I've been struggling with slow internet speeds for over three hours now with my ISP. I can't connect to Zoom, VPNs, or virtual machines effectively. When I run a speed test at the default server, I get over 800 Mbps download but under 10 Mbps upload. Switching to a speed test server from another company nearby shows much better results: over 800 Mbps down and 600 Mbps up. However, when I try another server from my ISP, the speeds drop back to 800 down and 10 up.
I've reached out to my ISP, and they keep questioning my hardware setup, asking things like how far I am from the Wi-Fi router, but I'm on a wired connection. I've tried various Ethernet cables (rated CAT 5e, 6, 6a, and 7) and multiple ports on the optical network terminal (ONT) without success. All signs point to an issue on their end since I only see these slowdowns when using their servers. It's getting frustrating explaining to them that the problem seems to lie with their routing. What else could be causing this if my speeds return to normal on other speed test servers?

What ISP are you using? I saw Spectrum having issues recently, which could relate. If it's not them, consider running a direct connection by hooking up your PC without any routers—this can help rule out hardware issues on your end.
I went through this with my ISP too—they always point fingers at anything except themselves. Try using the ISP's router directly connected again and document any test results. If you're still seeing those speeds, call them back and emphasize that you've tested it without your own equipment.
I totally get your frustration! It seems like you're already on top of the basics, but I'd suggest clarifying what you mean by 'normal speeds' when using different servers. Remember, actual services like Zoom won't run from the speed test server, so it might not reflect real performance. Sometimes it's about network routes—not just the static speeds. Have you checked if you’re getting stable ICMP or TCP connections too?
Make sure to ask your ISP about known issues in your area or with their equipment. If possible, use their router with just your PC for testing. Check if their speed tests fit within what's promised and if they're out of spec, that could warrant a proper complaint.
