How to view Netsh WLAN Show Interfaces? Signal, negotiated speed, and channel are all in these lines. If your laptop's WiFi is slow, just click on them first
Laptop WiFi is slow, and trying to guess signal bars over the phone is useless. Windows comes with a built-in command netsh wlan show interfaces. Signal percentage, negotiation rate, channel, and bandwidth are all on this screen. The root cause of my old Sun's laptop getting stuck at 200MB is that I had him type this line and it would see clearly....

Why does WiFi signal drop by only one bar while internet speed drops by half? The router and phone were secretly shifting, so I copied down the gear shifter
The living room speed test was 940 Mbps, but by the bedroom it was just over 200 km/h left, and the signal icon had only dropped one bar. After searching for half a night, I finally understood: the grid count is about whether you can hear it, while the internet speed is about whether you can hear clearly. The router and phone secretly switch QAM settings every few tens of milliseconds according to the bit error rate. Every 6dB difference in signal-to-noise ratio requires a step down. The comparison table at the end of the article helps you locate which level your WiFi is stuck in....

Why is the speed test for gigabit broadband WiFi only 600 Mbps? Bandwidth, negotiation speed, and actual speed are the three main accounts, and I spent the whole night checking them
My cousin brought his phone and asked: WiFi shows a connection speed of 1201 Mbps, broadband shows 300 Mbps, so why is the speed only 187 Mbps? Three numbers, three samples. I separate bandwidth, negotiated speed, and actual speed ledgers. Who's bragging is deducting taxes—everything can be matched at a glance, and the slow network checks follow a clear order....

What do 2x2 and 4x4 router antennas mean? The phone's speed is stuck at 867Mbps, so I have calculated the spatial flow issue clearly
What do 2x2 and 4x4 routers mean? It's not the number of antenna roots, but the number of spatial streams. Phones are almost always 2x2, and a 4x4 router is useless against a single phone. This article explains how to calculate negotiation speeds for 867, 1201, and 2402, and includes a command to check your device's current status....
