Hey all..long time no see.

Some people I work for (yard work, etc) have BellSouth ADSL (supposed to be connected through a modem/router..but that never worked, and I don't know enough to set it up/fix it..so I put their USB modem back in, which used to work)..the modem syncs with the server and connects without a problem (dialup networking connection)..sits there saying it's connected, but it's dead. No websites work -- can't ping from MSDOS window either; tried both a URL and an IP (in case DNS was messed up). Any ideas?
