- The WiFi device is too far away from the WAP to send or receive a radio signal.
- Tip: Most WAPs use a type of vertical omni-directional antenna that broadcasts a signal that would look like a big doughnut. Try pointing the antenna where the other wireless devices are located.
- The building structure (i.e. walls depending on their material) can prevent the signal from reaching the wireless device.
- Note: WiFi signals can be blocked by objects containing water (e.g. water heaters, fish tanks, water coolers, etc.)
- Electromagnetic interference from devices like microwave ovens or cordless phones all share the same frequency (2.4GHz) that is used by 802.11 networking.
- Too many other WAPs around the device, and they're causing interference.
