Linksys WRT1900ACS – The Old Linksys Blue DD-WRT Router Returns with Wireless-AC Overhaul

(Editor’s Note: This Linksys WRT1900ACS DD-WRT FlashRouter is now full supported with DD-WRT and officially available for purchase!)

Even those of us who spent the aughts being technologically illiterate can remember that old blue Linksys router. Computers may not have been as omnipresent as they are today, but lord knows we remember seeing our fair share of blue Linksys routers. Look at the image above and tell us it doesn’t look familiar. It was the beginning of broadband Internet as we know it.

That’s the WRT54G, a mostly phased out Linksys router and replaced by newer, sleeker models over the years. The WRT54G was first released in December 2002. While the amount of innovation in the world of technology has been almost immeasurable in the past twelve years, looking back at the base-point items that opened the door for progress shows just how intense this growth actually is.

The WRT54G was the first router to truly spark innovation in the open-source community for router lovers.  The birth of DD-WRT firmware is tied directly to the WRT54G in its early era.

But after Cisco sold their Linksys home networking to division to Belkin, it looks like this old blue mainstay may see its time in the sun again with the Linksys WRT1900ACS DD-WRT. The re-release of “retro” tech products is a great way for fans to remember the history of these innovations like Chevy revamping and energizing the Camaro, and a reminder of just how rooted elements like wireless routers have become in our everyday computer usage since the good old days.

Linksys WRT1900AC – DD-WRT or Tomato?

Yup, Belkin’s getting a little nostalgic. There’s a new WRT54G in town, and it’s been updated in a pretty massive way.

More accurately, Belkin unveiled the Linksys WRT1900AC at CES 2014 to ebullient, jubilant crowds and effusive geeks. The WRT1900AC is cosmetically designed in tribute to the WRT54G what they call “the best-selling router of all time.” No more E or EA series stuff. Back to the WRT basics, we say! Even though, it’s does feel weird to get nostalgic about a device that is a little over a decade old.

Since the WRT1900ACS is a brand new device, it’s packed with all of the latest router hardware specs to revamp the dormant Linksys brand as a serious competitor and innovator in the SOHO market (where they have lost much cache to Asus and Netgear). And boy, they didn’t seem to cut any corners here.

The Powerful Specs of the Linksys WRT1900ACS

Across the board, the WRT1900ACS is like no Linksys router until this point.

Antennas: Designed with a purpose for functionality and beauty, while boasting next-gen Wireless-AC capability, the WRT1900AC is capable of offering some of the highest speeds available from is impressive 4 omni-directional antennas. It is pretty exciting to tweakers and Linksys lovers to see those iconic external antennas come back into the fold.

Processor/RAM-Flash:  The WRT1900ACS promises an unmatched dual-core 1.6GHz processor, 256MB/128MB of DDR3 RAM/Flash memory.

USB 3.0 Port: The USB 3.0 port is an exciting add-on to this retro looking router, with a Super Speed transfer (USB 3.0 is 10x faster with transfer speeds of up up to 5Gbp/s) to make tasks like moving video files fluidly to networked hard drives much more efficient.

When the original blue bomber was unleashed, USB was not included and probably not even thought of being a network based activity. Now this functionality are almost required for any high performing wireless gateway. But this USB 3.0 introduction is a game changer when it comes to network sharing.

Open-Source Firmware (DD-WRT, Tomato, OpenWRT) Support: Linksys also says the device will support open-source firmwares like DD-WRT, Tomato, and Open WRT, which is exciting for those in the open-source community (us included).

The return of this classic router is very exciting, especially concerning the fact that it’s been formidably updated.

Until then, we’ve got plenty of intimidating devices of our own, including several Wireless-AC routers that have been flying off the shelves at FlashRouters headquarters. Around here, all of our devices are flashed with either DD-WRT or TomatoUSB firmware, so combine the advanced functionality of those replacement firmwares with the speeds of Wireless-AC, and you’ve got routers that are stronger, faster, and more versatile than any others on the market.

Enter the Netgear Nighthawk R7000 DD-WRT, which has quickly jumped up our best-selling routers list. Find out more about the power and dizzying speeds of this amazing device. With equivalent specs to the WRT1900ACS but full open-source support, the Nighthawk is the superhero of high-end wireless networking.

      I wish there was more but it doesn’t seem to be progressing much. With linksys, we are hesitant when they announce something as fact like DD-WRT support without asking the DD-WRT community.
