Hi, everyone. I'm attempting (keyword attempting) to set up a home office/gaming setup type deal. The router I have has exactly ONE outgoing port, so I bought an Ethernet switch and hooked everything up. One PC? Wired connection works great, just fine. Other? Nada. Nothing. It feels like EVERYTHING has been exhausted trying to get this to work, and I have exacerbated the Ethernet switch's own basic and escalated customer service and troubleshooting, Windows customer service, my ISP's customer service, and even a close work friend who has been working in IT for almost a decade. None of them can figure it out. This has been an issue for over a week. I got so sick of this I drew a GRAPH in frustration to illustrate what it is I am trying to do. See "hELPME.png" below. Here is a comprehensive list of everything I have done to try to fix the issue: - Check and re-check my cables aren't damaged ( they are brand new, bought less than 2 weeks ago ) - Plugged said cables into different Ethernet ports on ALL devices. - Verified aforementioned cables work on different devices. They do. - Ran the whole "ipconfig - release - /flushdns" shtick. Twice. - Hard reset my entire network, starting at the modem and router by physically unplugging them and plugging them back in, device by device. - Physically cleaned all ports of any dust. - Updated and re-downloaded Ethernet and wi-fi drivers. I'm seriously at my wits end. I -need- this setup to work for my upcoming job or I'm gonna have to rescind my offer letter, my job requires a hardline connection. I will be actively monitoring replies and replying quickly, thank you to anyone who looks at this in advance.

Wow, you created a chart. Just to be sure, the PC’s wired setup functions properly, but only when one device is connected. Have you checked another switch—maybe a faulty one?

PC 1 functions correctly on any port, no issues with other connections. PC 2 fails to connect under all conditions.

Welcome to the discussions! To be precise, a "hard reset" usually refers to powering off and restarting everything, or reverting to original factory defaults, removing all settings before starting anew. Have you switched to a different network device? Is your managed switch configured to automatically assign IP addresses via DHCP?

PC2 may function on various networks, but it could be due to a faulty networking chip. Would your IT colleague have an extra Ethernet adapter they can share for testing?

Consider trying a fresh windows setup plus a BIOS reset. If it's connected to the network, you likely won't be able to detect it through pinging or the EERO dashboard.

Confirm your setup is managed and check if ports are uniform across VLANs.

I started from the beginning to rebuild the network. 2. I don’t own another network switch and funds are limited. This one was essential for it to function. I’m unsure how to set the managed switch to handle DHCP, since it was marketed as plug-and-play—just plug the cables in and it should work...

PC2 operates without cables on the Eero, wirelessly but not via a wired connection.

You're certain the ports match, but I'm unclear about what you're referring to with VLANs.
