Go deep into RF: Understand RSSI, SNR, noise floor, interference, channel utilization, attenuation and common reasons for wireless performance degradation.
Practice troubleshooting: Take scenarios such as “client cannot connect,” “roaming fails,” “high latency” or “low throughput” and explain your investigation step-by-step.
Revise Linux: Practice ip, ss, tcpdump, ping, traceroute, ethtool, iw and log-analysis techniques.
Know packet analysis: Be comfortable identifying DHCP, DNS, ARP, TCP and wireless-related issues through packet captures.
Prepare lab scenarios: Be ready to design a scalable enterprise topology containing APs, switches, controllers/cloud components, clients and traffic generators.
Think like a feature owner: Explain how you convert requirements into test scenarios, define coverage, reproduce defects and communicate findings to development and field teams.
