Storing one copy each for important files on the NAS locally and in a different location isn't enough. My mom's home and I live in the same city, so a whole house disaster can be handled by two units at once. Bring NutCloud into the cloud as the cloud version: the free version uploads 1GB of data per month, photo library out of reach, but losing 640MB of documents, scans, and password libraries is truly devastating, so using WebDAV to push once a day is just right. App passwords, bandwidth limiting, and file retransmission have all been handled for you....

My cousin filmed a video late at night asking if the Mercury router's light kept flashing and if it was infected, but what he was staring at was actually the data light on the WAN port. This article explains what the SYS, WAN, and LAN lights on the Mercury panel each govern: the old SYS model flashes slowly normally, the new model stays on normally. It also provides a three-layer positioning sequence for checking the lights when the network is off, so you can identify the fault segment before proceeding....

The optical modem and router have the opposite temperament: restarting the router regularly every week is maintenance, while frequent power outages actually cause damage. Every night, my mom uses a smart socket to cut off the power modem and saves energy. Over two years, she saved 17 yuan, and the price doubled when the light declined materially. This article thoroughly explains the registration process, lasers, and the correct restart posture....

If your NAS drive is full, don't rush to replace the machine. Pulling out the external hard drive and plugging it into the USB port can extend its life, but it's only suitable for storage, not for storage. I've been out of control for three months: the 3.5-inch with power supply is as stable as an old dog, the 2.5-inch bare-plugged drive drops twice every three days, and the corrugated drive drops to over 20MB for large files. The power supply, format, disconnection pits, and the numbering table have all been arranged for you....

If the webpage won't open, first blame the DNS, but what exactly is DNS doing? I ran the entire parsing process using nslookup: recursive route asking, three-layer caching, TTL countdown. If you understand these steps, changing DNS doesn't take effect immediately or two computers find different IPs is no longer a mystery....

The WiFi at home has all gotten slower, and in actual Gigabit tests, it's only a little over 200 Mbps. I almost called 10,000 to request a repair. After a night of thorough investigations, three real culprits were uncovered: the uplink was completely eaten by mobile cloud sync, the 2.4G channel was crowded by a neighbor's newly installed device, and the TV was slow as if it were a slow internet. Attached AX3000T complete inspection sequence, just copy and use it....

My cousin's electric car had a private charger, but the app kept showing the charger as offline, almost treating it as a faulty charger and requesting repair. When I checked the parking space, I saw that my phone had no signal at all in the basement corner. There are three ways to connect the charging station to the internet: ride the WiFi at home, have a built-in 4G IoT card on the station, or use Bluetooth for local backup. If you choose the right spot, you won't have to worry at all....

There are three types of mishaps when casting from your phone: can't find the device, casting with no visuals or sound, or freezing as a PPT. I lined up every TV in the house, and 90% of it was stuck in the discovery layer—the phone was connected to neighbor's WiFi with the same name, the visitor network was isolated, the AP switch was confiscated, and it could be fixed in five minutes according to the numbers....

A neighbor girl got a router, and on the same page, two Mercury MAC1200R differ by 20 yuan. Upon checking, she realized one had a 100G port and one a gigabit port, but the model numbers were exactly the same. I'll break down the Mercury model segments by segment: the positioning of the G tube network port, digital tube wireless speed mode, and the Phantom Light Shuttle M series. I'll also clarify the pitfalls of the Tenda AC, AX, and Pro suffixes, so you won't regret ordering after reading....

The sticker at the bottom of the telecom optical modem is its account book: model, SN, default terminal configuration password, LOID, management address—every line has a chance to save its life. Fault reporting requires SN, account closure and verification requires SN, and accessing the backend requires that fine-print password. I'll explain each of the three optical modems I have on hand, and how to fix stickers that are smudged....
