WiFi dropping out after suspected Smart TV hack.

A few days ago I suspected my smart tv was hacked, so I disconnected my TV from Wifi, reset my router and a couple of devices. I also reset my wifi password and turned off WPS. 

Ever since my Wifi keeps disconnecting. The hub will turn purple, then flash orange for a minute or so then will turn blue and connect automatically again. It does this every 10-20 minutes at least.

I'm worried this is more hacking but trying to convince myself it's just a problem with the hub since it's been reset. 

We have had issues with internet dropping out in the past, but not so persistent and as continuous as this. And this happening after the Smart TV problem has also intensified the worry over the connection issues.

Could these issues be caused by something like this?

if your hub is flashing orange then back to normal blue that is not a wifi problem but a hub internet connection problem.  you need to check your internet connection and if on fibre to cabinet copper to home - FTTC  then check master socket and possibly use test socket to see if that helps
