I've experienced lag with gaming, this is shutting my internet down until I hard reset, occassionally it's just someone stressing my IP until the connection in the game cuts out but my internet is still up, just is very slow until they target someone else.
I've tested it by playing the same person who I know is booting me and it's just keeps on happening.
Buy a cheap router (eg TP-Link Archer C50), put the hub in modem mode. Use the ethernet ports on the C50. Then consider WHY you're being DOS'd and HOW your attacker knew your IP. If you can't keep your IP secret it will happen again, more so if you can't address the "why".
