New iMac wireless problems

[ajf]

New iMac keeps dropping the wireless connection.
Power save turned off.
Sometimes it shows as full signal but will not connect to web etc.
other times it completely looses the wireless network and cannot see it, or sees it and refuses to connect and keeps requesting WPA2 key.

Router is a Belkin N+ and works fine with three Vista and Win7 laptops.
It is set to use B,G and N wireless.

I have deleted the network on the Mac and added manually and all updates through software update have been installed.

Any other ideas beyond hardware issue? I really don't want to have to take it back Might resort to wired connection....

Other than this though Mac experience going well

Does your router have the ability to do 5GHz?

Is it close to the router?

Turn on robustness?

Hi.
No, although it is N, the router only uses 2.4GHz bands. I have tried changing the channels - think it's on 9 at present.
It is about 4 feet from the router which is the other side of a wall on a shelf. I actually tried moving it AWAY in case it was too close given the height of the router.

Not sure about robustness, but the router has QOS on if that is the Same?
