Major packet loss and disconnects

I’ve been having issues for about 2 months with my connection. Everything has been working fine since I moved in January up until now. Randomly throughout the night and day my internet will drop off completely for a few seconds then come back on. This is BOTH via Ethernet and WiFi. I’m a big online gamer and it’s hardwired to my PC and I’m the middle of a game, I’ll disconnect and then have to reconnect when the internet comes back 15 seconds later. Talk about annoying. 

I FINALLY got a tech to come after 2 weeks, he showed up and tested my cable at the demarc on the side of my house and inside. Stated it looked fine and ended up blaming router. (Xb8) 

Tech gave me new router and same issue. I don’t want to wait a whole 2 more weeks to get this problem resolved. I’m aggravated and just want to find out what’s wrong. 

I ran Ping Plotter app on my PC and you can literally see the packet loss. Also, what’s weird is that on hop 1, to my gateway (10.0.0.1) I get like 80% packet loss. It’s strange because it’s not only my Ethernet connection with issues tho. It’s strange tho because it’s my wireless devices as well. I’m just aggravated as I waited two weeks for a tech to come just for the problem to still be here. 

any help would be appreciated.
