Are Intel BE200 and BE201 interchangeable Wi-Fi 7 modules?

The BE200 and BE201 belong to Intel's Wi-Fi 7 family, but their similar names conceal an important host-interface difference. A successful upgrade begins with the computer manufacturer's supported configuration, not the largest wireless rate printed in a listing. Check the exact laptop or motherboard service information, socket interface, antenna arrangement and supported firmware. Do not infer compatibility from the presence of an M.2 connector alone. Different uses of that connector can require different electrical support.

How do Mbps and MB/s differ in game-download readings?

A game client reporting 50 MB/s is not necessarily underperforming on a 400 Mbps connection. The first number counts megabytes per second and the second counts megabits. One byte contains eight bits, so the units must be aligned before judging the result. Multiply a decimal MB/s value by eight to express it in Mbps. For example, 25 MB/s corresponds to 200 Mbps, while 100 MB/s corresponds to 800 Mbps. These are unit conversions, not predictions of what a particular connection will achieve.

When is flushing the Windows DNS cache useful?

A DNS cache stores recently learned name information. Clearing it can help when Windows retains an obsolete answer after a legitimate service change. It is less useful when the actual failure is weak Wi-Fi, an unplugged cable or an unavailable website. Write down the affected hostname and whether other destinations work. Compare another device on the same network. If every application fails and the computer has no usable network address, resolve that earlier connection problem before treating DNS as the cause.

Why is Windows Wi-Fi link rate higher than download speed?

Windows may display a wireless link rate much higher than the result from a speed test. These figures describe different things. The first concerns the radio connection; the second measures useful traffic across a longer path that includes additional equipment and services. Use Windows network properties or the documented netsh wlan show interfaces command to inspect the active connection. Note the band, receive and transmit rates when available, adapter model and test location. These values can change as radio conditions change.
