Netgear Switch G5316v3
I setup a new home network and it worked for 3 mins then it stopped.
Nighthawk MS80 system Modem connected to Mesh Router which is connected to Netgear G5316V3 16 port unmanaged switch which i then connected to CAble Matters 24 port Shielded RJ45 Patch Panel. Currently only have 7 confimed working ethernet lines to 2 TV's, Xbox, 2 PC's. 1 not used.
When i set it all up and powered up, it all worked. Ethernet lines lasted about 5 mins then stopped.
The error msg being shown is there is no internet signal.
The wifi still works.However my ethernet cables no longer have internet signal.
The Switch lights are all blinking and power is on. When i power cycle the switch the internet does not come back, however all the ports are blinking like its sending data.
Is this Switch toast?

Not sure. This sounds like you might have accidentally set up an ethernet loop. That will briefly work, but after a short while there will be a flood that saturates the switch. Do you have any other switches?
So maybe start by disconnecting everything between the patch panel and the switch and reboot the switch. Reconnect one cable at a time (slowly) and see if that helps locate the problem connection.
