said by mirjahan :I have a question why i can not get proper adsl2+ speed?
I live 1.5 km from colbanet/bell co by walking distance so with that distance i should get around 18-20 mbps of 24 mbps.
If count bell copper line distance from bell co could be 3km from bell co so in that point i can get 8-10 mbps of 24 mbps.
As my modem Netgear DGN2200 adsl2+ modem line attentunation is 46.5 db and that i should get around 5-7 mbps of 24mbps.
But but adsl2+ modem connect on 3.7 mbps not my expect speed by line atentunation around 5-7 mbps but i get only 3.6mbps.
Please answer
1.5km walking distance is not necessarily your actual wire distance. Wires loop around streets and neighbourhoods. Your 46.5 db attenuation reflects that you are much farther than 1.5km.
There are also other factors than just distance, the quality of the line, the gauge of the wire that is used by bell to run to the CO, etc...
There is nothing scientific about the numbers, there are too many variables.
