Connectivity problems with fiber link
Connectivity problems with fiber link
I suspect there might be a problem with your network routing. You mentioned having a full bandwidth but experiencing instability especially at night. Your speed tests show good performance during the day but drop significantly in the evening. The discrepancy between your ISP's claim and your own tests suggests an issue with how data is being routed or delivered. Since you've tried various changes—switching devices, updating firmware, and testing different servers—it seems the core routing could be the problem. If you can confirm whether other devices on your network also face similar issues, it might help pinpoint the cause.
If there are routing problems, the solution largely depends on the ISP or their network partners. The best approach is usually to inform your ISP and see if they investigate. If not, you're likely in a difficult spot. It seems one of their peers might be overloaded during busy times and isn't willing to help. The only workaround could involve employing a tunnel or VPN that routes through an uncongested path of your ISP, though this would require some trial and error and may involve additional costs.
This would also boost my ping and overall speed, wouldn't it? That’s definitely not an option for me. I need to handle several stable streams simultaneously while staying connected to game servers, Parsec remote control, and other services. All tests have been done via a direct connection to my router. The fiber ends in the basement, followed by an ONT converter right next to it. Inside that converter, my Cat7 Ethernet cable connects straight to my apartment and then to the router. I’m the only one using this setup in the building. I’ve already told my ISP three times—seeing if they can resolve this or if moving is the only choice. Thanks again!
Edit: For clarity: only the upload is affected, download remains stable.
Technically it's possible, though if your chosen path is already flawed the overall latency might still decrease. In certain scenarios an ISP’s routing can follow such a complex route that even with proper operation you end up with reduced delays. It hinges on whether you can secure a more direct connection to the gaming servers. This concept relates to gaming VPNs, which aim for closer proximity to servers than an ISP could provide. If you locate a more closely connected VPN, latency will likely be lower than the path your ISP takes. Think of it like roads: your ISP only connects through specific intersections, potentially causing long detours. However, one early intersection might connect to a VPN that accesses entirely different routes, offering a significant shortcut. It’s generally a temporary fix while you wait for improvements from your ISP.
