Thunderstorm Tianguangmao routers are always burned. Only after burning one set do you understand that thunder comes in through these three openings.
The lightning strike on the modem router during thunderstorms isn't mystical; it's induced lightning running through power lines, outdoor network cables, and leather cord reinforcement cores into the house. I burned a whole set of equipment before I figured out lightning protection power strips, grounding, and network cable lightning protectors. If the optical modem breaks, you can actually get a free replacement from the carrier....

NAS hard disk ext4 or Btrfs, two options for installing Feiniu are given for you.
when installing Feiniu or Synology to initialize storage, you always choose ext4 or Btrfs. My first device only checked late at night before I dared to confirm. Clearly explain the differences between snapshot, verification, and compression, and attach my two options: main drive and download drive. Just copy the homework. ...

Whether to install 100M, 300M or Gigabit broadband, you won’t have to worry about it after calculating the three accounts.
If you get pushed to install broadband, don't rush to pay for gigabits. I've tried 100 Mbps, 300 Mbps, and gigabit all once. Calculated by headcount, checking device links, and checking uplink bandwidth—three separate accounts: a family of three with 300 megabytes is just a dessert package—only two types of people actually use gigabits....

The NAS was so noisy in the bedroom that I couldn't sleep. The shock-absorbing fan actually dropped the sound by 9 decibels.
Keeping a NAS in the bedroom and making it hard to sleep? First, lie down and listen carefully—whether it's a fan or hard drive path-seeking, or resonance—three types of resonance and three treatment methods. I swapped my second-hand Galaxy drive for Cool Wolf, screwed over silicone shock absorbers, and set the fan to mute. In actual tests, the phone dropped from 42 decibels to 33 decibels, with no compromises on disc or temperature—just copy it....

Record of a car overturning after a network cable was pulled for 130 meters: It’s really not possible to go more than 100 meters
What is the maximum length of a network cable that can be stretched in meters? 100 meters is a hard standard written into IEEE 802.3 standards. I ran 130 meters of copper-clad aluminum wire for yard surveillance and it completely failed—slowing down, losing packets, and losing wires took up all the issues. This article clearly explains why it's 100 meters, how to shorten the cable distance, and the two remedial routes after exceeding it: switch relay and fiber optic transceiver....

NAS with UPS: RAID rebuild 62% trip, automatic shutdown, don’t forget to set
Should NAS be paired with a UPS? My RAID rebuilt to 62% and the gate tripped that night—11 hours of waiting were wasted. This article clearly explains how to calculate power, why USB communication ports are lifeline, how to set up three Synology hooks, and how to set Feiniu TIMEOUT. Just copy it and it will automatically shut down the power and safely shut down....

Only 4 of the 8 lights on the line tester are on. Use the dichotomy method to find the breakpoint of the network cable that was bitten by mice in the wall.
The desktop computer in the study was stuck at 93 Mbps, and after checking around, I found that the network cable inside the wall had been chewed off by a rat. This article describes how I used a wire gauge to read the light and determine which cores were broken, how to cut the break point area in half using the binary method, and how to align the three modification methods of wire replacement, wire junction, and exposed wire trough accordingly. Finally, I included the retest negotiation rate and three preventive actions....

The relay is responsible for the slowness of Synology QuickConnect. After understanding the principle, we compared it with the actual test of DDNS.
When you're out and connecting to Synology at home, QuickConnect just won't speed up? I tested the entire process from 3MB/s to 10MB/s, explaining the relay principle, how to determine which path to take, and which choice to choose between DDNS....

Only after living in two buildings can I understand that broadband in residential areas and urban villages is cheap during the evening rush hour.
Renting for convenience: using the landlord's broadband, 30 yuan a month, 90 Mbps speed test at dawn, only 20 Mbps left at night. After living in two buildings, I got a thorough understanding of the community's broadband and the self-built urban village network: how to predict in advance, which tasks can't be done, and in what order to do self-rescue—all the numbers are here....

NAS shared folders allow everyone to open an independent account so no one deletes things by mistake.
The whole family shared one admin account, and my dad just dragged and removed his daughter's photos from three years ago. I set up an independent account for each person, with three directories in the public zone, private zone, and read-only zone, plus a permission matrix. The specific setup paths for Synology and Feiniu are all written here....
