I live in a two-story home with thick brick walls and a basement. The original router placed in the living room couldn’t reach the basement or the back bedroom. I bought a second ASUS RT-AC68U and set it up as a satellite node using AiMesh. The setup was straightforward. I connected the second router via Ethernet to the main one, then accessed the AiMesh dashboard through the ASUS Router app. Within minutes, the system recognized both devices and created a unified network with a single SSID. Now, my phone and laptop automatically connect to the strongest signal—whether I’m in the kitchen, basement, or upstairs bedroom. I no longer experience dropped connections during Zoom calls or buffering when streaming from the basement. Here’s how I configured the mesh network: <ol> <li>Connected the primary router (AC68U) to the modem via Ethernet.</li> <li>Plugged the second AC68U into a power outlet near the basement, then connected it to the primary router using an Ethernet cable.</li> <li>Opened the ASUS Router app and selected “AiMesh Setup” from the dashboard.</li> <li>Followed the on-screen prompts to assign the second unit as a satellite node.</li> <li>Enabled “Auto Channel Selection” and “Band Steering” for optimal performance.</li> </ol> The key benefit is seamless roaming. When I walk from the living room to the basement, my devices switch to the nearest node without dropping the connection—something I didn’t have with my old router. <dl> <dt style="font-weight:bold;"><strong>MESH Networking</strong></dt> <dd>A system where multiple routers work together to extend Wi-Fi coverage across a large area.

I’m an avid online gamer and also work from home. My setup includes a PS5, two laptops (one for work, one for gaming), and two smartphones. During peak hours, I often have a 4K video call with my team while my son plays Fortnite on his PS5. Before the AC68U, I experienced lag spikes and audio dropouts during calls. Now, with QoS enabled, the router prioritizes my Zoom session and gaming traffic over background downloads and smart home updates. Here’s how I configured it: <ol> <li>Accessed the router’s web interface via 192.168.1.1.</li> <li>Navigated to “QoS” under the “Advanced” tab.</li> <li>Selected “Enable QoS” and set “Priority” to “High” for my laptop and PS5.</li> <li>Added specific applications: “Zoom” and “Fortnite” to the priority list.</li> <li>Set bandwidth limits for non-priority devices (e.g., smart lights, Alexa).</li> </ol> I’ve run speed tests using iPerf3 and observed that during a 4K Zoom call (10 Mbps upload), my PS5 maintained a stable 15 Mbps download with ping under 30 ms—perfect for competitive gaming. The router also supports MU-MIMO (Multi-User Multiple Input Multiple Output), which allows it to send data to multiple devices at once instead of sequentially. This reduces latency and improves overall network efficiency. <h2>Is the ASUS RT-AC68U Worth Upgrading to the Merlin Firmware?</h2> <a href="https://www.aliexpress.com/item/1005003363288295.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S52b2234e0c354258a3d9049dcc2d9d63W.jpg" alt="ASUS RT-AC68U AC1900 1900Mbps Wi-Fi 5 AiMesh For Mesh Whole Home WiFi Dual-Band Router, Upgradable Merlin System AiProtection" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;">Click the image to view the product</p> </a> Answer: Yes, upgrading to the Merlin firmware (based on ASUSWRT-Merlin) significantly enhances the router’s performance, security, and customization options, especially for advanced users.
