Wi-Fi is amazing, but it doesn't travel through buildings. The best way to connect two buildings is to dig a trench and run an Ethernet cable. However, this can be expensive depending on your budget and the distance.
Your next best option is a point-to-point wireless bridge system, which allows you to connect two buildings wirelessly. This setup is different from a mesh satellite Wi-Fi extender and requires some IT knowledge to install.
Please note that connectSCP doesn’t currently install or support services outside the structure where the ONT is located. You can purchase the necessary materials yourself or work with an IT contractor. YouTube can be a helpful resource for self-installation.
