Broadband (ADSL)

What kind of modem it is?

I use a (wired) D-Link Modem + Router (Model no: DSL-2520U). This is 
hooked to the box's [Ethernet Controller][1] through a RJ45 cable.

[Ethernet Controller][1]: Here is a description of the controller, that 
I picked from the "lspci -knn" command.

FYI, I use Linux-Libre-3.6.8 kernel.

What follows is the output of commands, when the modem is tethered to 
the internet, _after booting the computer_.

Note: The computer was not getting connected to the internet, when these 
outputs were taken, though the modem's lights suggested that it was, 
indeed, connected to the Internet.

[   68.153997] r8169 0000:02:00.0: eth0: link up
[   68.154025] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Period.

Observation:

 --> When do the "route -n" command, 5-6minutes after the _modem_ is 
tethered to the Internet, I get this:

address@hidden:~# route -n
Kernel IP
Destination  Gateway      Genmask         Flags Metric Ref  Use Iface
0.0.0.0      192.168.1.1  0.0.0.0         UG    0      0      0 eth0
192.168.1.0  0.0.0.0      255.255.255.0   U     0      0      0 eth0

Now, my computer is able to connect to the Internet.

 --> It takes, the computer, 5-6mins longer to connect to the Internet 
after the modem has been tethered to the Internet.

What can be done to remove this delay? Is it possible at all?

I thank you.
