Want to flash but Trouble getting into recovery mode? Try this (worked for me).
There are a few ways to get into recovery (also known as mini-CFE) mode and not every method works for everyone: Press and hold of one or more of the buttons (WiFi, WPS, Reset) when powering the router on appears to be most common.
The theory behind this is that the router does enter the recovery mode on every boot provided the appropriate key sequence is depressed.
However that alone may not always be sufficient to flash the required downgrade or upgrade image as the case may be.
To access the recovery mode requires a web URL to be typed into a browser of a PC connected to one of the routers LAN ports. Browsers are notorious for caching previously accessed pages at the same URL. This could be on reason for failed uploads or failure to see the mini-CFE page.
One thing that could be reported to is to cycle browsers each time the mini-CFE is attempted to be accessed. For me, first Chrome worked for the downgrade. On the next instance of entering into CFE, Chrome would display the miniCFE page, and the upload would start but faily at various points never fully succeeding. Changing browsers to IE at this point helped to complete the upload.
Other suggestions would include disabling the windows and/or other firewall, antivirus, Adblocker, clear browser cache and cookies for the particular URL, disabling all other Wifi and ethernet interfaces if any on the PC that is being used other than the one directly connected to the router.
The IP address used to access the miniCFE is also something that is not easily predictable. While the logic says TMo mini CFE is at 192.168.29.1 while Asus mini-CFE is at 192.168.1.1, this has not been the case in practice. Even after clearly changing to Asus CFE it was still required to access it at 192.168.29.1
In regards to this, it may be best to do a NVRAM clear after every step of the procedure by pressing the reset button for 15 seconds on boot.

In regards to mtdwrite, even after multiple attempts, my mtdwrite appeared successful showing no errors, but the loader version was still showing 2.x instead of 1.x even after multiple reboots. I had to do a NVRAM clear in order for it to show the right loader version of 1.x.

If you're thinking about getting these for AiMesh: be aware that folks who have flashed these to stock RT-AC68Us are not able to get the AiMesh nodes to show up (myself included). Read end of thread for more:

Price is showing $49.99 now before adding to cart

Get these while they are cheap folks. The RT-AC68U (which this can be changed to via software) are true mesh devices (no external controller needed) with new AiMesh/AMAX Firmware update

Asus pulls out the game changer - New AiMesh (formerly AMAX) beta firmware (Supports the RT-AC68U [and others] which this router can be converted into via software update)
https://forums.whirlpool.net.au/archive/2660920

The only documentation available is an info/guide PDF from HERE [asuswebstorage.com], Be sure to use the latest beta firmware from HERE [snbforums.com].

Key features
1. Able to mix different models to build your home wifi system
2. Device roaming technology
3. Self-healing to ensure no interruption
4. Single WiFi SSID or separate WiFi SSID will be supported.
5. Original router features to whole system
6. Centralized setting. Set up once and apply to all models.
7. Easy to set up and manage, using a PC or a mobile device.
What is the difference between AMAS and other WiFi system?
1. If you already have an ASUS router, and you want to have WiFi system to make whole
home coverage, you don't need to buy a new WiFi system, you could buy another ASUS
router to form an AMAS system. And you can choose different models base on your
need.
2. Unbeatable WiFi coverage, two AMAS nodes could cover up to 80 % kinds of house
layout in north America.
3. Just the way you are, all advanced router features will not be removed by enabling
AMAS. Do you still want to spend extra money for those WiFi systems without advanced
networking features?
Before you try
1. Find two RT-AC68U (Series models) or RT-AC1900P or RT-AC86U. More than two is
welcomed as well.
2. If you already have one as main router, you can update that one via web GUI directly,
and then you can setup another one as secondary mesh router.
-----------------------------------------------------------------------------------------------------
This is T-mobile Version re-branded Asus RT-AC68U (likely has 800mhz dual-core CPU) .
Don't confuse with Asus AC-1900 (1400Mhz dual-core CPU), it has slight differences with different CPU




T-Mobile provides firmware update for the latest Krack wifi vulnerability:

It works fine, especially while walking and streaming, given that the media is buffered already. However if you are playing on your mobile phone, say Clash of Clans, you might disconnect.
But other than that, no one at home has complained about the new setup. They complained more when there was no AP and signal quality was bad. The transfer between APs is immediate.

