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.
- ✓Have a device ready that you can test the WiFi signal with (phone or laptop)
- ✓Know which room has the problem and which room works well
- ✓Check whether the wall between them is concrete block or drywall

Skip, I just want a technicianCommon mistakes to avoid
- Assuming the router is broken because one room doesn't work. Other rooms working proves the router is fine
- Adding a second router in the problem room without configuring it as an access point, which creates network conflicts
- Blocking the router's antennas with boxes or furniture. It needs open air to broadcast
Signs you need professional help
- If 2.4 GHz switching and router repositioning don't improve signal. If the room is critical for work and needs reliable coverage. If you want a MoCA adapter or permanent wired solution.
