Since upgrading to Tiger I have experienced a slow down of my Airport Extreme.
First I thought it was a signal problem but had the DSL provider check the signal and they indicated it was strong and fine 800kb incoming. The signal was only 50kb exiting the Airport Extreme.
The DSL provider felt maybe the Airport was defective.
I am running the lastest Airport firmware. The Airport wireless card signal is full.
So my DSL service is now slower than 56k modem speeds.
Any help is much appreciated.
