Q: WiFi problem

Hello

 

I have had this problem recently with my 2011 MacBookPro. My Internet connection is really slow and randomly stops working without any warnings. This problems extends to many routers and places so this is definitely related to the computer. It a constant problem for my only getting access to the net at random times during the day.

 

It is really hard to describe but the way I see is the connection stops working and the computer and I when try recconnect the system just tells my the network could not be joined, sometimes restarting works.

 

 

Does someone here know what´s wrong?

 

Kind Regards

MacBook Pro (13-inch Early 2011), OS X Yosemite (10.10.3)

    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.  Report back the results.

    Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.

    • Restart the router and the broadband device, if they're separate. Any change?
    • Are you connected to Ethernet as well as Wi-Fi? If so, disconnect the Ethernet cable or adapter and test.
    • If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
    • Are any other devices on the network, and if so, are they the same?
    • If you can connect to more than one network, are they all the same?
    • Are all network applications affected, or only some? If only some, which ones?
    • Is networking always the same, or is the problem intermittent?
    • Disconnect all other devices from the network. Any change?
    • If you're running a MacBook with the lid closed, open the lid. Any difference?
    • Start up in safe mode and test. Any difference?
    • Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
    • If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?
