At work when I am away from my desk I activate my screensaver on my macbook. When I return to my desk and log back into my macbook, I have to reconnect to the wifi signal. Why is my macbook diconnecting from wifi when I activiate my screensaver? This is a new problem and has not always done this.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.3)
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
