Hi Marek Buras,
What kind of connection do you have?
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.
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 02)
Subsystem: Giga-byte Technology GA-EP45-DS5 Motherboard [1458:e000]
Kernel driver in use: r8169
Kernel modules: r8169
FYI, I use Linux-Libre-3.6.8 kernel.
Output of those commands:
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.

I think you should check if you can reach your gateway and primary/secondary
DNS servers (listed in /etc/resolv.conf) too.
address@hidden:~# cat /etc/resolv.conf
nameserver 192.168.1.1
Maybe there are some error
messages in /var/log/dmesg related to your modem?
[ 68.153997] r8169 0000:02:00.0: eth0: link up
[ 68.154025] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 84.870983] r8169 0000:02:00.0: eth0: link down
[ 86.535358] r8169 0000:02:00.0: eth0: link up
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.
