Arris tg1672g issues - Time Warner Internet

I have 2 iPhones, an xbox, and a laptop that are contantly connected to my wifi, yet my laptop is the only one that drops signal pretty constantly. Sometimes ill go over an hour or so, sometimes a day or so, other times I disconnect 3-4 times an hour.

My drivers are all up to date, the router is directly under me in the house, ive tried disconnecting 5ghz and running only 2.4ghz, resetting the router etc etc and can't figure out what else to do. Im leaning towards it being a laptop issue (its from 2012) versus a router issue since no other devices flake out, but dont want to go buy a new one if its not required.

Does anyone have an possible solutions? I'm desperate here.
