Yeah the forum topic got deleted for whatever reason. A lot of information was in that thread, a lot of people are posting WNR2000v3 related threads now. Here's some info in one place to help y'all:
Prior to flashing, do the normal steps below:
Reset your v3 to default settings
Plug in an Ethernet cable in one of the LAN ports
Set a static IP on your NIC
Stuff that's useful you know. Because frankly the WNR2000v3 is a bastard child router. Blame Netgear not DD-WRT.
Build 18777 is the latest build able to be flashed for the v3:
BEFORE you do flash anything however. Its important to note that you cannot flash any DD-WRT build that is greater than 18777, this is due to the flash size, any DD-WRT build after this point won't fit, its too big. END OF.
But the router database says 26101?
Simply put the router database is wrong. It has a tendency to recommend builds that are either not suitable or inaccurate, and it certainly doesn't take into account the flash space issue with the WNR2000v3.
What is the flash space issue?
Its common knowledge that Netgear parition a lot of their routers flash space in such a away that actually makes the flash space a bit less than its advertised. In this case the WNR2000v3 is advertised as 4 MB but in fact is roughly 3.5 MB. Any builds after 18777 are great than 3.5 MB and hence don't fit.
Netgear have been up to no good, silently patching their firmware with checks for DD-WRT:
It is also important to note that if you have been updating the official Netgear firmware on your WNR2000v3 recently, chances are your unit has been patched to stop DD-WRT from being flashed onto your device. Any attempt to flash DD-WRT will be detected thanks to Netgear's checks in the patch. Woo hoo...
To resolve this, you'll actually need to downgrade the official Netgear firmware prior to doing anything. Downgrading to an older firmware version will allow you to be on firmware that doesn't have the patch in place that blocks the flashing of the initial .img file (Discussed further below). This involves using recovery mode by either connecting to your WNR2000v3 via serial cable or doing a blind TFTP transfer. This page explains the process:
Go with either version 1.0 or 1.1 to make sure you avoid the patch.
Flashing (if everything above has been read carefully and dealt with, if required)
In order to get DD-WRT on the WNR2000v3 you must first flash the .img file if your router has the official Netgear firmware on it. This will be apparent if this is your first time flashing anything not Netgear.
Grab the latest build that can be flashed to the WNR2000v3 here:
You will notice there are two .img files. One ending with NA and the other WW and finally a webflash.bin (more on that later)
NA.img = North America
WW.img = The rest of the world
Flash the file appropriate to your units origin
Navigate to the firmware update utility within the Netgear web interface at 192.168.1.1. Select the appropriate .img file and start the upgrade. Don't touch the router for about 5 mins.
If this went OK, you'll see the DD-WRT interface, rather than the Netgear.
What to do if it failed?
If your router:
a) Accepted the .img but then bricked
- Your going to need recovery mode via TFTP or Serial. See the link above
b) Refused to even start the upgrade process.
- You've likely got a newer version of the WNR2000v3 firmware that's patched to check for non Netgear firmware. See the info further up this thread.
Either way you'll now need recovery mode to save your ass, again see the info towards the beginning of this post
Great, but your not done yet. Now that you've flashed the .img file, you now need to flash the .bin as the .img is just a small subset of DD-WRT. The webflash.bin is the file to put DD-WRT on your WNR2000v3 properly.
Flashing the .bin
Do a 30/30/30 reset prior to flashing, set a username and password in order to access the DD-WRT interface. head over to the Firmware Upgrade page, and this time flash the webflash.bin file.
Wait 5 minutes for the process to complete.
After this time, you should get the DD-WRT interface again, which at this point you have completed the process. Do a final 30/30/30 reset and then configure your ass off.
Support for the WNR2000v3?
One word. Lacking. That's not because of DD-WRT being unwilling but simply because the WNR2000v3 isn't a great router to begin with. Its small flash space and lack of gigabit don't make it particularly great. If you have the chance. Don't get one, buy another router. _________________ James
30/30/30 doesn't work generally on the stock firmware, reset to defaults via holding in the reset button with a pin is the best way. Though if its brand new then I guess its slightly redundant here.
You'll have the default username and password on the stock firmware, use those to get into it.
Remember if you've got a newer unit, chances are its probably patched, you'll need to downgrade the firmware first, see the info in my post above.
After the first flash you will be asked to set a username and password before getting into the interface. You will essentially have to set this twice as you'll be 30/30/30 resetting the router a few times.
Functionality wise, the LAN ports work fine. The wireless repeating functions are iffy. Repeater Bridge works by following the Wiki instructions, but for the WNR2000v3 you'll need to enable MAC Address Cloning to resolve a bug that causes the MAC Addresses to be random all the time.
WDS, I have no idea if it works, never tried. _________________ James
Yes, the downgrade step being dependant on if you've got the firmware with the patch.
You'll know when you try and flash the .img file. If it accepts it, you can ignore those steps. If the upgrade refuses to even start the process you've got the newer Netgear firmware and you'll need to downgrade
There is no harm in flashing the .img straight away, your v3 won't brick if you do have newer Netgear firmware, it will simply refuse to upgrade.
Though it is safer to potentially downgrade to a older version, as there have been reports of bricks.
The rest of the process is correct. _________________ James
That would be logical wouldn't it? However the flash space available within the WNR2000v3 is actually about 3.5 MB rather than 4 MB. This is because the way Netgear partitions the flash space means there actually a loss of about 0.4 MB. This isn't just the case with WNR2000v3 a lot of other Netgear routers have the same partitioning.
The router database isn't accurate, but is misleading. _________________ James
