Legend can't connect via wifi

---

Having problems connecting to a Belkin wifi adsl router with a Legend I bought for my wife. My Desire connects with no problems.

wifi analyser showing 70dBm, no other wireless routers in the area using the channel.
using wpa/wpa2 psk, router is in the same room.
I get prompted to enter the passcode, then nothing. Wifi shows as disconnected.
No wifi strength meter showing in the notification bar and no connection attempts showing at the router.

Are there any log files on the phone I can check?
I'm new to android so any hints would be cool.

UPDATE:::
Rebooted router, wifi now working..
Strange!

Thanks
