Shopping List
Below is a list of common items that people have asked for recommendations on, these are all items that personally use.
Router
I have been using the Synology RT2600ac for about 8 years now and have installed it for a few family members over the years without any issues.
Keyboard and Mice
If you're willing to spend the money, go with the Logitech MX Master Series, if you're on a budget go with the Logitech MK955 combo.
