I have Comcast with an internet speed of up to 200 Mbps with most devices exceeding that by 20 to 40 Mbps. So such post as yours without providing details about your environment and equipment such as router model, wireless dongle exact model, distance and obstacles between pi and router are meaningless and no tips can be provided due to lack of detail. microwave oven (not a joke), RF mice, bluetooth, stb boxes and so on. Other environmental interference from all kind of devices which can only be seen with special equipment eg. N300 means 2t2r - 2 receive and 2 transmit streams with 40Mhz channel 'width', both router and client card needs to support them,Д«esides link speed of 300Mbps will give roughly around 150Mbps real network throughput in _good_ environmental conditions.Дistance and obstacles between client device and router.ДЄmount and signal strength of neighboring wireless APs - the more APs you have nearby the worse your results will be. Such as your wireless router hardware and software, some chips work together better than others. There are many factors which may (negatively) impact throughput. Wi-fi is not as simple as it seems to be. I just don't see anything glaring that would explain the low speed test. Some things I would like to know is if what I have done so far been correct. I have seen others with over 150 Mbps results using a wifi dongle so I know it's possible.

I am using Speedtest.cli to run the tests. Cyb3rgeek wrote:I have one Pi with the N300 dongle and the other two are using the onboard wifi.
