For macOS, driver updates are typically included in the operating system updates. To check for updates, go to the Apple menu, select “About This Mac,” and click “Software Update.” If any updates are available, including those for your Wi-Fi adapter, install them. Note that macOS handles drivers in a more integrated way, so separate driver downloads are less common than on Windows.
What does it mean to “forget” a Wi-Fi network and how does it help?
“Forgetting” a Wi-Fi network essentially removes the saved network profile, including the password and security settings, from your device. This is helpful because stored network profiles can become corrupted or outdated, leading to connection problems. It forces your device to re-establish the connection from scratch.
When you reconnect after forgetting the network, your laptop will need to re-authenticate with the Wi-Fi network, ensuring it’s using the correct password and security protocols. This process often resolves issues caused by incorrect or conflicting settings saved in the original profile. It’s a simple but effective troubleshooting step.
How can I diagnose Wi-Fi problems using the Windows Network Troubleshooter?
The Windows Network Troubleshooter is a built-in diagnostic tool that can automatically detect and fix common Wi-Fi connection problems. To run it, right-click on the Wi-Fi icon in the system tray and select “Troubleshoot problems.” The troubleshooter will then scan your network connection and attempt to identify and resolve any issues.

While it may not solve every problem, it’s a good first step in diagnosing Wi-Fi connectivity issues and can provide valuable information for further troubleshooting.
What is an IP address and why is it important for Wi-Fi connectivity?
An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a network, including your laptop. It allows devices to communicate with each other and with the internet. Without a valid IP address, your laptop cannot send or receive data over the network.
Your laptop typically obtains an IP address automatically from your router using DHCP (Dynamic Host Configuration Protocol). If your laptop is not receiving a valid IP address, it may result in limited or no connectivity. Problems with DHCP or incorrect IP configurations can prevent your laptop from connecting to Wi-Fi, requiring troubleshooting steps like releasing and renewing your IP address.
My Wi-Fi connection is slow. What can I do to improve it?
Several factors can contribute to a slow Wi-Fi connection. Interference from other devices, distance from the router, and the number of devices connected to the network can all impact performance. Try moving closer to the router to reduce interference and improve signal strength. Consider also restarting your router to clear any temporary issues.
Another possible cause is network congestion. If many devices are simultaneously using the network, the available bandwidth is shared among them, resulting in slower speeds. Try closing bandwidth-intensive applications on other devices, such as streaming video or downloading large files. Finally, check if your router’s firmware is up to date, as updates often include performance improvements and bug fixes.
How do I check the Wi-Fi signal strength on my laptop?
On Windows, the Wi-Fi signal strength is displayed as a series of bars in the system tray, near the clock. Hovering your mouse over the Wi-Fi icon will show a more detailed numerical representation of the signal strength in decibel-milliwatts (dBm). A stronger signal will be closer to 0 dBm, while a weaker signal will be more negative (e.g., -80 dBm).
On macOS, you can check the Wi-Fi signal strength by holding down the Option (Alt) key and clicking on the Wi-Fi icon in the menu bar. This will display detailed information about your connection, including the signal strength expressed as RSSI (Received Signal Strength Indicator). Higher RSSI values indicate a stronger signal.
