You might not need to buy a new router if you can fix the interference problems you're suffering.

The newest measurement will always be at the top of the graph.How to detect and fix Wi-Fi interference Fixing interference Blue representing low noise, and red indicating high noise.Īs more data is collected, trends can be seen as color bands develop over frequencies with higher average noise levels. Each second, a new line will appear on the top of the graph, color-coded based on noise level (utilization). The second graph section on the page displays the same information, but providing snapshots of each measurements over time. The image below shows a result of this after about 2 minutes. Thus over time, the red area of the graph can represent the average/typical channel utilization, while blue represents less frequent values. Points on the graph will move from blue to red as more measurements match that point. Over time, as more measurements are taken, a more colorful graph will develop.

The current reading will be indicated by a thin white line. This graph will start largely empty, and continually update with new readings. Lower values are better (like -100dBm), keeping in mind the numbers are negative. The next section of the page will display a spectrogram of utilization on each channel. If using as part of channel planning, measurements are best taken when no SSIDs are active on the AP While this is to be expected, it can still be used as an indicator that a particular AP or channel may have too many clients. When monitoring channel utilization and reviewing the information below, it is important to remember that a busy wireless network will naturally result in higher utilization of channels. If there are none within the selected network, the page will not appear. Only APs (Access Points) with a dedicated WIPS radio will appear on this page. To access this information, navigate to the Monitor > RF spectrum page. This information can be useful when troubleshooting wireless issues or determining which channels to use in high-density environments. Cisco Meraki access points with a dedicated WIPS (Air Marshal) radio, such as the MR18, MR34, or newer (excluding MR20 and MR70) have the ability to do real-time spectrum analysis of their environment while still serving clients.
