Recently my inernet has been working really slow.I checked my speed on speedtest.net and the results are-:
ping: 40ms
down:2.1Megabit/s
upload:0.5Megabit/s

but while browsing the pages take forever to load,the speed is around 100-200 kilobit/s and it jumps to 1.1
or 1.5 megabit/s for 1 second and then comes down again to 100-200Kbps.Also while downloading with idm the download speed is 50-60Megabyte/s whereas it should be around 256 Megabyte/s.

i use mozilla firefox for browsing and kaspersky 2016 as an antivirus
