Hi Iain,
Looking at your first post, I see that your B2 IP address is showing as 168.195.1.95. This is somewhat unusual. Normally the address range will be 192.168.x.y where x will be 0 or 1 or 2 and y can be any number, usually betweeen 2 and 253.
When the B2 starts up, it initiates a connection request to a router (either wired or wireless) for an IP address. The router responds by sending an IP address to the B2 (from the router's IP address table). The IP addressing is controlled by the router.
Can you log into your router's 'admin' page to look at the router's IP setup? If so, what IP address do you use to connect from your PC into the router. Also, can you post the make and model of your router, so that I can look at the router's manual.
The Brennan devices are normally very good at connecting to routers, and most of the connection issues are down to router and network problems, so don't give up yet!
Regards,
Peter.
