Care to share what they all were other than what you already stated?

Please detail ALL you have done so far in the way of troubleshooting?   Need this info to avoid the been there done that scenarios.

Have you read for possible solutions over in the "More Like This" thread over here?----------------------->

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.

Step 1

Back up all data.

Triple-click the line below on this page to select it:

/Library/Preferences/SystemConfiguration

Right-click or control-click the highlighted line and select

Services ▹ Reveal

from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.

*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select

Go ▹ Go to Folder...

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

Step 2

Reset the System Management Controller

What were the results of network diagnostics including the color of the status buttons?

You may have already tried some of the following.....

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.
