So I am gonna get this router , right off the bat I need to tell you guys that I am literally brainless when it comes to network things and stuff in this category , I currently have a router/modem from my current Internet Provider (Spectrum) I am getting good internet speeds but I do get really slow speeds when in rooms around my house which makes sense but I am wondering if this router will help me with improving this issue & what benefits I'm getting with this router. current router (TECHNICOLOR TC8715D) not sure if this router im getting will bottleneck it!
