Working with Raspberry Pi files

Some reference on how to connect to a Raspberry Pi running in the same LAN network. I’ve been using Raspberry Pi running in home, for last 10 months. Until a month ago, the sole purpose of the RPi is to filter off the ads using Pi-hole1, then a speed test module was scheduled to run on it. By the setup, the speedtest-cli runs every 10 mins and fetches internet into csv file.
