I have a shed that's been converted into an office, and there is an ethernet cord that runs from my house to the shed. Here is the current setup that is working:
cable modem (in house)
wifi router (in house)
ethernet cable from wifi router to shed
I want to add another wired device in the shed so I bought this ethernet switch. When I connect the ethernet cable to the switch and then connect my computer via ethernet to the switch, I don't get an internet connection (all lights are blinking green for the ethernet ports however). The IP address also stays the same as when I use this device or when I connect directly to the ethernet cable (which I believe shouldn't happen).
What I can't figure out is when I connect the ethernet switch to my router using a different ethernet cable I do get an internet connection when connecting through the switch. The only difference in setups between the switch working and not working is the ethernet cable. Does it make sense that my ethernet cable to my shed has a successful internet connection but can't handle an ethernet switch (compared to a different ethernet cable which works correctly with the switch)?
Also, I have had a similar problem when trying to set up a router in the shed. When connecting an ethernet cable to that router, I still received no internet connection. I initially thought this was a problem with the router but after having the same problem with the ethernet switch I think it's caused by something else.
