I've recently upgraded my router and switched to an ethernet connection on my PC, but I'm facing a frustrating issue where my download speeds are capped at around 9 Mbps. I have a 1 Gbps internet plan and typically only a few devices connected to the network. I've checked all my settings and confirmed that nothing should be capping my speeds. I've also tried using different ethernet cables, all of which worked fine with my consoles during testing. When I was using a WiFi card, the speeds were not this slow, but I had to remove it for my new graphics card. This situation is really inconvenient, and I could use some help figuring out what's going wrong.

If you're using the onboard network adapter, it could be a driver issue. Check the motherboard manufacturer's website for the latest drivers. Alternatively, consider getting a USB Ethernet adapter; they’re relatively cheap and could potentially resolve your speed issues.
It’s possible that the Ethernet port on your PC is only a 100Base-T, which would explain the speed limit. This type can handle about 11.1 MB/s maximum. If you're intending to use higher speeds, make sure your connection supports at least 1 Gbps, especially if your ISP doesn't cap you at 100 Mbps.
When you download something, are you sure the speed being capped is from your network and not your hard drive's write speed? If you have an HDD instead of an SSD, that could be slowing things down significantly. You might want to check your storage device's specs to see if it’s the bottleneck here.
I just dealt with this issue on a family member's PC, where the speed was capped at 90 MB/s. Swapping the internet cable resolved the issue. It might not be your solution, but if you haven’t tried a new Ethernet cable yet, it could help!
9 Mbps is really low for your setup. You might want to check what type of coaxial cable is feeding your modem; older RG5 coax cables can slow things down. Also, signal splitters on the line can impact performance. Make sure you're using Cat5e or Cat6 Ethernet cables. If any of your cables only have 4 wires, it's time for a replacement. Corroded connections can also lead to problems, so try unscrewing and reseating any coaxial connections you can reach. If that doesn't help, it might be worth calling your ISP for a technician to take a look.
