You haven't specified your Blackberry OS in your profile so it is difficult to be specific, but modern Blackberry OSs are designed to work with, and use Wi-Fi in conjunction with, a Blackberry Data Plan. You can use it without one, but it can be problematic as you are finding out.
Thanks for the response.
I've checked Wi-Fi diagonstics (Options > WiFi Connections > *WiFi profile name* (not the actual profile name obviosuly) > Wi-Fi Diagnostics). That's how I got to it, I'm assuming more/less we're on the same page there.
I have Blackberry OS 4.5.
I've also removed the battery several times.
Again I have had success twice in getting WiFi. The first time was the evening I bought the router on Sunday (just needed to get the MAC address settings proper), and the 2nd time was 2 days ago with just a battery removal.
The error I always get is UMA 004 which means it doesn't establish an IP/DNS connection at all (I think more/less).
I had no trouble at all connecting to my previous router via BlackBerry WiFi (before that router kicked the bucket this weekend).
