iight, solved it!!!!! i suppose i'll post the procedure i found.




REFLASHING THE ROUTER WHEN THE DIAG LIGHT IS BLINKING

The blinking diag light usually means that the firmware is corrupted or incomplete.
Fortunately, this is recoverable by following the procedure below.

1) Remove all connected computers from the router except for one computer (preferably,
your best computer).

2) Reset the router by holding down the reset button for at least 10 seconds.

3) Go to control panel, double click on network, then double click on TCP/IP -> for
your network card. Go to IP ADDRESS, and specify it using the following:
ip = 192.168.1.2 subnet = 255.255.255.0
Click OK.

4) Next, if you have a 10/100 network card, double click on your network card adapter
under network configuration. Click on the ADVANCED TAB, and you should see a
properties option for "media type" or "connection type" or "mode" that currently
has its value set to "auto sense" or "auto". If you click on the arrow button
next to value you'll see other selectable modes. Change the value and select the
lowest mode, which may be something like "10T half" or "10 hd" or just "10" etc.
the lowest value is 10baseT half duplex. Click ok after you made the change.

5) Click OK again. Your computer may start copying files and ask for a windows cd. Give
the computer whatever it asks for. It will then ask you to reboot the computer.
Say "yes" to a reboot.

6) When the system is completely back at the desktop, click on Start, Run, then type in
"command". This will open an MS-DOS prompt. At the prompt, type in
"ping 192.168.1.1" If you get a "Reply from...", then exit out of the MS-DOS
prompt, and start the flash upgrade. If you get a "Request time out" or
"Destination host unreachable" then go to step 7b.

7a) When the flash is completed, go back to IP ADDRESS as described in step 3, and change
your ip address back to "obtain an ip address automatically" or whatever settings
you had originally working with the router.

7b) Connect the computer directly to your broadband modem using the same network card and
cables you've been using in this procedure. Set the computer up for internet access
according to your internet service provider's required configuration settings. If
you gain internet access, then call Linksys for a possible RMA or further instructions.
If you DO NOT gain internet access, then call your ISP or network card manufacturer.

If you can see this, you have WAY TOO much time on your hand. Or you're a mod going through my sig. But if you do, copy and past this in your sig.

Yeah, it's not uncommon for routers to have some sort of failsafe. I mean basically every router that's compatible with DD-WRT can be flashed through TFTP during it's boot process. There's a second or two where the router will accept new images, so this is the window if you happen to "brick" it
