I have been doing several tests per day for the last couple weeks on my PC. My download speed is slowing a little everyday. Testing over WiFi only all the same conditions and server, no network cable.. Of course my provider told me to use a different test site that gives me better results. I get good test results on my phones and pads using a different app called Net Analyzer. Now Im confused on what is more accurate. Has there been any changes to this program lately that may be having an effect on my results.
