Guide pour le support ASUS Router
This article outlines my current network configuration. I’m familiar with networking concepts but haven’t dealt with anything advanced. Over the last few months, I’ve acquired an Asus ZenWifi Pro ET 12 dual-band router to set up a mesh network. My home spans around 4,000 square feet and requires more than one router to cover effectively. I currently pay for over 500 downloads and about 20 uploads from Armstrong, though fiber service isn’t available in my area yet. The routers are linked via Ethernet cables because I treat the secondary node like a switch, mainly due to a smart TV and an Armstrong streaming box that I prefer to hardwire.
The challenges I face include inconsistent speeds and high latency when multiple devices are active. There are two smart TVs, several iPhones, MacBooks, and smaller Wi-Fi gadgets on the network. Two PlayStation consoles and one MacBook are the primary wired devices. When both Playstations are connected simultaneously, I experience sudden lag spikes and poor latency.
I’ve confirmed with my ISP that there aren’t any issues on their end. Earlier, when using older Asus routers, I didn’t encounter similar problems. Here’s how the setup works: the modem connects to the main ET12’s 2.5G WAN port. The ET12 then connects its 2.5G LAN to Switch A, which links to Switch B and Switch C. Switch B powers the MacBook and PlayStation, while Switch C handles the smart TV and Armstrong streaming box. Lan 1 serves as the secondary node. On my Wi-Fi, I usually manage around 200 downloads per connection.
Testing Ethernet connections across various locations showed stable performance—roughly 770 downloads and 17 uploads with minimal traffic. The modem’s speed remained consistent. With two 4K TVs streaming Top Gun in 4K and a PlayStation downloading Red Dead Redemption, other Ethernet links handled about 485Mbps and 10Mbps, which is still solid. Adding a PlayStation streaming NBA 2K24 on the same wired connection drops speeds to around 170Mbps and 6Mbps—still acceptable in my view.
When both Playstations are on and I’m streaming games like Call of Duty, buffering and lag appear only when multiple devices are active. No faulty cables or switches were found. The Asus routers include a QoS feature, but I haven’t explored it yet. On the interface, speeds are visible in real time, rarely exceeding 3Mbps. It seems that having around four devices using regular bandwidth doesn’t cause significant throttling.
I’m still trying to pinpoint the exact cause of the slowdowns. Any advice would be greatly appreciated.
