[Trisquel-users] DSL modem

[mono]

Hallo,

am very happily running free software on three computers (trisquel and  
parabola)

now, am wondering about my internet connection. am using a proprietary device  
which includes a DSL modem for connection to ISP, a router and a WLAN access  
point. who knows what this device is doing (other that providing internet  
connection)?

my question:  Is there any device existing, old or new, that can replace the  
proprietary device by running 100% free software? The most required  
functionality is that of the DSL modem connecting to a line with standard  
ADSL2+

cheers,
Mono
