What does Router DHCP mean? The night I accidentally turned it off, the whole house went off the internet, and I figured out the address pool and the lease
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? I tested both the power on and off for a week; my balcony WiFi is all thanks to this
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 the router's transmission power be adjusted? After a full wall penetration test, the power ceiling is welded shut right out of the box
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 router antennas mean? The phone's speed is stuck at 867Mbps, so I have calculated the spatial flow issue clearly
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? My oldest child lasted 8 years. If two of these five aging signs appear, don't fix it
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....

How to troubleshoot WiFi with high packet loss rate? The game was lagging and the voice lines were all awkward, so I used three pings to catch the real culprit
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? After flashing, only 380 Mbps of gigabit remained. I calculated the core frequency clearly
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....

What is the difference between router flash memory and memory? The night I couldn't install the plugin while flashing OpenWrt, I completely distinguished between the two
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....

What is the difference between WPA2 and WPA3? If you enable WPA3 and old devices can't connect, choose router encryption as follows
I switched to a new router and set WPA3 for encryption, but the old laptop, camera, and Kindle all couldn't connect to the internet. This article explains the differences between WPA2 and WPA3, how to set up hybrid mode, and which households should use WPA3, along with various brand setup paths and pitfalls to avoid....

Can WiFi 5 and WiFi 6 routers be used interchangeably? Don't rush to throw away your old router—I've tested all three connection methods
After switching the main router to a WiFi 6 AX3000T, I didn't throw away the old WiFi 5 router in the cabinet. Instead, I tried using three different connection methods: direct device connection, network cable cascading as an AP, and wireless relay. Will they slow each other down? Actual test data speaks for itself. ...
