Wifi on iMac6,1
Recently I changed my cable connection to a wifi connection to my router. Now, there seems to be a problem when my iMac wakes up from the sleep modus.
The wifi connection is very slow or not working at all. By switching on and off Airport several times I can force the wifi to work again.
My router seems to be OK because i can connect with my iPhone without problems.
A software update doesn't fix the problem.
How can I resolve that problem?
