I have been running dd-wrt firmware on my Linksys wrt600n for awhile now however I have always had some issues. I had finally had the configuration to where the issues were minimal however it has never been perfect. I decided since it had been a couple months it was time to try a newer build from the site. I upgraded and things got a lot worse in terms of wireless on the 2.4 GHz channel so I did a ton of troubleshooting and read a lot of posts semi related to my problems with the 600N on the dd-wrt forum. During the reading I learned a lot about the proper way to flash the firmware and I wanted to share my findings here.
First off when you upgrade the firmware you are supposed to do a hard reset before the firmware upgrade and after the firmware upgrade. A hard reset should be done following the below directions.
**NOTE** Hold the reset button in during this entire process
- First 30 Seconds: While the router is plugged in wait 30 seconds.
- Second 30 Seconds: Unplug the router but again make sure to continue holding the reset button in.
- Third 30 Seconds: Plug the router back in and wait the entire 30 seconds.
The entire process takes 90 seconds and the entire time you have had the reset button pressed.
So now moving on to the actual firmware update. You can find the latest and greatest builds on the dd-wrt site for the Linksys WRT600N here. I would suggest reading on the forums for versions that others have been successful with. Currently I am running the firmware that is from 03/03/09 and so far it seems to be running better than ever.
Move forward with upgrading the firmware via the routers GUI interface. I would have the router set to factory defaults during the upgrade process even though there will be another hard reset performed after the upgrade. Once the router is done with the upgrade it is suggested to wait at least a couple minutes before performing the second hard reset because the router could still be in the process of writing to the NVRAM. Once you have waited 5 to 10 minutes perform another hard reset.
Now configure the router the way that you want it to be set up. One thing I did not find on the forums or in any documentation that I overlooked the first couple time was the fact that some settings after the hard reset seem to not be on the recommended settings. The major one that I located that seems to have caused major issues with the 2.4 GHz channel was After Burner being turned on. I was seeing serious delay over the 2.4 GHz wireless channel and once I turned this off things started working a lot better. The After Burner setting is under “Wireless >> WLO-Advanced Sett.” configuration page. It is located near the bottom right below “TX Power”. I never had any problems with the 5.6GHz channel though the After Burner setting was set to Disabled after the hard reset.
Currently the 600N router is performing better than it ever has before so hopefully the above tips help someone else out.
Thank you so much this helped me decide to buy this router. I’ll be back to program it once it arrives.
Hello John,
Glad to hear it helped out. Hope you like your new router. I know you will once the dd-wrt firmware is installed.
Great summary. These steps should be incorporated into the DD-WRT Wiki at http://www.dd-wrt.com/wiki/index.php/WRT600N instead just included as a reference link at the bottom of the page.
Hello BennTech,
Wow. Thanks a lot for such a nice compliment.
I can’t update my WRT600N firmware to DD-WRT.
someone have ideal?
Hello Alexsandro,
If you want a shot at getting any feedback then you need to provide as many details as possible such as what you have tried, what errors you receive, etc. We are happy to try and help if you provide as many details as possible.
Thanks.

Hi Alex,
So, while I try update via web interface in Administration\Firmware Upgrade , I try upload this firmware in this web site http://dd-wrt.com/wiki/index.php/Linksys_WRT600N more specific this firmware ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/09-08-09-r12874/broadcom/dd-wrt.v24_mega_wrt600n.bin at 16% uploading a error exception, “Fail Firmware Upgrade” if you want a print screen I could send.
Thank you.
Hello Alexsandro,
I would try a newer version of the firmware. Download the version listed below and try that.
DD-WRT: WRT600N Firmware Download: download here
Let me know what happens with that version.
Thanks.
alex
Great, It’s work!
Thank you so much!!
Now I think, I have a problem, with this firmware my wireless band N only transfer rate at max 2MB/s, before I transfer files over 5-7MB/s rarely 9MB/s.
wl0 is 2.4GHz Channel Width 40Mhz N-Only.
wl1 is 5GHz Channel Width 40Mhz N-Only.
2 PC within WMP600N adapter, each on those interface(wl0, wl1).
What’s happen? You know?
Thank you!
Hello Alexsandro,
Sorry for the delay in response… I was on a family vacation. Anyhow check under the Advanced Wireless Settings and you should be able to adjust to your liking though I have never tested speeds with a wireless N router so I am not 100% sure of the capabilities.
If you find out what it needs to be set to please let us know so others can benefit from the information.
Thanks.

Hi Alex,
Up now, I have not any plus information about that.
I just know, the transfer rate around of 4MB/s
Very slow.
Hello Alexsandro,
What changed to make the transfer rate go from 2MB/s to 4MB/s? Sounds like you had a little success if you were able to double the previous speeds you were getting so I would be curious what changed to make the transfer speeds go up to 4MB/s even though that still is not even close to what you should be getting. When your wireless devices connect to the wireless router is the signal strength strong?
Thanks.

I am having sporadic problems with connecting at 2.4ghz. the 5ghz connections without any problems. I’ve checked and the afterburner is turned off. Any other ideas on what could be the problem?
Hello Paul,
I would assume you are getting interference outside of the actual wireless router running DD-WRT from something such as a cordless phone or something. You might try modifying the wireless channel you are using to see if that corrects the problem. If changing the channel does not resolve the issue I would recommend looking around your house to verify what you have operational that is also wireless in the house and look in detail to see if any of those devices are using the 2.4GHz band.
Hope that helps.
Thanks.

Turns out to be an issue with the wireless security. I had it on WPA Personal TKIP. Apparently that doesn’t work too well with my devices (Macbook Pro, Sony Vaio, iPhone), even though I selected TKIP on those devices. Changing it to WPA Personal AES seemed to have fixed the problem.
Hello Paul,
Awesome. Thanks for following up. This should help others running into the same issue!
Thanks.

Have been unable to download the firmware from DD-WRT site and the links from this thread do not seem to be working. Any idea what’s up with that or where I can actually find the firmware for flashing the Linksys 600N router?
