Ah in that case its somethign else handing out the Ip addresses, connecting to 192.168.1.1 should give you some idea.   Try disconnecting everything else till this changes :)

@Philbert 

Good thinking. I recently added another device into the system (see photo) as it was spare. I added this to use as a switch for my telly, amplifier and virgin box downstairs in the living room.

To add and not confuse anyone. My tp-link switch is upstairs in the 'study' which connects all pc's, printers and home clouds.

That's now removed. Watch this space

Thanks again

@Philbert 

many thanks, Philbert.....

I regret to say that I get no IP Adress when I connect the Ethernet. The picture nI get is the following:

There is no signal coming out from the port, although the led is light.....

Doesn't look good , right?

Gracias

@Philbert 

By the way: this is what I get when I connect to the port of the router, which provides my with internet with no `problem:

Hey

Yeah think that gives you the answer, these things don't need any configuring so the fact you are not getting an IP address ... it would appear that yes sadly the device has failed. 

Only good thing is these are not expensive so you should be able to pick one up for around €20

@Nevian900 

Ah  OK that is a router and not a switch, it will hand out IP addresses to device and cause you issues

You could reconfigure it, but honestly just buy a cheap 5 port switch off amazon and that will save you any hassle.  

@Philbert  and @BTMJ 

I am finally sorted why my switch suddenly stopped working. The good news is my TL-SG1008D was not faulty. I put another router in the system, hoped to use it as a switch/hub. Which threw out new I.P addresses which confused me as much as the devices on the local network.

Thanks guys for your help, if you was local I would buy you drink. 

Next step is to buy a bigger switch as I need more ports. 

Thanks again. 

@Philbert 

very well....

many thanks!!!!
