Hi Lyn and Kristeen, I'm not sure I have a solution for you if you only connect to one wifi network, but I can describe a generally recommended fix. Are you running Lion? The location profile is the name assigned to your network setup, and is probably set to "Automatic". If you navigate to the Apple menu on your menu bar (either VO-M or Control-F2 to move to the "Apple Menu"), then arrow down and press "L", you'll find the "Location" menu entry. Pressing your right arrow key will move you to the submenu, and you'll probably find your first entry is "Automatic" and is selected. If you arrow down the submenu, you'll find entries for any other location profiles you may have created, and if your press Command+Down arrow, you'll move to the end of the Location submenu, which should be the option to open "Network Preferences…".
You can create different location profiles for different network setups -- for example, I have a separate one for my Father's Wi-Fi network. Or I have another profile named "Office" for the fixed IP ethernet connection at work. The usual fixes for the sorts of problems you are seeing is to create a new location profile for your network, in case the initial one has somehow been corrupted, and try using that instead to see whether the problem goes away. If you are losing the connection on the same network that you usually use, but only after your Mac goes to sleep, you can also try renewing the DHCP lease. Here's a link to a recent OS X Daily article that outlines the steps to take. They include applying all the latest software updates for Lion, and first resetting your router (just power cycle it). Then the suggestion is to try creating a new network location and renewing your DHCP lease. You can follow the instructions of the article to launch "System Preferences" from the Apple menu and select "Network", but I find it faster to simply navigate to the "Network Preferences…" option at the end of the "Location" submenu, since this will take you directly to the window you need without having to navigate more menus. The article is titled "Still Having Lion Wi-Fi Problems? This Solution Works": http://osxdaily.com/2011/11/06/lion-wi-fi-problems-solution-mac/ Their suggestion is to create a new location profile for your network by clicking the icon to add a new network connection. My suggested version of how to do this: 1. Press VO-M or Control-F2 to move to the Apple Menu 2. Arrow down and press "L" to move to the Location menu 3. Right arrow to the "Location" submenu (you should hear VoiceOver announce the first item, probably as "Automatic " with a preceding check mark). 4. Command+Down arrow or arrow down to "Network Preferences…" at the end of the Location submenu (you will pass the names of other location profiles if you have created any); then press either VO-Space or Return to open the "Network Preferences" menu of "System Preferences" 5. On the "Network" pane, first unlock the lock button with your Admin password by using item chooser menu to go to the "Click the lock to make changes" button. Press VO-I for item chooser menu, then type "b u t", for a list of buttons, then type "l o c k" to locate the "Click to lock to make changes" button, and VO-Space twice (once to move to the button and a second time to click the button). 6. In the Authentication dialog window that is brought up, you'll be in the password field. Type in your Admin password and press Return to unlock the button. 7. Use item chooser menu (VO-I) again and type "a d d" to locate and move to the "Add Service" button. (Again, press VO-Space twice -- once to move to the button from the item chooser menu, and a second time to press the button). 8. In the dialog window you'll be prompted to select the interface and enter a name for the new service. Set the pop up menu to "Airport" (which is probably the default), and type a name of your choice in the text box for the service name -- just something that is different from your existing location service name of "Automatic"). Then navigate to the "Create" button and press it (VO-Space). 9. On the Network pane for the newly created service (announced in the pop up button following "Location" at the start of the pane), navigate to the "Advance…" button, and press it with VO-Space 10. Navigate with VO-Right arrow to the "DNS" tab and select it with VO-Space. 11. On the "DNS" tab navigate with VO-RIght arrow past the IP Address (if you continue to navigate, there will be a series of numbers for the IP Address, Subnet mask and router. They will all be groups of four numbers separated by periods.) Navigate to the button for "Renew DHCP Lease" and press it with VO-Space. 12. Navigate back (VO-Left arrow) to make sure the fields for IP Address, Subnet mask, and Router contain numbers, since pressing the button to renew the DHCP lease will cause these fields to update. 13. Once you have checked that these fields are populate, navigate to the "OK" button at the end of the pane (either with VO-Right arrow or by pressing VO-Fn-RIght Arrow to move to the end of the window) and press it with VO-Space. 14. You might want to navigate to the "Click the lock to prevent further changes" button and lock it again (with VO-Space) before closing the Network window with Command-W. Read through the article at the linked URL, perform the updates, and see whether this helps. You'll now have two location profiles in your Location submenu under the Apple menu. See whether the new location profile behaves better. If it works, you can keep it and delete the old one. You will have to enter the password when you set up this location profile. Write back and let us know whether that helps. HTH.
