Hi Mark,
Is the BB1 IP address really 192.1.168.233 or do you mean 192.168.1.233?
The difference is very important.
You should not need to alter IP addresses on the BB1. When you power up the BB1, it sends out a request to the router asking for an IP address. The router responds by sending a suitable address to the BB1. Then the connection is established.
John's query about the connection possibly being through a 'Guest' network is also relevant because 'Guest' connections don't work with BB1 or B2 units.
Can you tell us what your router IP address is?
Do you have any Wifi extenders in your network?
Regards,
Peter.
