First, consider your internet plan. 4K works best with a minimum speed of 25 Mbps. If your plan is slower than this, you should consider upgrading. Next, consider your router. To prevent throttling, you’ll want a router that at least matches your internet plan speed — but ideally, you want a router that supports speeds faster than your current plan. For best results, look for routers that support beamforming and have a wider coverage range — or invest in an extender to create a mesh network. Then, consider switching streaming devices like televisions and gaming consoles to an ethernet connection which is faster and more stable than wireless connections.
