It is considered to be the fastest among home use, but it is only for home use.

In addition, let me explain to you a little bit what the so-called 2M means.

The unit used to describe network bandwidth is different from the unit used to download software.

2M is a description of network bandwidth, which does not mean that your download speed is two megabytes.

2M is the abbreviation, and the complete writing is 2MB/bps

The unit of download speed is 2MB/s, and their relationship is 1MB/s=8MB/bps

Just divide the bandwidth by 8 to get your theoretical download speed.

If your bandwidth is 2M, then your actual theoretical download speed should be 2048/8=256KB/s (1MB=1024KB)
