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?

    In Network Preferences:

     

    Set location to Automatic and Configure to DHCP

     

    Turn off IPv6 in Advanced

     

    Sometimes temporarily turning on Broadcast Name at the router can cure problems but this is usually if Macs cannot find the router at all.

     

    Check that you are connecting to your router and not another one.

    Is there evidence that the 2 bars is your router and not another one?

    Your router may need either a firmware update, or to be replaced.  Not all routers are compatible with Apple's Energy Saver.

    Can you explain this? What interaction is necessary upon waking from sleep?
