ASUS ROG Strix GS-AX5400 Review

"My dad said you are really smart," my friend said as we were all hanging out as a group. "He appreciates your knowledge and the way you present information." I was about to respond with a thanks, but not before another friend jumped in, referring to me. "He does not need any more validation. He already thinks he is smart and he does not need anyone to tell him that. It just fuels his ego at this point." Now, while I would like to believe I am reasonably intelligent and I am happy with where I am today, I try my best -- my friends, in at least a tongue-in-cheek manner, may disagree -- to not come off as having a real ego. That said, I would like to make the argument that no matter what one person's professional, academic, and social acceptance is, most will appreciate at least some validation from others. For many years, ASUS routers are well-regarded by general consumers and enthusiasts alike. I bought an ASUS RT-AC68U seven years ago, and even to now I still use it as an essential component of my home network. It delivers solid performance for the standard it was built for, had absolutely zero reliability issues over the years, and has all the features I have ever needed thanks to its DD-WRT support. In my opinion, ASUS' solid reputation for Wi-Fi routers is well-deserved, and today we will take a look at one of their latest models, the ROG Strix GS-AX5400. The ROG Strix GS-AX5400, as its name suggests, is a midrange gaming-focused AX5400 Wi-Fi router. Is this another excellent product from the company, and do they need more validation given its already excellent reputation? Read on to find out!

Our review unit of the ASUS ROG Strix GS-AX5400 Wi-Fi router came in a large brown corrugated cardboard box from the company's American offices in Newark, California, USA. Everything arrived in excellent condition to us here in Calgary, Alberta for our review today using the FedEx International Priority. The box also contained many other products, including the ROG Strix Scope NX TKL Moonlight White, ROG Strix Scope Impact II Moonlight White, ROG Strix Go Core Moonlight White, ROG Cetra II Core Moonlight White, and ZenWiFi XD6, which my colleagues and I will cover.

ASUS sent us their ROG Strix GS-AX5400 router in retail packaging. The design is recognizably ASUS ROG with a predominantly black and red color scheme to accentuate its gaming theme, which you can see in our photo above. In the middle, you will find a top three-quarters view of the ASUS ROG Strix GS-AX5400 router occupying some prime real estate. The ROG logo drawn in lighting effects fills the background behind the photo of the router. The product name and description, the latter being "WiFi 6 Dual-Band Gaming Router", is printed adjacent to the product image. Along the bottom is an array of four icons providing some highlights of this product, which is its Mobile Game Mode, Gaming Port, Easy Port Forwarding, and ASUS AURA RGB. ASUS's logo is placed at the bottom left corner, while the Republic of Gamers logo is at the top left. The remaining sides of the box has more feature highlights and specifications.