When I set it up, I made a note of the MAC address on the router that was going to be turned into an AP. Hooked up the secondary router to the main via LAN port.

Went into Administration> System Mode and chose AP Mode (on that 2nd router). I put in the same wireless SSID and password as main router.
On the main router, went to LAN> DHCP Server and enabled a manually assigned IP address.
Since the main router in my home is 10.0.0.1. the AP was set to 10.0.0.2
Made sure to have DHCP leases start from 10.0.0.4 (never know if I might need the 3 spot).
Reboot AP twice.

Once that simple part was done, now I needed to set the Roaming Assistant on. So a measuring of the signal was next.

I used a phone app instead of a computer program, given that computers have a better wireless antenna as where mobile devices struggle more. Though if it's mainly computers in your home, you can use iSSIDer for Windows or NetSpot for macOS

On Android I used "Wifi Analyzer" by Farpoc, there is also a adfree version at no cost by another developer (VREM), app is "WiFiAnalyzer".
I opted for the Farpoc version because it clusters my SSIDs neatly but both apps are nearly identical with the same features.
There was no iOS app that I could find for free.

So... I stood around but not too near where the router is located (but FAR enough from the AP), checked the dBm level of the AP via the app. It was hovering around -64 which in my case was too low (lower means better signal strength) given that I would have some instability if it went upwards to or past -70s if I walked farther away and the I would still be "chained" to the AP. And no one wants to be connected to some fluctuating signal.
I lowered the Power Transmit under Wireless> Professional and kept playing with it until I got something like -78 dBm which is bad and that's what I wanted.

Now that I had found that, in the same Professional tab, enable Roaming Assistant, the default and lowest setting is -70 dBm
You will need to to do the power transmit and roaming assist for both 2.4 GHz and 5Ghz. Once set, do this procedure for the AP.
If you are still having issues with the signal being too high, you can turn the antennas around and lower them one level down and play again with the transmit power.

Just to note, you can use the WAN port on the Access Point, it will act as a spare LAN port if you need it.
Don't manually set the wireless channels on the AP, you don't want interference with the Router. And you can have both devices on the same floor, I just chose to have it on separate floors is all.

Attached is an image, obviously it is not to scale, it's just for reference so you get an idea,

I got this yesterday for 54.99 (Same seller and link from amazon) - it does have 1GHz Dual Core CPU. Took me 30 minutes to flash it with RT-AC68U firmware.

The proper way to control the behavior would be to increase the minimum bitrate that the AP requires the clients to maintain. For example, you'd only want it to accept, say, client rates of 100mbps or higher. Anything less it would drop the client and the client would be forced to reconnect to whatever the next best signal that is available. Unfortunately you can't adjust rate sets with the Apple or the Asus.

Your best bet is to ditch them both and get equipment that is designed to work together and seamlessly hand off clients between APs when better signal is available in other areas. You can do this with almost any enterprise grade equipment using 802.11r features (the cheapest probably being Ubiquiti UniFi APs), but the easiest way to go is to use one of the many multi-router WiFi mesh systems out now (Amplifi HD, Orbi, Eero, etc).

currently running one of these on lower level of house and an Airport Extreme as access point on upper level, all same SSID....I think my devices stay stuck and attached to the router when I move from one floor to another.....would replacing my Airport extreme with another identical router give me better performance in this area? I want the device to release from the upstairs router and attach to downstairs once I go downstairs and vice versa...what do you think?

I'm a little confused - in the description of the item at the link provided, it states, "1GHz Dual-core CPU enables smart multitasking by dedicating separate lanes for Wifi and USB data." I don't follow this closely enough to say for certain, but I thought the T-Mobile version was 800 MHz, just like the original RT-AC68U.

The following documentation also lists the T-Mobile version has having an 800MHz CPU: https://wikidevi.com/wiki/ASUS_TM-AC1900

Target doesn't have ASUS AC-1900.

Doesn't seem that exciting of a deal since regular price has been $60 on Amazon for the past month and a half or more.

I just bought this new from an Amazon seller for $79.xx a few weeks ago (think I'm still within the 30 day return window). Wondering if it'd be worth it to return it and get this refurb to gain the 90+ day warranty?

If it's the newer revision with the 1.0Ghz dual core does that mean it also has better shielding for the USB3 port which caused interference on the first revision?

Has anyone received it and actually confirmed it has the 1GHz dual core in it and is it worth upgrading from the 800MHz?
