Why does my home network not show up sometimes in my network listings?
Your 10.9.5 and your Router are having problem of identity.

Your 10.9.5 can not find the correct name, or your router is not broadcasting it correctly. 

So try changing the name of your Network, and make sure it is moved to the Top of the Network list and choose different Chanel. 

Also you could tell the router that your MAC address belongs to trusted ones.

I would not panic but on they web site they skipped 10.9.5 (Mavericks) and call it Yosemite ?

Probably just a stupid typo :)


  Mac OS X 10.7 Lion Mac OS X 10.8 Mountain Lion Mac OS X 10.9 Yosemite
