Downloading Update is Slow

Hi,

I am trying to upgrade the packages, but the download of the package is very slow, it takes more than 10 minutes just to finish the download and would sometimes Connection Timeout.
Meanwhile, the CPU is always hovering at 15% and the Memory Free 75MB, Used 53MB, Total 128MB

The mikrotik is the RB951G-2HnD.

However, doing a speed test at https://speed.cloudflare.com/ from the laptop yields 20mbps, consistently.

How do I troubleshoot it?
