Final answer:
To improve Wi-Fi signal strength, a technician should reposition obstacles, switch Wi-Fi channels, adjust or upgrade antennas, or implement a Wi-Fi range booster. Testing with different antenna positions or boosters can demonstrate improvements in signal range.
Step-by-step explanation:
If a technician encounters a situation where the Wi-Fi signal strength is too low for the customer's needs, several steps can be taken to improve the situation. First, the technician should identify any physical obstacles that might be causing interference or signal attenuation, such as walls or large metal objects, and suggest changes to the network layout. It is also beneficial to check if the Wi-Fi channel is overcrowded and to switch to a less busy channel.
Another approach is to adjust the position and orientation of the router's antennas, or to upgrade to a more powerful antenna. If touching the antenna on a radio improves reception, this indicates that increasing the effective size or altering the orientation of the antenna could enhance signal quality. Similarly, for Wi-Fi, the length, position, and type of antenna can have a significant impact on signal reach and strength.
Finally, implementing a Wi-Fi range booster or repeater can extend the signal's reach by amplifying it from the main router. Testing the native range of routers and then using a Wi-Fi booster can quantitatively demonstrate the improvement in signal range. For more significant coverage gaps, a mesh network system may be considered, offering seamless coverage across larger areas.
