No internet after switch is plugged in
I have a GS305v3 unmanaged switch that I just bought and attempted to use. It is connected to my internet via cat6 cable that I ran from my office in my house where my router/modem is located, to my bedroom. When I connect any device to the ethernet port that I put in the bedroom, I have no issues connecting to the internet. But if I plug the switch into the port, then any device to the switch, no internet is passing through. All lights on the switch illuminate as they should according to the manual, but I can't seem to find any info as to what the problem possibly is. For a clear picture of how all the hardware is set up:
Fiber internet direct to router/modem in office
Cat6 cable to ethernet port in office
Cat6 cable from office ethernet port to bedroom ethernet port through the attic
Any device connected directly to ethernet port in bedroom works perfectly with 1000mbps+ download
Switch plugged direct to ethernet port, devices plugged into switch, no internet to any devices
Any advice would be greatly appreciated and thank you in advance to anyone who offers advice.

I'd start by putting the switch in the office, and seeing if it works there.
I will try this when I get back home this evening. If the switch still does not work, am I looking at a bad switch?

Either a bad switch, or an incompatibility between the switch and the Eero multigig LAN ports.
Try both the 2.5 and the 10gb ports on the eero, as they might behave differently.

The GS305v3 is physically connected by cable to a LAN port on the router, where private RFC 1918 Addresses are issued by the DHCP server?
What typically cant work is an Ethernet connection to a ISP -modem- where one or a handful of public IP addresses are assigned to the clients on the LAN - these are intended to connect a NAT router only. Do the devices connected to the GS305v3 get warnings of no Internet connection? This would be a a clear indication a change in the cabling (in your office) from the network port on the wall to the router LAN port is required.
They connect perfectly if I plug them in directly to the LAN port in my bedroom. But if I connect my switch to the LAN port and a device to the switch, the device is not receiving any internet connection.
And yes, the LAN port is connected through cat6 from the router, that LAN port is connected to a LAN port in my bedroom via cat6 cable.

As schumaku says, the switch needs to be connected to a router's LAN port.
But many "modems" are actually gateways (modem+router combined).
When you say "router/modem" are you talking about one device? Or two?
If one, then what is the model of the "router/modem"? That would help us understand what you have.
It is an Eero Max 7. When I looked into specifications for it, it appears to only be a router. I'm not super tech savvy, so I may be misinterpreting what I read on the eero website about the product.
It is an Eero Max 7.
It is wifi-7 mesh system (router+satellites). Not a modem.
What wifi performance are you getting in the bedroom?
One option is to connect the ethernet directly to an Eero Satellite in the bedroom, and see if that works That would give you a faster connection than you'll get with the switch (since the Eero has 2.5 gb and 10 gb ethernet). Then connect the PC either with WiFi or ethernet to the satellite.
So the 60ft cable plugs into the backside of each port, then another cat6 cable is connected to the outside of the ports to run to devices
Something like this?

Whenever I read "ran my own cable", I get suspicious of the cable connectors. Did you connect your own ends? Some devices are more sensitive to sketchy cables than others. And even a wire tester won't pick it up becuase its just passing a current, not data. So I'd follow what StephenB recommends and try the switch right by the router with a different cable. If it works there, time to check the cable ends for how they were terminated.

Me too, which is why I suggested testing the switch in the same room of as the modem/router.
This particular switch supports energy-efficient ethernet, which might not work correctly with Staggs0226's particular cable (including the connectors).
FWIW, insulation on cables designed for in-wall use is different from normal patch cable - often building codes require plenum-grade or riser-grade cable. That doesn't affect performance, but using a normal patch cable can create fire safety issues.

Myths and legends? Sorry, this is pure nenesense !
The cable is a pre-made 60ft cable rated for outdoor use that I ordered. I haven't had a chance to test the switch in my office where the router is due to me being out of town. But if other devices get connection with no issues on the same cable, wouldn't that be an indication that the cable is good?
No, I did not connect my own ends. It was a 60ft pre-made cable rated for outdoor use(figured this would be best do to the extreme heat that build in my attic living in Texas) the LAN ports in both rooms are female to female.

To update on the router for more specifics, it is an Eero Max 7. When I looked up the specs for it, it appears to be a router only with 4 ethernet ports, 1 being used for the connection to the modem, a second port is where I connected the cat 6 cable that runs to the LAN port in my office, linking it to my bedroom
With a GS305v3 direct connected to one of the Eero 7 LAN ports, things should work as expected.
If not, that might be a reason for talking to the Eero support - as this looks to me like a perfect simple and straightforward configuration. Even if there is one of more Eero system using the switch as a part of a wired backhaul.
Your Eero 7 is operating at the current Eero firmware?
