DDWRT can be installed on this router. If you do not need AIMesh, Latest updated DDWRT firmware (krack patched) is available for this router and runs great and has an excellent android app too for remote controlling the router.

Unfortunately, SNB now disallows discussion about converting TM-AC1900 to RT-AC68U with AiMesh [snbforums.com]. So, modding information may be a bit harder to come-by going forward. Discussion looks to have moved to Whirlpool.net.au [whirlpool.net.au].

Follow this guide: (https://www.bayareatechpros.com/ac1900-to-ac68u/) :
1) Allows flashing to RT-AC68U firmware w/ AiMesh
2) Cleans the /dev/mtd5 partition which removes a file on the TM-AC1900 that is not on a stock RT-AC68U. This currently will allow stock ASUS 384.20648 firmware to install with no rollback)
3) Enjoy your up-to-date RT-AC68U
*If you get stuck, read the comments on the bayareatechpros site, there's a wealth of information on how to get it to work*

You can flash this router to an RT-AC68U: https://www.bayareatechpros.com/ac1900-to-ac68u/. Avoid CFE 1.0.2.5 from the RT-AC68P, as the newest Asus firmwares (3.0.0.4.384.20624 and later) detect this on the TM-AC1900 and revert the mod. Instead, use CFE 1.0.2.0 US AiMesh; it was dumped from an actual RT-AC68U by user goggles99 at SNB.

Note: some routers may ship with a firmware version that allows SSH access. If you get one of these you can skip steps 5-10 of the bayareatechpros guide. To check if you have SSH available, go to Administration > System in the router interface. If your firmware permits SSH, there will be a setting to Enable SSH. If so, choose Yes then Apply. Move on to step 11.

If you only follow the bayareatechpros guide linked above, the latest ASUS firmware you can run without your mod being undone is: 3.0.0.4.384.20308 [asus.com] (AiMesh is supported in this version)

If you would like to run newer firmware (tested up to 3.0.0.4.384.20648 [asus.com] so far), then start by getting your router on 3.0.0.4.384.20308 using the bayareatechpros guide. Be sure to use CFE 1.0.2.0 US AiMesh (use the generator [pipeline.sh] by danielfeng). After you're running 3.0.0.4.384.20308, enable SSH in settings. Then, you can SSH into the router and wipe the T-Mobile certificates from the mtd5 partition. The instructions that originally existed on SNB before that forum thread was shut down [snbforums.com] are below (Credit to XVortex and rdallen at SNB for these instructions!). Once you've cleared the files out of the mtd5 partition and rebooted the router, you can flash 3.0.0.4.384.20648 using the GUI.

Code:
# Backup MTD5 (dd produces identical bin)
cat /dev/mtd5 > /jffs/mtd5_backup.bin

# Manually copy mtd5_backup.bin from router using scp or Winscp. Keep it safe on your computer for each router.

# Wipe files which identify the TM-AC1900
ln -s /sbin/rc mtd-erase
./mtd-erase -d asus
 
nvram unset fw_check && nvram commit && reboot
ASUS RT-AC68U firmware [asus.com]
It looks like ASUS no longer shows previous firmware versions there. Here are some direct links (the URL structure is pretty easy):If you are on TMobile firmware and having problems accessing the mini-CFE webserver this works.

Power off the router using the power button
Ensure a LAN cable is connecting your PC and the router's #1 LAN port (a yellow one, not the blue one)
Set your PC's IP to 192.168.29.2 (assuming the recovery mode is 192.168.29.1)
Navigate to 192.168.29.1 using your browser. Browser status will spin indicating looking for page
Press and hold the reset button while powering on
When the mini-CFE webpage appears on the browser, release the reset button

The browser status must be spinning (looking for a webpage) for this to occur. This method seemed much easier than the hit and miss of trying to go into mini-CFE webserver blindly.


"Specified time interval can not overlap." error:
After upgrading to firmware version 3.0.0.4.384.20308, if you see this error when trying to make any change on the Administration -> System page (such as enabling SSH), change the timezone to GMT (or something that doesn't require DST settings) and then make your changes.

It seems to be a router GUI bug in this version of firmware where DST start/end parameters can not be set and that cases this error.

This issue goes away once you upgrade to firmware version 3.0.0.4.384.20648 (after removing the mtd5 partition first, as mentioned above). With this firmware version, you can set the timezone with DST settings.

Note: Asus has deleted Firmware 3.0.0.4.384.20308 from their site. This is the interim Firmware used in the upgrade method mentioned above. You may still obtain this firmware from alternate websites. Confirmed that this one worked today with a TM-AC1900 that was converted to a RT-AC68U. Asus 3.0.0.4.384.20308 Firmware [softpedia.com]

Yes, ASUS is actively trying to divorce their relationship with this rebrand of the RT-AC68U. For years they just quietly ignored it while refusing to give technical and warranty support (even with their name proudly plastered all over it and in the documentation).

It was once thought that "converted" units were indistinguishable from "real" RT-AC68Us once the CFE was replaced and OEM ASUS firmware was installed. However, so far ASUS has made several unsuccessful attempts to prevent installation of their most recent firmware. They started showing up in beta releases that included the AiMesh feature. This was easily defeated in the hacking community (mostly on SNB forums) by installing the CFE taken from a "real" RT-AC68U - after patching the correct MAC address & WPS secret key.

This worked for the first couple official production releases of the new firmware (major release 3004.384.xxxxx). Converted TM-AC1900s worked fine as AiMesh components (main router and nodes) through release 384.20308.

After that the newer releases (20624 and 20648) became malicious. These were just supposed to be general bug fixes, but if it detected that the router was a former TM AC1900, it downloaded and installed TM firmware and rolled back the CFE so it couldn't be re-converted.
It took a few days to figure out how they were detecting TM routers, and a new hack was posted on the SNB forums (which was increasingly becoming hostile to TM hackers). Almost as soon as the new hack method was posted, that thread was deleted, our PM's deleted (and blocked), and a policy was posted banning discussion of TM-AC1900 conversion.
In the mean time, displaced fans of TM-AC1900s regrouped and congregated on the Whirlpool.net.au forum (no affiliation with the appliance company). A method was documented on how to unlock the rolled-back units using an old backdoor exploit. Also, the info that got the thread banned on SNB was recreated and better documented. So at this time, we can continue to install the latest ASUS firmware and avoid the malicious rollback trojan that ASUS silently embedded in release 20648.

What remains to be seen is what ASUS's next move will be. How much money and engineering resources will they expend for their next futile attempt to blacklist the TM-AC1900? At some point they will realize they can't win and for a few thousand routers (many 4-5 yrs old) it isn't worth pursuing.

I'd be concerned that some of these refurbs were returned with TM 376.3199 and a locked CFE, which would make them much more difficult to convert. You'd need to exploit a well-known security hole to install a new CFE and old firmware.

If you read above and follow the LINK he provided it takes you to Amazon.



On another note, any opinions on how this compares to the LINKSYS EA2600 router??

I ask for our router is not always reliable and wondered if this one is better AND more reliable a model...

Thank you.
