Problem with LAN connection speed Issue affecting network performance
Hi, I'm new to the forum so i'm not sure if I posted in the right place. I have 2 threadripper pcs with an aorus x399 pro motherboard. The onboard lan is gigabit and I also have 2 pcie gigabit network cards from intel. If i go to ethernet adapter, the link speed is shown as 1 Gbps and I also have two 1 Gbps connections from my internet provider. The problem is that in speedtests and when transferring files through lan the speed is actually 100 mbps. The speed doesnt go above 10-12 MO/s. I tried with both, the onboard lan and the other network cards that I have. They all show 1 Gbps in adapter and in NIC settings in windows but the speeds are actually at 100. If i go into bios in the network adapter NIC settings, there isn't an option for 1 Gbps full-duplex, only up to 100 Mbps full-duplex. Can it be that it is a motherboard problem and it's limiting the speeds? There isn't any bios update and I don't know what else to do at this point. Cables are cat 6e, the switch is gigabit, the router gigabit, connection gigabit, I have tried with multiple equipments and I can't find the cause behind that setting in the mobo bios. Any help is highly appreciated!
Verify the actual connector, confirm those eight pins are present—no shorts and no overlapping pins. Test the internal pins of the connector by gently pressing each one with a toothpick or similar tool. Repeat this on your switch or router as well. Inspect the cable, switch to a different one if needed. Keep in mind that 1 Gbps equals roughly 125 MB/s. If the network card shows 1 Gbps in its properties, it should connect to another device at that speed, meaning you should see over 100 Mbps. Be aware of any antivirus or firewall software that might interfere with data transfer speeds.
Disabled any form of antivirus and firewall. I'll check the pins and see if it works when I get to work but they should be fine, I checked with at least 6 cables new and old and it's the same. All the other pcs are fine and they transfer at about 120 MO/s only those new ones act like this. I'll also try to contact aorus and see if it's actually bios related but I doubt that I'll have any luck with them
It seems like the problem might be related to the BIOS component. I'm not sure why it's happening, but I think it's connected to the BIOS. Aorus should provide a clear answer.
