Fibre optic issue.. or new modem?

[wireless]

id say since i got home around 5:30 the 3-5 mins the only optik tv goes out on fibre... television signal has be lost.

i unplug the ONT and modem about four days ago. why is this happening, i thought only on copper would do this like at my moms place when she had copper.. now it like copper. should i check this out in the morning? is there a new modem or any new 4K set top boxes out this year?

...
