Which steps are appropriate to troubleshoot intermittent Wi-Fi connectivity on a laptop?

• A. Check signal strength and channel, verify driver, test with different networks, update firmware on router/AP, disable power management on wireless adapter, ensure correct wireless standards (802.11ac/ax), check for interference.
• B. Replace the network card with a new laptop.
• C. Disable wireless adapter entirely.
• D. Only update the router firmware; ignore client drivers.

Answer: (A)

When troubleshooting intermittent Wi-Fi, a methodical approach that checks both the laptop and the network components and tests across different environments is essential. Start by looking at signal quality and channel use because a weak signal or a crowded channel often causes sporadic drops. Verifying the wireless driver on the laptop is important because a faulty or out-of-date driver can produce instability, so confirming the right driver version and updating if needed helps restore reliable behavior. Testing connectivity on different networks helps determine whether the problem is with the laptop itself or with a specific router/AP; if it disappears on another network, the issue is likely network-side. Updating router or access point firmware can fix known issues and improve stability on the network side. Disabling power management for the wireless adapter is a practical step because aggressive power-saving settings can cause the radio to disconnect or stutter during activity. Ensuring the device and the network use compatible wireless standards (such as 802.11ac or 802.11ax) avoids performance or compatibility problems that lead to intermittent connections. Finally, consider interference sources like other devices or neighboring networks that share the same channel, which can cause flakiness. This approach is preferable because it systematically addresses common causes (signal, drivers, firmware, power management, compatibility, interference) rather than acting on a single assumption. Replacing the network card would be unnecessary on a laptop that could be fixed with driver, power, or interference adjustments; disabling the wireless adapter would eliminate Wi-Fi entirely; focusing only on router firmware or ignoring client drivers would miss potential client-side issues.
