The computer becomes sluggish or stops during file transfers.
I noticed you didn't mention earlier, but I reached out to my ISP yesterday and they spent about an hour and a half trying to resolve the problem. They said there were no issues from their side. We tested speeds on various devices—phone, tablet—and even tried it on a borrowed PC. The only hiccup was with my own PC; other devices handled downloads and uploads normally, while mine lagged between 10-12 Mbps upload and 70-80 Mbps download. The borrowed PC worked fine on AM4. It seems the issue might be related to the LAN port or possibly the MOBO. I’m unsure if my country has MSI warranty support, which would complicate things. I’m considering staying without a PC until then, which could impact my job. I’m thinking about using a different LAN adapter, but that would just delay the fix and might cost more than I can afford. I’m worried my assumption might be wrong, so I want to double-check before deciding. Thanks for your understanding.
Do you have any third-party firewall installed besides the built-in Windows firewall? It’s possible you might have both active at the same time. You can remove the other one and rely on Windows’ native solution. Usually that works fine. #2 If you find a Windows 10 ISO, you can install it and test it if needed. Check the upload speed or try using Linux for a more accurate measurement. This could help identify if Windows 11 is the source of the issue. It’s not too much effort, and I get it if you’re short on time. It’s your choice. #3 Having multiple Ethernet and Wi-Fi connections running at once can create conflicts. Are you only using one connection right now? If you get a new separate Ethernet card, make sure to turn off the existing one—either through BIOS or the Windows Device Manager.
Here’s a revised version of your text:
I checked out Linux and created a bootable USB with Rufus using the Linux Mint version. The outcome was quite unusual. After launching the OS, I opened Firefox and ran the same upload tests. I was streaming a latency test video from YouTube in the background while testing, which helped me notice some changes. The audio crackling disappeared, and the test from testmy.net completed more quickly. I increased the upload speed from 14Mb to 100Mb, but still didn’t see any audio issues. However, my mouse remained sluggish—less noticeable than on Windows, but still present.
I then ran a speedtest.net check. The background latency video would randomly disappear and reappear after each test. Additionally, the upload speeds didn’t improve even though the default test from testmy.net finished faster; the results still indicated my connection was slower than the host’s average. Speedtest.net showed normal downloads but only 10–15Mbps for uploads.
I’m unsure if the USB drive was the right approach. Maybe installing Linux directly onto the SSD would have been better, as most online guides suggest using a USB for troubleshooting. I’m unfamiliar with Linux and didn’t want to risk further complications, so I went that route. Could you confirm whether this method was correct?
A few notes: I started with Windows 10 but switched to Windows 11 to see if the problem persisted. I assume it wouldn’t matter if I tried again. I also had Malwarebytes installed; it’s possible its firewall settings could have interfered, though I removed it a few days before this issue. Could there be lingering effects from that program?
I contacted my ISP during troubleshooting, who suggested disconnecting all devices except the affected PC—both wired and Wi-Fi. This likely means the problem is specific to my computer.
It seems the issue isn't limited to Windows 11; problems also occurred with Windows 10 and Linux. Your network tests used various devices, so double-check that the cable is intact. You might consider turning off the built-in Ethernet and using a regular PCI-E card if you want to investigate further. We can't confirm whether the motherboard's Ethernet module or another component is the cause.
It seems the issue lies with MSI 'pro' boards and possibly your ADATA SSD. Those are the concerns I noticed right away. I’d prefer a different motherboard like the MSI Mortar series—especially the newer models with reliable BIOS—and a fresh installation. Make sure you have a high-quality SSD, such as from Samsung or Crucial, and address any storage problems beforehand.
