W11 slow SMB speeds
W11 slow SMB speeds
Hi everyone. I’m a W7 user, and I’m being honest about it. With games now cutting me out and my PC already in messy shape, I thought switching to the new version would be a good idea. That’s what I did—I installed Windows 10. Right away I felt a strong dislike for it. I really don’t like Windows 10. Then I moved on to Windows 11. It’s okay for now. The problem is with my Synology NAS acting as a media server. In W7 I got full gigabit speeds when copying or streaming. With W11 (and even W10) I’m stuck at about 2MB/s. Sometimes adjusting the SMB settings on the NAS brings it back to normal, but then it drops again after a reboot or a few minutes. The settings in the NAS client stay the same, which is odd. After checking the logs, I saw that during slow periods the system switched from IPv4 to IPv6. I turned off IPv6 for my Ethernet card and it now consistently handles gigabit transfers from the NAS. Still a bit strange, though. I’m planning to disable IPv6 on the router’s DHCP settings. All this was clear while I was writing this. Thanks in advance!
What are your computer specifications? There seems to be a problem with AMD processors and Windows 10 that might be related.
It turns out I never enabled IPv6 in the router. I just moved to IPFire and wasn’t sure while typing. To fix it, I turned off IPv6 in the Windows adapter settings on my PC. I changed the router to OPNSENSE, and now I’m certain IPv6 is disabled. Still, my devices keep getting IPv6 link-local addresses, which surprised me. I’m not very familiar with IPv6. If anyone has a quick explanation for this issue, it would be helpful—I’m running an X5650 on a Gigabyte X58 motherboard.
