Hi I hooked up a simple Netgear switch to allow me to run lines to each of my optic boxes and to wifi boosters. When I turned it all on my whole system when down - no wifi, no tv - nothing - wife n...

It seems like it was sending some signal - at least for a while. I ordered a dongle to try it with my laptop. What do I look for? How do I test it?
Just get another switch?
Thanks
I read that for some switches at least you need to restart the router after connecting. True?
Perhaps for managed switches but I've never needed to do that for unmanaged switches.
Connecting cables to the switch with nothing on the other end will do nothing. If the cables are good then it's the same and having nothing plugged in as far as the switch is concerned. The only time it would make difference is if the cable is shorted. It's best to do the test with just the cable to the router and the cable to the Optik box.
When you got the |Internet signal lost" message what was the state of the port LED lights on the switch (both to the Optik box and the router)?
Is the switch new or old? While it's possible the switch is bad it's more likely the power adapter might be bad. I've had to replace a power supply on my Asus switch because it was buzzing. While it still worked at the time any noise from an power adapter is a sign of impending failure.
Thanks
The switch is brand new. I didn't look to see what the lights said when the tv went out - I'll try again.
I didn't hear anything from the power supply.
- I tried again. Same thing. Tv stops getting signal. Both lights, were I have the cable to the tv and the one to the Optik box, both blink green.
It works fine when I bypass the switch and hook the Optik Ethernet directly to the modem.
I’ll try another switch.
