    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 your router and your broadband device, if they're separate. Any change?
    • Run Software Update and install all available updates for OS X or your computer's firmware. Any change?
    • If possible, connect to your 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?
    • Boot in safe mode and test. Any difference?
    • Boot into 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?

    The wifi signal shows the strength of your signal and not the speed of your internet. Try connecting any other device (phone/laptop) and check for internet speed. if it is slow there too then Linc Davis has shown you the way to diagnose it.

    I've the same problem with a mid-2013 13" MacBook Air model A1466 purchased in November and face the same problem. The laptop was bought to substitute a 2008 Macbook White that receive a low signal in a bedroom to the opposite side of the house to where the router is, but still worked pretty fine.


    The Macbook Air always shows a full wi-fi signal (all 3 lines full), but works very poorly in the same bedroom.


    Shouldn't it at least show that the signal is weak? Shouldn't a much newer computer have a better wi-fi reception?


    Any fix on this? Thx!

    Downloaded the MacBook Air (Mid 2013) Software Update 1.0 that seemed to fix wi-fi problems with the model, but it's not compatible with Mavericks (apparently runs only up to Mountain Lion). Does anybody know anything about this?
