iPod touch iPod touch wifi died after 10.5.7 update?

[samac92]

This morning my iPod touch wifi stopped working, the network name is there in the list, but when I tap it it says "unable to connect"
I've tried everything from restoring my iPod to changing the router settings, still nothing.
The only thing i can think of doing is updating to 10.5.7 on my MacBook yesterday and then syncing my iPod, but I can't see how these are linked, must be a coincidence.

Just very annoying as my warranty ran out only 6 days ago!!

EDIT: ok false alarm, I've found out it's because I had mac address filtering turned on on my router, but I'm not sure why my iPod mac address would have changed?
anyway works fine now

Are you sharing your macbook's internet through airport? I noticed that my internet sharing broke after updating to 10.5.7. In my case I was sharing via the ethernet port. Anyways, I simply turned Internet sharing off and then on again, and all was fine.
