WiFi works in one room but not another

Something between those rooms is blocking the signal. Concrete walls block WiFi far more than drywall. The fastest fix is switching to the 2.4 GHz band, which penetrates walls better than 5 GHz.

WiFi signal gets weaker the more walls it passes through. Concrete block walls cut the range almost in half compared to drywall. When your router is on one side of a concrete wall and you're on the other, the signal can fade to nothing. The good news is multiple ways can fix it, starting with switching wireless bands.
