Care to share which OS you are using?
Call your ISP to determine if the problem is on their end.
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.
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
Research Knowledge Base for network problems that pertain to the OS that is currently installed on your computer. See these basic networking KB Articles: http://support.apple.com/kb/HT1401 AirPort troubleshooting guide

Also, run the Airport Utility app which is located inside the Utilities folder.
If using Apple's Airport, please re-post over in one of the AirPort Forums.
On your Mac, go to Apple Menu > System Preferences >Network > Airport and click on Locations and Edit Locations, create a new one and use that.
Head to Advanced TCP/IP and delete all the previous connections.
Check your date and time are also correct and currently updated.
Turn off your router and modem.
Shutdown all other devices and the Mac or take the iPhones way out of range.
Boot the router and modem and when it's blinking up good, boot up the Mac and log on, save into Keychain.
Bring the iPhones etc., into wifi range and reboot.
What I suspect happened is one of the other devices had a local IP conflict with the router, so thus by forcing everything to connect to the router again fresh, the router assigns a new local IP to each machine accordingly.
The new location on the Mac is to resolve any issues there that were misconfigured.
Im so sorry. As I've said earlier, Im no techy. Please give me instructions step by step as I completely have no idea what to do or how to do things with computer(technology).

Click the little plus sign to create a new location and select it.
Click on Wifi and if you see all the previous connections the machine made, just use the minus sign to delete them all and Apply if it's there.
Then click Show All and head to Date and Time and make sure it's current and updated to your location, then quit and shutdown the computer.
