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....

How to restore a Xiaomi router to factory settings? Hold the pin for 5 seconds and the light turns orange. If you're selling second-hand, don't rush to reset it yet
There are two ways to restore a Xiaomi router to factory settings: enter 192.168.31.1 and click on the backend, or hold the SIM ejector against the reset button for 5 seconds and wait for the light to turn orange. Before restoring, remember to write down your broadband account and WiFi password. For second-hand ones, you need to unbind and reset them at Mijia. If you reverse, you'll end up with a tail....

How to wire a network cable crystal connector? The T568B cable is enough; I scrapped six to understand the difference between four and eight cores
Cable cable connectors yourself, and only the T568B cable is enough. I wrote down all the tool logs for crimping pliers, crystal heads, line testers, the eight-step crimping process, and the four cores that only 100MB and 8 cores are gigabit, along with five troubleshooting methods for crimping failures....

How do you set a router to restart at a timer? Five brands, five names. I spent the whole night searching for the Mercury one hidden in the "automatic cleaning" section
If the router lags and disconnects after prolonged use, setting a scheduled restart can extend its life. But the five brands have different names for this feature: Mercury is called Auto Cleanup, while Asus is hidden in the mobile app. I have written down the backend paths, restart timing, and side effects of each brand all at once....

How to enable IPv6 on a Mercury router? The switch is hidden deep inside the melogin.cn, and after turning it on, connecting remotely to the NAS is really convenient
Complete process for enabling IPv6 on a Mercury router: Go melogin.cn the backend, go to the network parameters, select IPv6 switch, set the internet access mode to automatic, save and reboot, and verify with test-ipv6.com. The biggest change after enabling remote connection to NAS is that you no longer need to use internal network travers. I've also encountered the same issues with optical modem router mode and firewall....

How to distinguish between telecom optical modems, gigabit ports, and hundred-megabit ports? Gigabit broadband speed is 93 Mbps, so it's almost certainly the wrong plug
Gigabit broadband speed test is only 93 Mbps? Don't rush to criticize the carrier; most likely the network cable is plugged into the 100Mbps port of the optical modem. Check the screen print, check the backend for negotiated speed, check the computer connection speed—three ways to identify ports, include a four-core network cable slot and a free gigabit modem replacement....

Will NAS be targeted by ransomware? 3,600 QNAP units were encrypted overnight, and I put three gates on this one at home
NAS really can be targeted by ransomware—DeadBolt encrypted 3,600 QNAP devices overnight. Explain clearly how viruses get in and why RAID can't be saved, then hand over the three gates I use at home—snapshots, one-way backup, and offline drives—as they are....

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....

How to check who is freeloading on a Xiaomi router? A new device notification popped up in the Mi Home app, and I pulled out an unfamiliar phone
It's not hard to check for WiFi on a Xiaomi router. The 192.168.31.1 homepage has a device list, and the Mi Home app also provides new device access reminders. Three tricks to recognize unfamiliar devices, the difference between banning internet access and blacklisting, and the pitfalls of random MACs accidentally hit by whitelist—I tested them AX3000T and just clicked them accordingly....

How is the rural self-built housing network planned? Five cables were embedded during construction, and WiFi is maxed out on the three floors
When building rural self-built houses, embedding network cables together saves ten times the effort compared to remedial them after moving in. Five points on a three-story building, actual measurement of cast-in-place floor slab attenuation, fiber optic access to homes, and how to maintain yard surveillance—I'll go through them in the order I built my own house....
