Good day! I am currently testing my access point (Tp-link TL-WA801ND) to get its actual bandwidth/throughput it can handle. I set up a PC (with prtg and file server) and the AP connected to my switch. I let wireless clients access the AP and download a test file from the file server. What I did was to keep adding wireless clients until the AP can't handle the max load. However, I got a weird graph on prtg with up and down graph. The graph can be shown here: http://postimg.org/image/s4iz4qjgl/ inside the red rectangle. Please help me analyze the graph and what's happening.
Here is the data on the specified time:
Date Time Traffic In (speed) 2/11/2015 3:31:00 PM - 3:32:00 PM 18,212 kbit/s 2/11/2015 3:32:00 PM - 3:33:00 PM 18,286 kbit/s 2/11/2015 3:33:00 PM - 3:34:00 PM 13,134 kbit/s 2/11/2015 3:34:00 PM - 3:35:00 PM 16,754 kbit/s 2/11/2015 3:35:00 PM - 3:36:00 PM 12,572 kbit/s 2/11/2015 3:36:00 PM - 3:37:00 PM 20,296 kbit/s 2/11/2015 3:37:00 PM - 3:38:00 PM 36,224 kbit/s
Between 3:33 - 3:36, I got up and down graph.
