your speed of 39 megabits download speed isnt particularly good. its good compared to the ADSL (copper phone lines) but its comparable to the 4G network that currently exists in parts of the island already.
its likely that your speed is limited by the speed of your Wifi device and that buying a faster wifi access point (one that follows the WIFI 6 standard for instance), or, directly connecting your computer into the router with an ethernet cable will bring you much faster speeds.
the speed you have is plenty fast enough for web browsing, or watching Netflix, so its possible you dont need it to go any faster.
