Pigging WIFI........

I can not use DHCP on my router. So I need to manually enter my WIFI settings.
My router shows up fine when I scan. However after manually entering all the correct IP addresses and pass key my 8900 still won't authenticate and checking the settings shows device IP address as 0.0.0.0
It doesn't seem to be saving the manually entered IP address.
When I check the network settings, the IP address is entered correctly and the rest of the details are all fine. When I try to ping 'self' it shows IP address as 0.0.0.0

Is this at home or at work? Any home router can be configured to use DHCP.
If at work, you have no idea how its configured and are pizzing in the wind.

Good luck trying to enter IP info into a BB and praying it all works.
