Hi Roger,

One thing you could check. Look in HD > System > Library > Extensions and see if there is a file AppleAirPort2.kext.
 If there is drag it to the trash and empty the trash.

This file is left over from Mac OSX10.4.x and interferes with wireless connections after Mac OS X 10.5 is installed.

Cheers,
Ronni

Hi Guys

I have a MacBook Pro and since installing Leopard wireless networking has
been awful!!  Tiger was fine on the same machine?

What happens: when I get a connection usually after a long shut down its fine until I let it sleep it will then get a self assigned IP address and there is nothing you can do to get the DHCP address back and I am still
connected to my router in the airport menu.

I have booted off an external tiger system and its fine.

Leopard is patched with all updates.

Hope everyone has had a great Christmas

Regards

Roger
