Windows display link speed as 1000/1000 instead of 2500/2500
Windows display link speed as 1000/1000 instead of 2500/2500
I've set up ATT fiber with the BGW-320 router, CAT-5e cables, a Z690 motherboard featuring an Intel I225-v port, and switched my network adapter to full duplex 2.5GB. After installing the latest drivers, the speed remains at 1000/1000. The new cable didn't work and I've tried all the manufacturer and Intel drivers. There might be a hidden bottleneck or missing configuration—have you considered checking other settings or waiting a bit longer? I saw the issue resolve on my end after a couple of weeks without further changes. My connection now shows 2500/2500 speed. Hope this helps for anyone facing the same!
Certain boards feature multiple LAN ports, usually combining 1Gbps with a higher speed option. Is your board among those?
The guide mentions needing a high-speed port for 2.5Gbit connections. It suggests using a switch or similar device to handle the required bandwidth. Some ports are limited to 10Gbit, so ensure compatibility if you need that level. Cat6a is recommended for such speeds, not just 10k or 100k. The advice seems a bit unclear, but it highlights the importance of checking port capabilities before connecting.
Only one port on the motherboard is available (labeled 2.5gb). Initially, I thought it would be straightforward, but after reviewing the manual, the ONT port supports 2.5/5gb and the Ethernet ports are 1gb and 5gb. I confirmed I’m using the 5gb Ethernet connection. EDIT: It seems the note might mean the port I connect the router to from the wall is limited to 1GB.
The configuration would likely involve a wall jack, a switch with 5GB Ethernet capability, and a PC connected to a router. If the router's ONT port is limited to 1GB, adding a switch afterward wouldn't make much sense. This setup seems unusual for ATT's 2GB plan, especially since the router's port can't handle more than 1GB. It's unclear why a 5GB port would be used if it can't support higher speeds.
ONT or fiber is intended for WAN connections. You can link a switch between your router and your PC via the 5Gbit port. The fiber port supports SFP+ and can handle up to 10Gbit, though your document mentions Cat7 is required. It seems Cat5e might work on very short cables, but the specs suggest direct PC connection is possible. You can attempt to connect and adjust the port speed to 2500Mbps to test connectivity. It’s likely you’ll want to check if the fiber port provides 2Gbit speeds. Regarding internet access, it probably comes from the ONT rather than the fiber port itself.
Apologies for the delayed response. I didn’t review the thread the following day and chose to investigate when I had extra time. Today I verified my network connection, which appears stable now. There’s no need for driver or Windows updates since the issue resolved on its own. My download speed has improved from 1000/1000 to 2500/2500. I hope someone trying this in the future finds a better fix, but perhaps taking a short break could help things settle!
