What action can be taken to troubleshoot low signal strength?

Moving closer to the source is an effective action to troubleshoot low signal strength. By reducing the distance between your device and the source of the signal, such as a wireless router or access point, you increase the signal strength received by your device. Radio signals naturally weaken over distance, so proximity can significantly enhance connectivity and overall performance. This method is particularly useful in scenarios where physical barriers or obstructions are impacting signal quality.

The other options may not yield the desired improvement in signal strength. For instance, reducing transmission power would diminish the range of the signal, worsening the issue. Decreasing antenna size could likewise lead to a reduction in signal reception capability, as smaller antennas typically have a limited range compared to larger ones. Disconnecting unused devices might alleviate network congestion or reduce interference but would not directly improve signal strength. Thus, moving closer to the source is the most straightforward and effective approach in this context.
