Experiencing Slow Download Speeds on Gaming Platforms Despite Fast Internet

For the last couple of years, I've been struggling with painfully slow download speeds across multiple gaming platforms such as Steam, Riot, Battle.net, Epic, and even Arena Breakout Launcher. My speeds typically hover between 500kbps to 5mbps, with rare spikes reaching 20-30mbps. This is frustrating because I have 1GB fiber internet, and I've notice others with much slower connections managing faster downloads than I can achieve. I'm currently using a CAT8 ethernet cable but have also tried different ones with no improvement. Here's what I've attempted so far: - Ensured all ethernet connections are secure in my PC and router. - Ran a malware scan and found no issues. - Checked my drivers, and they are reportedly up to date (I have a Killer E3100G 2.5 Gigabit Ethernet). - Executed command prompts to check for corrupted files—everything's clear. - Factory reset my network settings. I'm at a loss with what else could be causing these slow speeds. I've also noticed in Task Manager that my network activity fluctuates wildly, sometimes dropping to 0kbps, and NZXT PC monitoring shows minimal load during downloads, which is puzzling. Any ideas would be greatly appreciated!
