Folks,

I have a Linksys WRT1900AC, Version 1 router. It has been running for about a year and a half on the crappy Linksys firmware, to the same mixed results I've been reading about all around: lousy wireless range, dropped connections, etc.

Recently, I was thrilled to learn that the long-awaited DD-WRT firmware had become available, and I followed directions to download the proper DD-WRT image to convert from factory to DWRT for my 1900AC V1 router (v3.0 Beta, build 28628 initial installation image). So far, so good.

Next, I followed the standard on-line directions to install the firmware by entering the router's configuration page in Chrome on my Win 10 computer (which is connected by LAN to the router), and manually undating the firmware in "Connectivity."

But it didn't take. Specifically, the router seemed to be installing the new firmware, then asked permission to reboot, which I gave it. After a few minutes, though, it simply rebooted back into the factory firmware (version 1.1.10.167514, incidentally).

I tried reinstalling the DD-WRT image several times, but always, the router rebooted back into the factory firmware. I even tried, hard-resetting the modem back to factory, and doing the whole thing again. Still, DD-WRT simply would not load.

I'm really looking forward to using the router with DD-WRT, and am bummed I can't get it to work. Can anyone help me figure out why this is, and how to fix it? Naturally, support at Linksys (or whoever the parent company is) won't help me at all.

If further information is needed, I'm happy to supply it.

Thanks in advance,

Agreed. Get the latest Kong image downloads for your router (there are two). Then flash the FactoryToDD-WRT.img file from the LinkSys F/W update screen.

Do not attempt to flash the BIN file directly from the LinkSys F/W update screen, otherwise you will be in a world of pain!

Thank you! Thank you! I will attempt to flash the FactoryToDD-WRT.img file as soon as I get home from work. I will report back with results. Much appreciated!

Tried using Kong's firmware image, and unfortunately had the same result: after installing firmware and rebooting, router simply returned to the Linksys factory firmware setup screen - No DD-WRT.

Any other suggestions?

Thanks,

Are you running LinkSys v1.1.8 F/W? If you are running a later version, then try downgrading to v1.1.8 prior to applying DD-WRT.

I am sure that I read that this was a requirement elsewhere on this forum.

Yes, that did it! Had to downgrade to the older stock firmware. Once I did that, DD-WRT loaded right up. Thanks for your help.

Hi guys,

I know this an old post. I bought recently a wrt1900acs V2. Firmware it comes with is already v 2.0.1. Flashing an older stock firmware the router gets stuck in welcome screen and needs to be powercycled.
After Flashing ddwrt when reboots, the router keeps booting in stock firmware (same as above).
Not sure what else to try, any guidance would be appreciated.
