Wi-Fi issue after update to OS X Mavericks

In this week, I find my iMac always show "No Internet Connect" on the WiFi signal bar and it can't connect to the internet after the iMac wakeup from sleep mode.


However, the signal is full and already login my wifi when it show the issue. I need to re-open the wifi to solve the problem.


Any one have this problem?

iMac (21.5-inch, Late 2012), OS X Mavericks (10.9)

This sometimes occurs when your computer wakes and it shows an error. This because when it does wake and your desktop shows all the icons and you start to use the compuer the error message comes. The reason is you are not giving the machine time to come fully awake. mine does it also. give your machine a little time and it will automaticlly re activate the Airport back to normal.

I am trying other solutions today.

It can not change to another wifi network without switch off the wifi.


That's mean I have switch off and re-open the wifi signal every time when it show like this capture.


I waiting for more than 5 mins and it will search another wifi network automatically but it still "No internet connect".


My MacBook Pro is no any WiFi issues.
