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 ...

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.

There are (or maybe were) some chipsets that go beyond the standard, and set the power level based on a cable length estimate, and also put the link in standby status when it thinks the link is not in use.
No idea if this particular switch includes those extra features.
I have sometimes seen issues with this tech, which were resolved on managed switches by turning this feature off.

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. 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
