Hi all,

My first post in spite of having owned TP-Link hardware for several trouble-free years!

The story......our new house extension is a long way from the wifi router so we put in a wired connection from one of the main router output ethernet ports.

At the other end, in the new extension, I have 3 devices competing for one ethernet port:
1. A TP Link router to create a wifi hotspot.
2. A smart TV
3. A set top box.

All of these devices have worked perfectly when individually plugged into the ethernet socket.

So I bought a TL-SF1005D thinking it would solve my problem.

The basic setup is ADSL line > modem > main router > ethernet wire/socket > TL-SF1005D then a cable in ports 3, 4 and 5 to each of the three devices.

The result is:
1) The mini-router is working perfectly giving me wifi (using it to submit this thread) - connected via the switch.
2) Smart TV will not connect
3) set top box will not connect.

I've re-booted everything several times with no result. Given that one device is working and the other two are not, I'm stumped. And I'm very non-technical. This is meant to be plug and play.

Any ideas?
