Why my MBA don't reconnect to WiFi after sleep?

So whenever I put my Mac to sleep (the lid), it refuses to connect to my WiFi at home.

I have try the diagnostic assistant, who tells me that I need to reset my router. I know that this is not the case since I'm logged in on other devices.

I did a little research and am looking for a solution that doesn't require me erase all previous WiFi access points.

Anyone know anything?

Please test after taking each of the steps that you have not already tried it. Stop when the problem is resolved. Back up all data before making any changes.

1. If possible, test at another network, such as a public access point or hotspot created by a mobile phone. Some Wi - Fi routers are not fully compatible with Apple devices. More specifically, the security mode for the network, as shown in the network preferences window, should be 2 personal WPA or WPA 2 Enterprise. If the router doesn't support either of these modes, it should be replaced with another.

2. make sure that the network is on the list of favorites by following these instructions. It is important to read the article, as it is the starting point for further efforts to solve the problem. If you skip any step, the problem cannot be resolved. Make sure that the box marked

7. run the Keychain Access application. Find and remove all the network password AirPort elements that refer to the network. Make a note of the password first.

8 turn off the Bluetoothand the test.

9. reset the system management controller.

If necessary, click the lock icon in the lower left corner to unlock the settings. When prompted, enter your administrator login password.

    My iphone 5 iOs 9.2 my photos off wifi have tend to be blurry how can I stop this to keep download when I reconnect to wifi?

    Hello Mikecici,

    Thank you for using communities of Apple Support.

    I understand that your photos will look blurry, whenever your iPhone is not connected to the Wi - Fi.  This indicates that you probably iCloud library enabled with the option of storage optimize.  If you have cellular data disabled for Photos, which would prevent photos life-size uploaded without a Wi - Fi.  To learn more about iCloud photo library, please take a look at the information in the link below.

    Can I use iCloud photo library to save space on my device?

    iCloud photo library automatically keeps all of your photos and videos in the original version, in high resolution. Follow these steps to choose how you store your photos and videos on your device:

    • On your iPhone, iPad or iPod touch, tap Settings > iCloud > pictures or settings > Photos & camera, then select a storage parameter.
    • On your Mac, click on Photos > Preferences > iCloud, and select a storage parameter.

    If you turn on [device] Optimize storage, iCloud photo library manages automatically the size of your library on your device, you can make the most of your device storage and access photos more than ever. All of your original photos, full resolution and the videos are stored in iCloud while unit size versions are stored on your device. You can download original photos and videos over Wi - Fi or cell phone when you need it.

    If you turn on download original, iCloud photo library will keep your original, full resolution photos and videos on iCloud and on your device. Download the originals is the default setting for iOS devices with 5 GB free storage plan and all Mac devices.

    You need an Internet connection to access a photo original or video that is stored only in iCloud.
