I am adding a room on top of our garage that is opposite of where our router sits in our home. What are my options to access my network from this new area?
The way to access it is exactly the same. Just be advised that the signal /reception may not be as good / strong as other areas are. Also, depending on the conditions, there is a chance that there may be no reception at all. If that is the case, or the signal is too weak, a WiFi booster / extender may be needed.
