Hello, I have a 2,5mbit service at my ISP but suddenly 1 month ago speed dropped from 250kb/s to max 30kb/s. Now the ironic thing is my ISP tells me its a local problem even though I´ve tried it on 3 different computers witch 3 different networks cards without any result, and since speedtests are showing the correct speed it cant be nothing wrong on the TP-Cable. It sounds weird I know but does anyone have any suggestion as to what the problem might be?
