Flashing Netgear WNR2000 (v2) with DD-WRT

>> Friday, January 07, 2011

Finally I got hold of a Netgear WNR2000 (v2) router and changed it to act as a repeater bridge . I can now connect my desktop in a different room to the main wireless modem. Even though this particular router has the capability to act as a wireless client and/or a repeater bridge, the factory firmware doesn’t allow you to do it. Flashing the router with dd-wrt will enable you to do that and also opens up lots of other possibilities. Once its done its kind of trivial, but there were little or no instructions available on the web to do that.

(Disclaimer: Fortunately I didn’t get any of the complications mentioned in some of the forums. I’m writing this for my own benefit too so that I can refer back to this later. You are at your own risk in following these guidelines and I’m in no-way can not be hold responsible. Also, if things go wrong you will end up bricking your router, yes I’m serious.
If there are any complications, please contact dd-wrt forum. I have little or no knowledge to fix those complicated errors.)

Step 1: Making Sure
Make sure your WNR2000 router is v2 and not v1. Only v2 is supported by dd-wrt at this time. The version is marked on the router itself. But at the store, if the outside box doesn’t explicitly mention it, check whether the serial number is starting with 23B or 23D. If that’s the case, then its a v2 router. Flashing a v1 router (if it works can brick the router)

Step 2: Getting Firmware
To download firmware needed go here and pick the file that ends with “WNR2000v2.chk”. When I was writing this the latest available version can be download from this link.

Before the next set of steps, go to this link and read all the warnings and guidelines found in section 1 and 2.

(These instructions are copied from here, but adapted to suit WNR2000 router)

Step 3: Reset The Router
Do a hard 30/30/30 reset of the router.

Step 4: Login to the Router
Connect your router to your computer, using a Ethernet cable. Make sure your computer is not connected to any other network. Open up a browser and go to http://192.168.1.1. Login with root as the username and admin as the password. Just glance through the settings just to make sure everything is working fine.

Step 5: Upload the Firmware

  1. On the router page click on Maintenance –> Router Upgrade. Remove the check on “Check for New Version Upon Log-in”.
  2. Click on “Choose File” and point to the file you downloaded in step 2. Then click “Upload”. It will take about 2-4 minutes and DO NOT interrupt this process.
  3. At the end of the above process, if everything is successful and if you refresh the router page you will see the new DD-WRT page. Make sure to give a new username and password. At this point, reset or restart the router and after that you are done.

Now you can make your router an access point, repeater bridge, wireless client or so much more by following the instructions here.

The WNR2000 default username is not "root" but is "admin" so why use "root"?

@yusufadam the default username is "root" because that's the administrator account for linux operating systems.

This guide worked for me on the netgear WRN200v2. The problem I had initially was going straight to the current version as of this writing:
From ddwrt supported device download list:
K26 mini dd-wrt.v24-21061_NEWD-2_K2.6_mini.bin
---
What worked was the version listed in the ddwrt wiki and this article written by Eran:
v.24 SP2 - build 14536 - 20100531

After installing v14536 the new version (21061) upgraded just fine.
