As Mauricio said you must be in the same network that the DSL modem:

Some considerations:

I assume this is an Ethernet one and not USB one, right?

Which IP are you trying to access?

What is the computer IP and netmask?

Did you tried to connect the MODEM directly to computer and set the IP
to DHCP? Then look the IP you got and the gateway ( ip address show |
grep -i "inet\ " **OR** ifconfig |grep -i "inet\ " ) and the default
gateway ( ip route show | grep -i default )

The "usual" would be you try to access the MODEM in your gateway
address, but may be other.

The maker and model of MODEM would be great

Good luck
