Don’t forget your DNS entries
If you’re able to connect to the Internet but can’t pull up any Web pages successfully, the problem is almost certainly missing Domain Name Server (DNS) entries. Without a DNS server, the browser can’t resolve the names of Web sites into their actual IP addresses. This is the same in BeOS as it is in all operating systems. Obtain a pair of DNS server addresses from your ISP and enter them into the fields in the Dial-Up Networking panel. Similarly, if you’re using a network interface card for your connectivity, you’ll need to enter DNS entries in the Network preferences panel.
Restart networking and you’ll be good to go. Note that you may need to restart NetPositive as well.
