WiFi Signal Strength

Distance from your wireless access point is not the only factor in determining signal strength, for example, many older homes, including ours, have plaster walls constructed on a metallic mesh that serves as its framework, and this metal can cause extra signal loss.  To solve this, I have a 5+ year-old Netgear N150 Range Extender plugged into an outlet in the kitchen that has a direct line-of-sight to my router, and that helps get coverage to the backyard patio.  The image on the left below, using the free (I love free) OpenSignal app, shows a weak signal for my primary WiFi network from the patio, but switching to the Range Extender (with the _EXT suffix on the right), gets us back to a strong signal.
