Is the Xiaomi AX3600 still worth buying? Bought a second-hand dedicated 2.4G feeding unit for 95 yuan, and the problem of 40 smart devices disconnecting at midnight didn't happen again for a month
At home, about 40 smart devices were all crammed into the old AC2100's 2.4G, and the speaker vacuum all went offline late at night. I bought a second-hand Xiaomi AX3600 for 95 yuan. Back then, it was a first-generation WiFi 6 flagship that cost 599 yuan, with six cores and 512MB of memory. After switching to an IoT private gateway, it only lasted a month and disconnected to zero. Includes five steps for second-hand machine inspection and a complete setup sequence, clearly explaining who should be accepted and who should not be touched....

How do you set up a university dormitory router? Campus network authentication blocks half the population first; power outages and floor-wide WiFi are not encountered at home
After dropping off my niece to check-in and installing a dorm router, I realized campus network and home broadband are not the same thing: there are three authentication methods, and if you don't understand before buying a router, you might waste money. Web verification is completed in three steps. Don't force client verification, plus WiFi conflicts across buildings and power outages at 11:30 PM—I've noted all the pitfalls....

How to back up a NAS to NutCloud? The free version uploads 1GB of data per month, and I only picked these four items to put up
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....

What do the Mercury router indicator lights mean? The old and new SYS lights follow the opposite rules: disconnect the internet, check the light first, then proceed
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....

Should telecom optical modems be restarted regularly? Every night, I cut out the power for two years and saved seventeen yuan. My mom's cat's light degradation doubled
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....

Can a NAS external hard drive be used as a warehouse drive? After three months of testing, the power supply system dropped three pitfalls
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....

What does DNS resolution mean? After typing the URL, press Enter to open the webpage. I ran the steps in the middle using nslookup
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....

How to troubleshoot a Xiaomi router with slow internet speed? The gigabit dropped to just over 200. I investigated all night, and three of the real culprits were still stacked together
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....

What should you do if there's no signal when installing a charging pile in an underground garage? If the pile shows offline, don't report for repair yet. I've tested all three network connections
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....

Can't find the TV when casting on your phone, no sound when casting? I checked these three layers, and a 90% chance of a failure would be fixed in five minutes
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....
