I am concerned about my internet. I have been living here for over 2 years now and have no problem with my provider LIVE TIM. However, I have had issues with certain functions when I work from home. My job shows issues with my connection to a voice over phone system. I also stream to Twitch.Tv video games sometime and notice some slowness...my speedtest.net always shows a range of 20-30MBS Download and 15-20ish UPLOAD.
However, anytime I used testmy.net i NEVER break 5mb up or down. What do I trust? What can I do to improve?! What detailed tests should I do to show the proof to my ISP? Thanks for the help in advance. For everyday browsing I never feel a slowdown for downloading or browsing. Its just very specific items such as Streaming, sometimes my PS4 connection is slow wired and wireless etc. No matter when i test though these results are always the same.
