I'm on Unraid 7.1.3. The plugins installed are: Appdata Backup, CA Auto Update Applications, CA Cleanup Appdata, Community Applications, Dynamix System Temperature, Fix Common Problems, and Unraid Connect. I have 9 dockers running and 1 VM. My hardware is a basic PC with a Gigabyte motherboard, Intel 4770 CPU, 16GB DDR3 RAM, LSI 9300-16i SAS controller, 9 HDDs, and 2 SSDs. My internet is ATT 1gb fiber. I have an Asus router behind my ATT Gateway with IP Passthrough. I don't think I missed anything relevant, if so please ask. Diagnostics file in attached.

I have my server setup for my dad and a friend to access media files remotely. However, we've encountered a problem recently: video playback would pause intermittently. To troubleshoot, we tested file transfers from the server to our local network and achieved maximum speeds of 1 GB.

Transferring files via Wireguard over a 500 MB fiber connection yielded sporadic speeds, ranging from 500 KBPS to 16 MBPS, with most results on the lower end. This suggests that the issue may be related to the Wireguard connection.

To further investigate, I set up Wireguard on my ASUS router and configured it on my laptop. The results were promising, with transfer speeds maxing out my local connection (approximately 300 MB). However, when I disconnected from the ASUS router's Wireguard and connected to the Unraid server's Wireguard, speeds dropped back to their original low levels.

I read a related thread on the Unraid forums where a user experienced a similar issue after upgrading from version 6 to 7, but their problem was related to slow SMB performance. They resolved the issue by using NFS instead.

Since I can saturate my local 1 GB connection, I don't think this is an SMB-related problem.

I initially posted my issue without specifying a solution. To clarify, I'm looking for a way to revert the Wireguard version on my system to the one included in Unraid v6. Alternatively, if that's not possible, I'd appreciate any advice on resolving this issue. If not, I may attempt to install the Wireguard Docker and set it up manually.

Did you get this fixed? I’m having similar problems

No I have not. I'm convinced it's due to the updated WireGuard in Unraid. After testing Tailscale, my speeds returned to normal, but I'd prefer to use the built-in WireGuard. I attempted to set up the Docker WireGuard, but I'm unsure about the process. My site-to-site VPN setup with my friend is where I get confused. For a personal setup, Tailscale seems to work smoothly. However, I'm not familiar with Tailscale, and it would require me to share my network with their servers.

Thanks, after some testing I also believe it's Unraid's WireGuard implementation.

I am using this for plex streaming and using Wireguard get constant buffering (i was using this same setup before 7.x completely fine). Decided to setup tailscale for a test, and using tailscale is flawless. I then decided to try the wireguard docker and that also worked flawlessly.

Yep, same results for me. My friend upgraded his Unraid to 7 and it is the same thing for him. I can't believe this isn't a bigger topic on here. I couldn't find a peep about it until me and you posting.

I really would have thought some of the Limetech folks would have chimed in. I think this is a bug with the built in Wireguard.

I added this thread to a thread created by xreyuk in the bug section. I want this to remain open but hopefully it'll gain more traction. I've seen more traction to other's threads with much less information posted. If someone sees anything in this thread that needs to be added in order for folks to give suggestions on fixing our issues please let me know.

I am having the same problem with my plex install and wiregaurd running unraid 7.1.4.

I downgraded from Unraid 7.1.4 to 6.12.15 and this resolved the Wireguard slow transfer issue. So it is definitely something with the updated built-in Wireguard.

WireGuard is included with the Linux kernel, I suggest looking for any general Linux bug reports about that:

6.12 uses kernel 6.1.x

7.0 used kernel 6.6.x

7.1 uses kernel 6.12.24
