Bits are bits, everything is a zero or a one.
Step back for a moment and contemplate.
How is your SSD connected?
What brand and model is your router?
Have you tested the speed of your internet connection?
If you are connected via WiFi have you done a scan to see if there are any other connections hitting your house?
If so, what channel are you on compared to the the others?
Almost all internet connections can be improved by buying your own nice high end router.
If everything I just posted sounds like an adult in a Peanuts cartoon, find a tech that specializes in Networking. If you work in a large company hit up your IT department.
