Ethernet adapter problem? Slow browsing and downloading/ constant buffering on video

My PC used to handle video fine without any problems. We mainly use BBC Iplayer. Then about a month ago video started buffering on video sites more slowly than usual (coincidentally after heavy rain). It would play for between 1-3 minutes for fine, and then pause to buffer for a minute or so, and it would do this continually, with the quality of the video changing to low and then changing back to HD. For some strange reason it didn't affect video sharing sites such as youtube/vimeo/dailymotion etc. We checked netflix and Prime video and the quality would change in a similar fashion, although the buffering was not as bad, it still had problems and didn't play smoothly. We've since had to start experimenting on multiple unofficial websites to test the problem, and the majority of them all buffer the same as Iplayer. For some reason the only websites I've found which buffer normally (apart from youtube) are 123movies.md, the123movies.com and 123movies.cafe, I've absolutely no idea why. I've tried many many different sites, what is different about these 3? I'm hoping someone knows about the different types of video players different websites use? I've tried a different browser and that made no difference either.

I thought I would try testing if my spare cables would make a difference, but they didn't. Also when I unplugged and re-plugged the ethernet phone cable (connecting the router to the micro filter/BT phone socket) for some reason the PC wouldn't connect to the internet (the internet symbol showed a yellow exclamation mark instead of the PC symbol). I unplugged and re-plugged it again and at one point it even notified me that the ethernet cable wasn't plugged in! It took a few minutes after which it connected (without me doing anything).

But the buffering problem remained. Since then the problem has got a bit better occasionally (temporarily), and sometimes a lot worse, but it hasn't gone away.

I am with Origin Broadband and my average speeds are 9.3 Mbps, and in general since this problem has started the strange thing is that it hasn't affected the speeds recorded on speedtest.net, I do now get drastic drops to around 3 Mbps or even 1 Mbps occasionally but they only last a few moments-I re-do the tests and they are back to normal speeds, so I'm not sure if they're an error in the test.

The strangest thing is that it happens on PC, but not on other devices connected such as tablets and the laptop. I've never experienced this before! It even stops me downloading anything, if I try to download a 200MB file it will take hours and keep failing, stating network error. I think it's an ethernet issue so I updated the driver to the latest from the MSI website but it made no difference. I also bought a new SSD and did a fresh install of Windows on that but it hasn't changed anything.

I am now thinking the only solution is to buy another motherboard to get a new ethernet adapter, but am worried if even that doesn't fix the problem I would have wasted money. I was told buying a 3rd party external USB ethernet adapter wouldn't actually 'replace' the onboard one, so it would only provide a solution if the actual physical port to the onboard adapter is damaged (and not the adapter itself).

I can't see any damage on the actual physical port/connector where the ethernet cable plugs in. I'd love to be able to buy some cheap ethernet adapter that would fix the problem but am guessing that won't help so instead of possibly wasting money on something I'm thinking I should just look for a cheap motherboard compatible with my current build, unless someone can help diagnose/fix the problem with an alternative solution. Any ideas ?
