I have TWC for internet and a Netgear router (roughly 6yrs old). I have a basic kindle, nokia cell with wifi calling, roku and Mac laptop. Laptop keeps dropping connection and then I have trouble re-connecting. Network either doesn't show up or the address doesn't send. Other devices will connect w/o any problem. Do I need a new router? Is something wrong with my computer? TWC says nothing wrong with signal. I'm a bit of a tech idiot so plain language is very much appreciated. Thanks!
