Hardware Network problem with wireless connection

[Qtis]

Hi all,

I've been trying to get my 360 to connect to live for a few game patches/updates. Unfortunately I can't seem to be able to connect to the wireless (Apple Airport Express, 1st gen). The connection is found and it works flawlessly with my PS3, printer, laptop, etc. It's broadcasting a/b/g/draft n (The AirPort Express Base Station is based on an IEEE 802.11n draft specification and is compatible with IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g.) single band at 2.4 GHz.

Any ideas how to fix it?

EDIT: Brand new Halo 4 LE 360 in question.

Try clearing the systems cache (you will lose all other TU's)
Then set up a new connection.

I have no experience with apple stuff anyways but theoretically it should be the same.

Edit: found something that might be of use here.
