Does it happen, for example, when a wireless phone handset is in use, or when a microwave is switched on? If you identify that a particular appliance is interfering with the signal, move the router away from the appliance that’s causing the problem. If you notice sudden increases in noise, try to identify when and why they occur. The narrower the gap between the two lines on the graph, the more unreliable the signal is likely to be. A reliable signal should have a signal strength of somewhere between -60 and -10dBm and a noise level below -75dBm. Both are shown as dBM, or Decibel-milliwatts, a commonly used unit of the absolute power of radio signals. The bottom graph, labelled Signal, displays both the signal strength and measured noise. If you notice frequent dips in the line, it’s likely that something is interfering with your Wi-Fi signal. Ideally, it should be a straightish line with small spikes.

The middle graph, labelled Quality, displays the ratio of signal to noise over time.

Move your Mac around and chart the signal strength in various locations to get an idea of where the signal is stronger and where’s it’s weak. NetSpot (free edition, or there’s a $49 Home version) to analyze the Wi-Fi signal in your building. If there is a lot of metal in the building that can also cause issues with your Wi-Fi, so it might be worth checking what materials were used in the construction of your property.

When we encountered this problem we had to update our Mac to the new version of macOS while sharing the internet connection from our mobile phone. This was a big issue in 2015 with the original version ofĮl Capitan (macOS 10.11): following the update, many users found their Macs could no longer connect to their wireless network.Īpple issued an update to the software, but this wasn’t an easy fix for MacBook Air owners who could only connect to the web via Wi-Fi due to the lack of an Ethernet port (unless they had an adapter). Updated their computers to a new version of macOS they have sometimes encountered Wi-Fi problems. We address problems with a weak Wi-Fi signal in a separate article here: You can jump to a guide to each of these steps by clicking the link above or just read through the steps in order below.
