On initial load or refresh of the 2.2 UI, the Average Wireless Throughput plot initially spikes to a very high mbps value (between 1k and 40k mbps). This makes it difficult to see the actual throughput on the graph until the spike clears the graph over time. Refreshing the page causes another spike, again, making the graph unusable. This issue happens on both Chrome Version 37.0.2062.124 m, and FireFox 29.0.1. This also has happened on multiple computers.
Hi,
This is known bug and we will be addressing it in a near future release. Sorry for the trouble its causing. Like you said, the graph will settle down after 30-60 seconds.
