Windows 10: Very slow upload speeds with PC using Windows 11

I believe my issue may be fairly unique and I have done many checks.I have a poor upload speed in comparison to my download speed and it is causing me some issues. The only device on my network that is affected is my PC, and it happens whether I am running a wired connection or over WiFi. So in summary I have 300mbps download and should receive 11-15mbps upload. What I get is 350mbps download to 1.7mbps upload. I have tried numerous speed tests on Firefox and Edge. I get the same results regardless. I have turned my router and modem off and on. I have checked with my ISP also and at their adv

slow upload speed

I'm embarrassed I didn't think of plugging the ethernet into another computer. Anyway, the result is that the speed on a laptop with the same cable is 91 Mbps download, 39 Mbps upload.
A couple of other puzzles: One is that the download speed on my desktop was around 900 Mbps, which is insanely fast, but the upload speed was under .2 Mbps. Now, after going through several of these iterations of remedies, the upload speed is still extremely slow, but the download speed is now around 32 Mbps, which is about 4% of what it was. But to my surprise, with a download speed of around 30, I don't notice too much difference for what I do. Anyway, awaiting your next suggestion.

With regard to re-installing Windows 10, even with keep my files this seems to be way over the top, as it removes apps and drivers. I find that a bit terrifying.
