MacBook Won‘t Connect to WiFi? 12 Fixes to Try in 2024

Hey there, fellow MacBook user! Is your MacBook refusing to connect to WiFi, leaving you frustrated and disconnected? Don‘t worry; you‘re not alone. According to a survey conducted by MacWorld, 37% of MacBook users have experienced WiFi connectivity issues at least once in the past year (source: MacWorld, 2023). As someone who has been using and troubleshooting Macs for over a decade, I‘ve encountered my fair share of WiFi woes. In this comprehensive guide, I‘ll walk you through 12 effective fixes to get your MacBook connected to WiFi and back in action.

Why Is My MacBook Not Connecting to WiFi?

Before we dive into the solutions, let‘s take a quick look at some common reasons why your MacBook might not be connecting to WiFi:

1. Weak WiFi signal or out of range
2. Incorrect network settings or corrupted network preferences
3. Outdated or buggy WiFi driver
4. Hardware issues with the WiFi card or antenna
5. Interference from other devices or networks
6. macOS software glitches or bugs

Did you know? According to a report by OpenSignal, the average WiFi download speed in the United States is 30.3 Mbps, while the average upload speed is 10.3 Mbps (source: OpenSignal, 2021). If your MacBook is experiencing slower speeds, it could be a sign of WiFi connectivity issues.

The Evolution of WiFi Standards and MacBook Connectivity

Over the years, WiFi standards have evolved to offer faster speeds and better connectivity. Here‘s a quick overview of the most common WiFi standards and their maximum theoretical speeds:

WiFi Standard	Maximum Theoretical Speed
802.11a	54 Mbps
802.11b	11 Mbps
802.11g	54 Mbps
802.11n	600 Mbps
802.11ac	1300 Mbps
802.11ax (WiFi 6)	9608 Mbps
