@avagreen presumably your flat has walls? If so and these walls are solid not plasterboard  partitions they will cause signal loss. Small,flats can often be more of an issue than large open plan homes as internal walls can be made of concrete in many blocks. Another issue with flats is they have many neighbours whose WiFi networks can cause interference.
