Hi jvallef,
The location where your wireless router and computer are placed affects the performance of your wireless network. To boost the wireless signal, it is ideal to place the wireless router either in the central part of your house or in a location free from any obstructions that may block its range.
You also need to make sure that the 2.4 GHz and 5 GHz have different network names to avoid interference. Interference happens if there is conflict with some wireless devices that are also using the same frequency within your network.
