T-Mobile (AC-1900) By ASUS Wireless-AC1900 Dual-Band Gigabit Router, AiProtection with Trend Micro for Complete Network Security

This router can make a huge difference when used in a device-rich environment. I have 20+ wireless devices; an xbox, Dish network, and PCs plugged into the built-in gigabit switch, etc. All devices are sharing the internet and some devices are connecting peer-to-peer for on-LAN gaming/etc. My previous single-core Cisco router was getting overwhelmed with the traffic and producing less-than-optimal bandwidth. This dual-core 1ghz router is handling it all and providing maximum throughput. I'm just using the stock TMobile bios that came on it (didn't re-flash to ASUS) which seems very feature-rich and doesn't appear to have any tmobile-specific limitations. You can setup VPNs, usage restrictions by hour, shared storage, isolation mode, etc. Streaming movies and downloading xbox games now function at near my max internet bandwidth (I was only getting half before) and the "lag" of online games (latency) has improved noticeably according to my kids. The unit I received was brand new sealed, so I'm not certain why the other reviewers are saying it is used. Mine came from "trulythebest" and was fulfilled by Amazon. And, I now have strong signal throughout my entire 2000sqft house. Overall a great router.

I got my first AC-1900 from T-Mobile because my cell phone signal is weak at my home. We use it for making cell phone calls over internet. I love the setup on this router. Easy to configure and versatile. I have recently purchased 2 of these from Amazon to extend our Wifi signal to all of the house and garage. Excellent quality and longevity.My experience with other wifi routers has been that they normally only last a few years, then they die. I have gone through many routers over the years. The first Asus router has lasted longer and given superior service than any other router I have owned.

A $155 router for only $82, whats not to love.This router internally is the exact same hardware as the AC68U.This router will work perfectly well for the average user regardless if they use the t-mobile wifi calling or not.I have seen many people drop big money on routers to find out they paid an extra $100 for feauters they cant use. If you dont have 10+ devices on 5ghz then tri-band is irrelevenat, and most wifi chips in laptops and phones dont have MU-MIMO and have at best 866mbps speed chps.These AC1900 routers of ASUS have great range, dual core cpu, a better UI then many other firmwares and can handle a lot of devices (I have over 30 wired and wireless devices on my home router).The stock t-mobile firmware is a little restrictive vs the stock ASUS and does not upgrade as often. For the normal user this will in no way be an issue. For advanced users with higher needs there is ways to flash it to the AC68U firmeware, but word of warning it involves a lot more then just upgrading through the web gui utility.

As others have stated, my router arrived USED. Was missing items, all packaging was opened, and the router was already set up and password protected.After dusting it off and a full reset to remove the passwords locking me out of the router I was able to quickly set up the router using an LTE modem connected to the USB. Speed and Range is on par with the AirPort Extreme it replaced and I was able to ditch my crappy cable internet and use my wireless carriers unlimited data plan with a real router that covers the entire house and allows all 20 or so devices to connect reliably.The built in TimeMachine support (I have a Hard Drive connected to the other USB port) does not work with the current firmware version and T-Mobile does not seem to be worried about updating it but a quick Google search on the internet will show you how to flash the Asus firmware.

So far the router has worked flawlessly and I am getting the expected throughput and better coverage than my previous wireless N router. Comcast recently upgraded my Internet speed to 200 Mbps and my current Asus RT–N66U was maxing out at delivering about 100 Mbps. It was killing me that I had speed that I couldn’t use (at least over Wi-Fi) but I didn’t care so much that I would sink more than $100 into an upgrade for an otherwise functioning router. I chose the TM AC-1900 because, as others have said, it’s essentially identical to the Asus RT-AC68U (except for a few minor differences that frankly weren’t important to me) at a fraction of the price.I can have up to 35 devices connected to my home network at a time. This router handles the traffic perfectly with no dropped connections and utilizing the full speed of my connection (of course depending on network traffic and the capabilities of the connected device).I will add that the router I received was clearly not new. All the seals on the box were open, as were the accessory bags, and the box looked a little beaten up, though all parts were present and nothing looked worn. I can’t say whether it’s used, refurbished, or merely open-box, but it works and looks fine, so I don’t really care, given what I’m getting for the price. I do, however, agree that this should be noted in the product description (-1 star).I’d also like to offer a tip for those taking advantage of a new router to increase their Wi-Fi security. Like many people, each time I have upgraded my router over the years I simply kept the SSID and password the same to facilitate an easy transition. However, as time went on, I realized that the password I chose 8 years ago was not nearly as long and random as it should be. So, when setting up this new router I created all new network credentials, but I also set up one of the guest networks with my old credentials and gave it full network access (not “internet connection only”). This made sure everyone / everything remained connected and I could take my time distributing the new info to my family and changing the credentials on all my smart home devices, printers, media players, etc. I then simply turned off the guest network when everyone had switched over.
