Network connectivity problems Internet access challenges
Over the last month my computer's internet and ethernet speeds have dropped noticeably. Everything else is functioning properly. I've replaced the TP Link under my desk and the ethernet cable, plus updated the motherboard drivers, but the issue persists. Any suggestions? Wireless speed has gone from about 30mbps to roughly 90mbps, while the Ethernet connection now offers around 1.75Gbps. Motherboard model is b450m dS3H WiFi. No troubleshooting steps have helped.
I managed to resolve the issue temporarily by switching the link, but after a day it stopped working again.
I suggest starting from a fresh Ubuntu live system to check if the speed problem persists—if it does, it suggests a network hardware issue. If it resolves in Linux, the likely cause is a software problem. Since it affects both wired and wireless connections, the issue probably lies with your router.
Start by checking your internet connection on another device. If both share the same issue, the problem likely lies with your own computer. Verify that all relevant drivers—chipset, Ethernet, and Wi-Fi—are up to date. If no updates help, boot from a Linux live USB to test connectivity speed. Should the issue persist, try restarting your modem and router, switch to a different Ethernet cable, or alter your Wi-Fi network name and password. If changes don’t resolve it, reach out to your ISP to confirm the problem isn’t on their side. Good luck!
Caught a wild moment in the dark—don’t laugh, I’ve played a prank on a friend this way. Make sure your router’s settings are correct and that no speed limit was applied to your device. Apart from that, do you have a network card available for testing Wi-Fi or Ethernet? When you tried another computer, did you use the identical cable and port on your router? Have you looked for any updates for your router? Did you switch it off and then back on again? (just a joke)
It's late here, so I won't type everything out. I suggest running some iperf tests. They're simple and give accurate speed measurements. Check this guide: https://www.techtarget.com/searchnetwork...throughput. If you have several devices, try this path: WiFi -> WiFi -> LAN -> LAN -> LAN WiFi -> WAN -> WAN. You can use public hosted iperf servers for the WAN and then test your local connections between devices. This should help identify network issues or problems upstream.
