    T-Mobile ASUS TM-AC1900 (RT-AC68U variant) gets WAN IP and can ping Internet but connected WiFi clients indicate no Internet?

    Bought a used TM-AC1900 router off Craigslist to replace my less powerful router that's been used with a Netgear modem for Xfinity Internet. Router's firmware is 3.0.0.4.376_3108, i.e., *not* flashed with ASUS RT-AC68U or other compatible 3rd party firmware and not ready to do that at this...

    TM-AC1900 upgraded to RT-AC68U unable to upgrade past 384.15

    TM-AC1900 as AImesh node?

    Apologies if this has already been answered (I did Google). Can I use a converted TM-AC1900 as an AImesh node with a Merlin master router (either a true AC68, AC86U, or AX86U) without technical problems? (I know the deal with the TM, but I need to exhaust my options with what I have before I...

    A Fine Mesh I'd Like To Be In (RT-AC86U)

    I currently have (4) T-Mobile TM-AC1900 routers all connected by ethernet Cat6. I've had these old routers for years and love them. They give me the coverage and speed I want and have not given me any trouble. I have given each router it's own SSID so that I can tell which one to use in various...

    Problem setting up AIMESH with AC68U and TM-AC1900

    Hi! Hoping someone can help me solve this puzzle. I have an ASUS RT-AC68U, with the latest firmware installed (3.0.0.4.385_10000 ). I also acquired a TM-AC1900, which I successfully re-flashed into the same (latest) firmware as my AC68U. The TM box seems to be doing great, but...when I...

    RT-AC68U dual WAN showing "cold-standby" and didn't fail over

    I thought I set up my dual wan properly, but last night when the primary WAN went down, the router didn't fail over. On checking, I noticed it was reporting "cold-standby": https://www.dropbox.com/s/0h7casz1co1ic38/Screenshot 2018-12-27 10.15.54.png?dl=0 Here are the dual-wan settings...

    WiFi Performance Issues With RT-AC68U

    I've been having endless trouble with a TM-AC1900 router that I got on sale from T Mobile a couple months ago and converted to an RT-AC68U. Ever since I've had it, I've been resetting it at least once every one or two weeks and switching between custom firmware builds including Merlin...

    No Rescue Mode (Semi Solved)

    Hello all, I've been working on trying to update my TM-AC1900 router to the latest Merlin for hours now with much frustration. I also woke up to another issue but more on that after a little back story. I bought this router a couple of months ago and have already flashed it to Merlin 380.68_4...

    [TM-AC1900] Upgrading from 376.49 to anything else

    I've been quite remiss in maintaining newer f/w on this router, and when I tried recently to go to 380, it failed. I did some digging and found out that I needed to get to 378.55 first for a new flash layout? But that also fails with the same error: "Firmware upgrade unsuccessful. It may result...

    Hi all, Just got a new TM-AC1900 a few days ago and new to all of this. I have been stuck with this problem for a few days now. Problem: I was in the process of flashing my TM-AC1900 to Asus RT-AC68U firmware when it stopped. When I next powered it up, there were solid lights on WAN and all...

    TM-AC1900 Backend

    In mid-June of this year, I attempted to login to the (non-internet facing) management UI of my TM-AC1900 and my pw wasn't working. I took the router offline, checked out my box, which seems to be fine. The next morning, I turned on the router (not connected to internet) and noticed that my two...

    ASUS RT-N68U / TM-AC1900 WAN Drops Intermittently

    I've seen a couple of old threads about this, but I'm pretty stumped regarding the WAN drops I've had with my TM-AC1900. It was working fine on stock T-Mobile firmware for 1.5 years until just a few weeks ago, where the WAN kept dropping, usually 2-3 times a day every 6-8 hours or so. Firmware...

    How to check if my router UPnP is working

    I have a Asus TM-AC1900 and I can't get UPnP to work - it's enabled on the settings page, and the logs don't show any errors. I use some programs (or devices like XBox) that are supposed to open ports but they're not being opened. How can I troubleshoot this? The router is T-Mobile branded and...

    TM-AC1900 router -- seems bricked but didn't do anything to it!

    Hi! I have two of these routers. One was connected and in use. While it was connected, I decided to try flashing the OTHER one to an RT-AC68U using the instructions that are easy to find on this site. It took some time, but I was successful. However, and this seems too weird to be concidental...
