What does Router MTU mean? If you can't post WeChat images or some websites won't open no matter what, it's probably because the numbers aren't right
The router MTU is the maximum number of bytes a network packet can hold. Ethernet defaults to 1500, but dial-up internet requires 8 bytes, reducing the overhead to 1492. Typical symptoms of incorrect settings include instant text sending and spinning WeChat text, some websites failing to open, but everything else works fine. Using ping -f -l in three steps, you can measure the numbers you need to fill in at home....

What is the difference between WiFi 2.4G and 5G? Which phone connects faster? I walked around the house to test it, and the answer was different from what I expected
There are two WiFi names at home—one with 5G, one without. Which one does your phone actually connect to? I held my phone and tested it in four rooms: the living room had 5G three times faster, and two walls separated by 2.4G, surpassing it. When to connect which one to use, why the dual-band integration is a trap—here's a chart for you....

What is the difference between a router's WAN port and a LAN port? Plugging the network cable into the wrong port means WiFi is full and there is no internet. I moved a cable and only then understood
The network ports on the back of the router are divided into WAN and LAN, with one pipe for incoming and one for output. The night I plugged the fiber modem into the router cable, the whole house's WiFi was maxed out but I couldn't get online. This article clearly explains the difference between two mouths, three tips for identifying them, symptoms of inserting the wrong mouth, and how to fix it....

How to choose a router bandwidth of 20/40/80/160MHz? Even with 160MHz on, the phone is still 1201M. I've stepped through all three hurdles one by one
Bandwidth is the most easily overlooked parameter in WiFi settings. I thoroughly investigated the issue of AX3000T at 160MHz but phones only having 1201M: what exactly is the difference between channel and bandwidth, the account of doubling bandwidth and doubling speed, the hidden pitfall of 149 to 161 not making 160MHz, and how various brands adjust bandwidth in the backend—everything in one go....

What does router AP isolation mean? If you can't find the WiFi screen on your phone or computer when casting, it's probably this switch
Even if your phone and computer are connected to the same WiFi, you can't find the TV when casting, and you can't find the other party when sending files, yet the internet is all normal—most likely because the router's AP isolation is working. I accidentally opened it once and explained the principle, the locations of each brand's switches, and the troubleshooting sequence in one go....

What does a MAC address mean? What is the difference between an IP address and an IP address? Let's explain the random MAC of a phone all at once
What does a MAC address mean? It's an ID card that burned out of the factory with the network card, and the IP address is the address issued by the router—one stays the same, the other changes. The router binds to the speed limit, and if blocked, it recognizes all MACs. The default random MAC on your phone can cause these functions to fail collectively. This article explains the differences, tips for identifying devices, and how to choose the random MAC switch....

Should you enable router firewalls, SPI, and DoS protection? I tested the SPI acceleration theory and changed the switch back to its original state
On the router's backend firewall page, there are two switches: SPI firewall and DoS protection. Old tutorials online say turning off SPI can speed up. I tested them on both ASUS and TP to talk about what these two switches actually do, who should turn them off, and what pitfalls you might fall into if turned off incorrectly....

Should you enable the WiFi 7 router MLO? After a week of testing with both 2.4G and 5G on the phone, the fastest scenario was just one scenario
MLO is WiFi7's multi-link technology, allowing the phone to connect both 2.4G and 5G links simultaneously for transmission and reception. I tested it for a week with the BE3600: internal network file transfers were indeed 30% faster, but the speed test on gigabit broadband showed no change, and I was even forced to reconnect the disassembled dual-band band. Three types of people drive it that feels great, while three types of people use it purely for electricity....

What is the purpose of a router's USB port? Hard drive insertion, 4G emergency, download device—I've tried each of these four methods
The USB port on the router is really not just for show. Plugging in a hard drive to become a file server, a 4G internet card as backup broadband, a hard drive as a download machine, and connecting a printer for the whole family—I've tried these four methods one by one. Which machines are worth the hassle and which are just for show? This article explains everything clearly....

What does router QoS mean? Should you turn it on? My family downloaded my game and it was 460, fully understanding this switch
Router QoS is a switch that divides data into fast and slow lanes; it doesn't increase bandwidth, only determines who goes first. If someone at home gets lagging as soon as they download FamilyMart or game ping spikes to over 200, it's most likely time to try it. However, you need to correctly fill in 85% to 90% of the measured bandwidth; if you fill in incorrectly, your whole family will see slower speed. This article clearly explains the principles, pitfalls, and the positions of various switches from different brands....
