What is a common cause of wireless clients experiencing slow speeds despite good signal strength?

Accepted Answer

RF interference or co-channel interference from neighboring APs on the same channel

Answer

Co-channel interference from APs operating on the same channel causes contention and retransmissions, degrading throughput even with strong signal.

Answer

The Client Health feature in Aruba Central shows per-client wireless metrics including signal strength, data rate, and error statistics.

Question 4

What does MTU mismatch between two network devices cause?

Accepted Answer

Large packets being fragmented or silently dropped, causing application-level failures

Answer

An MTU mismatch causes large packets to be fragmented or dropped by the device with the smaller MTU, often appearing as intermittent application failures.

Question 5

When an Aruba AP shows as Down in AirWave but is physically powered on, what should you check first?

Accepted Answer

Network connectivity between the AP and the management server (IP, VLAN, firewall rules)
