CCNA Discovery 1, Chapter 9

9.3.4 and 9.3.5: Connectivity problems on a WLAN can occur because of authentication issues, interference, signal strength, standards mismatches, and bandwidth issues. Consider the following points when troubleshooting a WLAN:

Standards: The client or AP may be using incompatible standards such as 802.11a on the 5-GHz frequency and 802.11b on the 2.4-GHz frequency.

Channels: Overlapping channels for conversations between devices may be affecting connectivity.

Signal: A lower-strength signal may cause a connection to periodically drop and/or become unreliable. In addition, outside sources such as wireless devices not associated with the WLAN may be interfering with the signal.

Bandwidth: An increase in users or high bandwidth utilization may affect network performance. You can monitor traffic and identify users or applications that hog bandwidth and deal with them professionally, personally, and possibly technically.
