@enavj

why did u flash the custom redboot. did the orig one not work?

btw the dir300 build doesnt show wireless cause its different on the 2315 platform then on the 2317.

if this is still a current projekt i might be able to get u a build which should work or at least shows wifi.

I'm also interested to flash this router with DD-WRT.

@Sash

Can you compile a build with working Wi-Fi ?
I think that, with some adjustments, this router will reborn with dd-wrt inside.

P.S I can confirm enavj expreriments..

First patch redboot configuration with brainslayer tool
Second flash DIR-300 firmware, that is fully working except wifi...

Hey all,

This post has been a great help for me.

I do think there is a demand for this router, and I would love to see & use a 4mb firmware (like the La Fonera) that supports the WIFI, otherwise it looks stupid having a router with antennas and acting like a regular router.

I have too tried all suggested operations and have happily got it working.

A few notes :

I have not managed to access the redboot via 192.168.80.20, i used this suggested tool to make redboot available at the default 192.168.1.1 ip.

this could save you some valuable time.

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=44506

Also another important tip is to make sure Firewalls are off (windows firewall for instance), this killed my TFTP transfers about 5 times until i figured it out.

The entire procedure took about 3-4 hours (not fully working on this) and I'm not yet sure if its worthwhile, depends on how this router now functions.

Appreciate all your help, thanks.

Hey sash,

Maybe this was a waste of my time, dd-wrt does not save configuration, tried hard-reset twice + using IE and not firefox..

How do I get lspci to run? I telnet-ed to the router and lspci cant be found ..

Hi all, I have one good things for you. I'm able to boot and run successfully OpenWrt. Everything works ok except WiFi LED indicator.

I'll write tuto(step by step guide) how to do it. For people, that bricked the router, I have solution too(serial console). Everything will be asap on the OpenWrt wiki.

Which guide do you follow?

There is no ap61.{rom, ram} in link I've given you.
Be aware of bricking your router! If you don't know what you are doing don't flash it.

It is _not_ required for this router to run wrt. ap61.{rom, ram} is probably another RedBoot(bootloader) and in case of failure there is no easy way to recover.

Have you correctly configured and started TFTP server on your computer?

And have you put these(kernel and rootfs) files into its root directory?

I've successfully installed an OpenWRT trunk yesterday...
It works flawlessly.
WAN and LAN ports are automatically adjusted, Wi-Fi works in Station and AP mode at the same time without problems.
However i prefer DD-WRT and so i'm waiting for it's official support
