can you ping ( now ) 
206.176.148.90 
this is the address on the other end of your PPP connection. 

If you re-connect and get a different 
"inet addr:207.53.228.68  P-t-P:206.176.148.90 Mask:255.255.255.255"
line... the try and ping your new P-t-P address.. This is your gateway
at your ISP. If you can't ping it...then you probably can't ping anyone.
Also... make SURE and use -n on your ping... you don't want to do 
name lookups if your having connection problems. Some times ping 
will fail because you can't resolve the name.... 

also... use something like 
mtr -n 216.109.118.78 and see what that shows you. this is a 
traceroute program that I find pretty useful.
