Amazon has a great deal on a home Mesh WiFi System in the AmpliFi HD. This is typically around $349, but right now it is on sale for just $249.
A mesh WiFi system like the AmpliFi HD is a great purchase, whether its for yourself or someone on your shopping list this holiday season. It'll provide you with more coverage on your home network, but also with faster speeds throughout your home. Think of it as a signal extender or signal repeater but without the quality of the network being degraded for better coverage. It does support both 2.4GHz and 5GHz WiFi networks, so you'll get fast speeds, and it'll cover most mid-sized homes. It might be overkill for an apartment, but it's still nice to have that extended coverage available to your fingertips.
