Alright, this is a very "noob" question 😛 But suppose I am paying for a 5MB internet connection, and whenever I download anything I only get up to around 700KBPS at MOST. No matter where I download.
Why does this happen? Is it just me?
Pick a server to test that is closest to your location (your ISP may even have a server set up with them) and run the test. It will give you a result for your upstream and downstream bandwidth to compare with what your ISP is supposed to be providing you with. I do this periodically just to keep my ISP honest. Actually caught problems twice that way.
Check your computer connection sometimes it maybe the cause and try to re-start router and computer it will help boosting speed. Which close down the running programs on your computer and get bit more speed. Hope it helps!
