vlan0 eth1"

nvram set port0vlans=1

nvram set remote_management=1

nvram set lan_ifname="br0"

nvram set wan_ifname=eth0

nvram set wan_ifnames=eth0

nvram commit

reboot

4) After the reboot, unplug the router and plug it back in. When it starts back up your WAN port should be

active. The router's default IP address is 192.168.1.1. Just use the web interface via the WLAN port to

configure the router as an access-point.

If you enter in the wrong setting or can not access your router you can always hold down the reset button to

restore it to the factory defaults. Remember that we are bypassing all the VLAN stuff so some of the web

configurations will not work.
