Random disconnections experienced by users throughout an organization, without a clear pattern in terms of location or time, often point to interference as the primary culprit. Interference can stem from numerous sources like other wireless signals, electrical appliances, or structural features that impede signal strength or quality. Power level mismatches usually result in location-specific issues rather than random, widespread disconnections. Authentication errors would prevent users from initially connecting to the network, not typically causing random drop-offs. Bandwidth exhaustion would likely slow down the network performance for users rather than disconnect them entirely and would manifest more uniformly among users.
