The USB port on the router is really not just for show. Plugging in a hard drive to become a file server, a 4G internet card as backup broadband, a hard drive as a download machine, and connecting a printer for the whole family—I've tried these four methods one by one. Which machines are worth the hassle and which are just for show? This article explains everything clearly....

Router QoS is a switch that divides data into fast and slow lanes; it doesn't increase bandwidth, only determines who goes first. If someone at home gets lagging as soon as they download FamilyMart or game ping spikes to over 200, it's most likely time to try it. However, you need to correctly fill in 85% to 90% of the measured bandwidth; if you fill in incorrectly, your whole family will see slower speed. This article clearly explains the principles, pitfalls, and the positions of various switches from different brands....

The IP address of every device in the home is automatically sent by the router's DHCP. I accidentally turned it off, but FamilyMart's WiFi is full but I can't get online. Address pool, lease, static IP—these terms are explained in one go, with three situations where you really should turn them off....

What does Router Beamforming mean? It's not about increasing power, but about focusing the signal toward your phone with multiple antennas. I tested both on and off for a week; the balcony speed differed by 60 Mbps, but the living room showed no change at all. This article explains the principle, the difference between explicit and hidden types, and how to choose a switch....

Can't find the power settings in the router backend? I tested all three levels of Xiaomi signal strength, ASUS modified the region, and OpenWrt power slider. In actual tests, wall penetration mode only increased by 3dB, and I realized the national standard has soldered the transmission power cap. If the signal is poor, the real issues to adjust are the location and channel....

What do 2x2 and 4x4 routers mean? It's not the number of antenna roots, but the number of spatial streams. Phones are almost always 2x2, and a 4x4 router is useless against a single phone. This article explains how to calculate negotiation speeds for 867, 1201, and 2402, and includes a command to check your device's current status....

How many years does a router typically last? There is no official retirement period; the retirement age for my three machines is 8 or 5 years, and they are still in service. Capacitor aging, firmware downtime, and WiFi standard iteration are the three major killers. If two of these five signal signals appear—restarts are getting more frequent and 5G is getting weaker—don't spend 50 yuan fixing them—old machines can still be replaced with APs for reuse....

What should you do if WiFi has a high packet loss rate? Teleportation in games and intermittent voice chats, but speed tests are normal—most likely due to packet loss. Using the three-band ping method to distinguish whether the issue is a WiFi band, router, or broadband outlet, with packet loss rate criteria and a fixing comparison table....

Is the router's CPU processor important? Most of the time, it really doesn't matter: forwarding is done with hardware NAT acceleration, and even a decade-old CPU can run at gigabit speed. But after flashing with plugins, enabling QoS, or running VPNs, I've experienced gigabit dropping to 380 Mbps. This article clearly explains when the CPU is slacking off and when it's risking its life, along with a comparison of three CPU levels and self-check methods....

Router flash storage and memory are often confused, and customer service even uses 16MB flash as a selling point to evade the issue. This article clearly explains how much flash storage can be installed and how much memory can be installed simultaneously. If the flash memory is insufficient, an error occurs halfway through plugin installation; if the memory is insufficient, it causes disconnections due to too many devices. By the way, I'll also offer advice on the configuration setup for a three-tier laptop....
