Extremely slow networking with one specific PC

Understood. But if we are trying to determine if this is a NIC/hardwre error or a software problem.

Most of the posts here have suggested that it's a hardware problem. Since I have 7Mb upload over the NIC to the internet, but only 200kb upload over SMB, I think this means there is a software situation.

On top of that, I just transferred 800+ MB relatively quickly to the same machine that can't copy files over SMB using a different program.

So, and I may be going out on a limb here, I think that there's something messing with my windows file sharing, not my NIC.

Ok, but do you ping perfectly? Takes only a minute or two to check.

(I thought I replied to this, but it must not have posted...)

I just ran ping both locally to my client and on the client. No problems, <1ms response time on all tries.

I have a code-source program running on the "server". I used that to transfer 800MB of data within 20-30 seconds to the same client that gets 26kB/s over SMB.

So I think the problem is with Windows Networking.

I agree--it seems not to be a hardware problem then!

No answers here. I am going to try and repost with a better headline and more info in the first post. Maybe I can get some help on it...

I'll give that a shot.
