How do you use a phone to use the printer scanning function? My dad's old tin box, my mom's 23-page medical report, my niece's test paper—I scanned them one by one using WeChat mini programs, vendor apps, and computer network scanning. The mini program defaults to switching files with blurry text and requires a file change. Old photos are 600dpi and 5MB per page, and the scanner list is empty and the trap is stepped on for you....

The 4TB drive was full again, so I linked the free Alibaba Cloud drive to Feiniu as a local drive, and the TV played movies directly from the cloud drive. How to choose the three roads, the account of the three-party benefits package with speed limits, and the must-not do anything on the mounted drive—test it shows a month of solid results....

Helping my cousin set up remote desktop port mapping, and when entering external port 13389, he asked why, and I realized I had always only half understood port numbers. Find the IP address and the port, then the room. The 65,535 accounts are divided into three tiers. I organized the frequently overlapping household accounts into a list, and 8,080 was occupied in three steps to find the real culprit....

The Mijia app is enough for daily checks, but it can't handle things like changing DNS, manually selecting channels, or enabling IPv6. I went through the commonly used and advanced settings in the Xiaomi router's web backend one by one, compiled this menu map, and listed which 7 things require running the computer and running 31.1 to do it....

How do I type files received in WeChat from my home printer? No need to transfer to a computer—Apple uses AirPrint, Android uses default printing service, and elders use WeChat Mini Programs directly. I accompanied my mom through each of these three routes, and even explained the three pitfalls where printers can't be found....

Changed routers and printers, but now they're offline and can't find the icons? Don't rush to reinstall the driver yet. Check the lights, check the router device list to distinguish whether it's a network drop or disconnection, change the IP port and port, only recognize 2.4G on the network card, and reconfigure the network after changing the WiFi name. The three real culprits are identified accordingly. I fixed it in half an hour following this order....

Helping my cousin rearrange the weak current box, the Mercury's system light stayed on quietly, while the Tenda AC10 system light kept flashing beside him. He thought Tengda was about to break. This article explains exactly what the SYS, WAN, and LAN lights on Tenda's panel are responsible for: Tenda's rules are the exact opposite of the new Mercury model—SYS flashing is the real heart rate, staying on and not moving is actually a problem, and the machine used as an AP has to read the lights according to the position....

Optical modem overheating is not the same as router overheating; routers complain about lag, while optical modems speak about light degradation. My weak current box feels hot to the touch in summer, with light degradation climbing from -21.8 to -24.6, and the network speed dropping to 760 Mbps. I tested all three cooling techniques one by one. When the temperature drops, the light decay really returns, and you get a good idea of how much each move lowers....

SSH is the backdoor outside the NAS web backend—checking logs for stolen drives, installing deduplication tools, checking if the hard drive recognizes it—all rely on it. This article covers the specific paths for enabling SSH between Feiniu and Synology, the five commands I use most frequently after connecting, and the lesson I learned about being scanned every day for half a month when I tried to forward port 22 to the public network for convenience....

Video calls get stuck on PPTs, while the same WiFi webpage opens instantly. This half-paralyzed network is almost certainly because TCP and UDP are running smoothly and packets are lost. Using registered mail and mailbox inserts, I'll explain the differences between these two protocols, include a comparison table for each app at home and the pitfalls of choosing the wrong protocol for port forwarding....
