So many angry ADSL users, so many germans here. German made DSL modem tool should fit in here.
But what is DSL-Modem Tool and why do i need it?
It is tool that can view connection statistics, check line speed capabilities, manage modem/router and tweak some routers settings.
Many models are supported also many tweaks are available( for BCM63xx chipsets especially, I've managed to speed up connection at crappy line by 90% from 512 kbps to over 900 kbps is something by noisemargin tweak)
There are versions 1.xx to 9.xx. Don't go for 9.xx there are different version numbers for different hardware, not every modem in the world is supported, just check your modem type/router chipset.
