Hey thanks for taking the time to respond! Im going to try out the 100/100 and give this ( https://www.amazon.com/TP-Link-AX1800-Dual-Band-Archer-AX21/dp/B08H8ZLKKK ) a go! Good to know I dont need the modem.
what speed do you have (down speed not up) ? Is your stick connected wirelessly or via a network cable (RJ45)? If wireless how far away from your router is your stick? how many other devices use the wifi in your house? What wireless connections does your wireless router support ( A/B/N etc etc)? What is between your router and stick (Brick wall/s drywall)? Have you checked the wifi signal strength by your stick?

Have you actually ran a speed test on your network?
also instructions for running a speed test on your stick:

I know it's a lot of questions but all these things impact your connection. I hope this helps you and others as well.
You don’t need to spend all that if you don’t want to. If your range is otherwise ok (number of bars/signal strength) you should just need 1. The one I have was only $70 and it’s fantastic and range is doubled vs the company provided WiFi. If you want to be sure you can go with something like this- just make sure whatever you get has 802.11 AX (not just AC)

If your house is huge or you want to be extra sure you can get one of the easy MESH systems (which are way better than just extenders) Netgear ax mesh whole-home system for 250
