Hello, your description gives a clear picture. I have seven other workstations connected via a 400 Mbps link through spectrum. All PCs in the office performed over 280 Mbps except one. I've tested various cables, wall adapters, switches, and even used a USB to LAN adapter. Software adjustments were also attempted, such as boosting speed and duplex to 1 gigabit, uninstalling and reinstalling drivers, disabling and re-enabling them, restarting the PC, and checking Wi-Fi connectivity (which failed). The PC is an Inspiron 3670 by Dell with an i3-8100 CPU and no GPU. I couldn't find any motherboard details, but after testing a second LAN switch, I suspect the issue isn’t hardware-related anymore. I’m running out of ideas and don’t know what to do next.
I’d try to link this PC straight to the router or main networking switch in the office server room to confirm it’s not just an ethernet cable or wall jack connection. Since I’m unsure about your setup, please note I might have already tested this or you may not have a server room. I’m only suggesting alternatives for situations where speeds differ between devices.
I connected it to the router earlier but it didn’t work. I’ve also relocated this PC to different desks with functional ports and cables, and moved devices with proper connections to the areas where the original PC struggled. The working computers kept functioning even when using any mix of cords, switches, and ports, while the one that didn’t connect well remained unreliable no matter the setup.
Is SmartByte operational? If yes, attempt the tests without it enabled.
I really care about you. Smartbyte did it. The computer is now handling 350 mbps. That's incredible!
