Ask Computer Networking Questions and Get Answers ASAP
Please go to the Apple logo at the upper left of your computer screen to About This Mac and give me this information:
Is the Airport cone at the top of your screen staying filled or does it go to gray bars?
OK that is your WiFi signal in the house....
1.) Open System Preferences2.) Click on Network3.) Near the top-centre is a drop down menu that says "location". Click on this and choose "Edit Locations..."4.) Click on "+" button to create (add) a new Location.5.) You might notice the arrangement of network services (the icons in the left column) changes. These services can be re-arranged so that your macbook tried out the one at the top first. If you want to use WIFI mainly, click on the button with a gear and choose "Set Service Order" Then drag your Airport Service to the top of the list. This'll tell your macbook to use your airport card to connect to the internet first before using the others. If your airport fails though, it'll use the next one on the list. One crummy thing about this though, is that you can be connected to the wifi network but your TCP/IP settings are messed up and it won't give you internet. In this case it may/ may not use the other services to connect to the internet.6.) Anyways, with this new location, you should be able to try again "from scratch". See if it works now :)
Ok but I wanted you to create a new one call it Home or something the point is to make a new set of preferences
