I live in university halls and only have access to the internet and the network through one ethernet port. I have a TP-Link R860 router (wired only) and a TP-Link simple switch.

If I connect using the simple switch, one device can access the internet and all the other devices on the switch. If I use the router, everything can access the internet, but cannot access each other on the subnet.

How can I connect all my devices so that they can all access each other as well as the internet?

Thanks!

Sounds like your router may have the mode turned on which isolates the clients from being able to talk to each other. This is a common setting you can turn on on wifi access points.

I assume the router is a dhcp server and is doing NAT?
