All downloads fail regardless of browser!

I'm at my wit's end. Running Windows 10 with a 100/100 connection and every single download fails or times out regardless of the browser I'm using. I've tried with Chrome, Firefox and Edge, all of them have the same problem. Additionally, and this is probably part of the same problem, but most websites time out with TLS handshake errors as well.

I know it's not my connection. My wife's computer is on the same connection and has no problems. I've tested the connection repeatedly and it's got a consistent 100/100 with 12ms latency. It doesn't matter where I'm downloading from, all of them fail. I can watch the speed I'm getting and it can be running at 10mb, then it will drop to zero and time out. In Firefox, I've turned off the "block dangerous content" but it hasn't helped. I've cleared browser data and cookies. Heck, the first time I booted up Edge it failed, so clearly it's not browser data. I've turned off the Windows firewall. No help. I've tried to adjust the IPv4 and IPv6 settings, no change. I've tried it with my AV turned off, no change. For some reason, no matter what I'm doing, the system will sporadically come to a screeching halt and kill whatever I'm doing online. There seems to be no rhyme or reason to it that I can see.

Any ideas? This is driving me nuts.

Reset Network Adapters in Windows 10 Network Sharing Tutorials

Just did, didn't help.

You can also try [Batch] Windows Network Fix - Pastebin.com Check for suspicious entries in HOSTS.

Saw nothing out of the ordinary.

The worst case scenario: Repair Install Windows 10 with an In-place Upgrade Installation Upgrade Tutorials

Already did. Didn't help. Did a complete reinstall.

While I was at it, I completely reset the router back to factory settings and swapped ethernet ports to one I know works. My wife's computer is now on the port I was using and I'm on hers. She can still download, I still can't. Also ran SFC to see if there were any bad files, came back clean.

This is frustrating.

While not arriving at the cause, perhaps this may help:

Intermittent problems with TLS handshake and being timed out

Basically -- Open a Command prompt with Administrative rights and type: netsh int ip reset

You might also give a shot to TCP Optimizer.

I have it installed, don't know if I've optimized since I reinstalled Windows, I'll give it a shot.

That is not good. It might be a driver issue, check for missing/outdated drivers via Driver Easy Free.

AVG PC Tuneup has a driver updater that I've already run and it says everything is up to date.

Thanks for everything you've tried to suggest so far, I appreciate it.

Interestingly enough, as I've been trying things, I haven't seen the TLS handshake error all day. I'll keep it in mind if it comes back though, thanks.

Cephus404, did you ever resolve this? I'm having the same issue: large files fail in all browsers. But Steam works perfectly fine - fast speeds and gigs at a time with no problem. Maddening, truly.

Not really, no. The problem is still sporadic but I've started to suspect that it may be a hardware problem, perhaps in addition to a software problem. So I'll just limp along as best I can until I get mad enough to just get a new computer.
