I've just bought a second-hand Linksys WRT54GS (v4) with intention to put DD-WRT on it. Unfortunately, I have problem with software currently running on this device.

It has Sputnik based on firmware version 4.70.6. This version number seems like from v3 hardware version of this router. I think that before Linksys made firmware specific to the v4, the same binary was used for v4 and v3.

The problem with that old Sputnik is that I can't reflash it with another firmware. I've tried with latest Sputnik, initial DD-WRT flash (from Sputnik website) and clean Linksys firmware for v4. None of that works, flashing process just stops with error (I'm using web-based interface for flashing and done 30-30-30 reset before attempts).

Then, deep in the internet I found something that seems like a solution - somebody successfully downgraded from Sputnik v4.70.6 to clean v4.70.6 and then to v4 firmware. So why I'm writing this instead of downgrading my router software? Because it seems impossible to get that crucial Linksys firmware for WRT54GS hw v3, v4.70.6. It has been taken down from Linksys website and all links I have found are dead. The support guys claim that they don't have that file (that means "we are not authorized to give it to you" for me).

So, if some of you has this file left on hard drive, I would be very glad for sharing it. Or, if you have some other ideas on how to put DD-WRT on it, that would be also very welcome.

This question came from our site for system and network administrators.

    
Honestly it's not worth it these days, when you can get much more powerful 802.11n home routers for $20-$25. –  Michael Hampton Jul 12 '13 at 7:08
    
@MichaelHampton: I don't see why would I have to buy another device when that one fits my needs perfectly. "Buy a brand new one" is an answer that could be posted to significant amount of questions here, yet some people, me included, prefer to solve their problem in the other way. –  user1234567 Jul 12 '13 at 7:13

The question basically comes down to: who has version X of software Y for me? Maybe you should change your title accordingly. I don't know if this site is for that type of question, but you can always try. I think you will have better chance at a forum specialised in Linksys or routers. –  SPRBRN Jul 12 '13 at 7:36
    
@rxt: Good point, I changed the title. But I think that there must be other solution for this problem, I didn't have time to try flashing DD-WRT initial with TFTP yet, but there's a chance it will work. –  user1234567 Jul 12 '13 at 7:46

Issue solved. After a lot of reading I realised I made some wrong statements. The thruth is that:

  • The router had a Sputnik install based on wrong firmware version - it was for v3 hardware, not v4
  • Because of that router ignored all v4 specific upgrades.

I was able to succesfully flash DD-WRT mini generic version via Web interface and I have fully working, DD-WRT enabled router now.

And just for reference - I found a website with old firmwares! http://download.modem-help.co.uk/ has a huge archive, including files for my device.
