I recently made the switch to Linux and installed Kubuntu 25.10 on my desktop. So far, it seems stable, but I've been experiencing a major issue with my internet speed. Initially, I had a tough time with my WiFi antenna not being recognized during installation, which I think may have caused driver issues. After some struggles, it finally connected, but now the speed is only around 20 Mbps when I should be getting over 100 Mbps. I'm trying to figure out how to install the right drivers for my Gigabyte H410M motherboard but the information I find is quite confusing and I'm worried about messing things up. My setup includes an Intel Core i3 10100 processor, a GTX 1660 Super GPU, and 16GB of RAM. The WiFi antenna I'm using is a TP-Link TL-WN8200ND. Can anyone offer guidance?

A hardwired connection is usually more reliable during the installation to avoid these kinds of issues. It’s a bit tricky if you’re not familiar with the setup, but it really helps to get a stable connection first. I recommend connecting your PC directly to the router using an Ethernet cable whenever possible until everything's sorted out. This way, you can ensure if the problem lies with the WiFi or the system itself.
You should definitely share the model of your WiFi card! It sounds like your TP-Link TL-WN8200ND could need specific drivers. Have you tried connecting directly via Ethernet? That might help you rule out if it’s just the WiFi that's slow. Also, check if other devices on your network are running fine, like your phone or laptop.
