Now, in fact, it's even funnier than this. After I disconnected gprs 
connection, just a few minutes ago, I restarted net by running netenv to 
change all the settings again. Now my /etc/network/interfaces is 

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
 
# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback
 
# automatically added when upgrading
auto eth0
 
iface eth0 inet static
address 150.217.140.158
netmask 255.255.255.0
gateway 150.217.140.1
network 150.217.140.0
broadcast 150.217.140.255

so, I believe, I should have the lo on again, but when I do route -n I get 

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use

and I seem to get only to my domain, not outside. 
Ifconfig says

so, both eth0 and lo are actually up, but lo has disappeared in the route 
table. And although the gateway and dns (resolv.conf is ok) are on the 
right values, I get just as far as my work group....I'm getting 
confused....what am I doing wrong?
