It disconnecting every time I turn it on my Mac or when it wake up after sleep mode. It was not disturbing at the begening but now it starting to gets on my nerves...
Hope you can help me.

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
5. In some cases, the problem has been resolved by repairing permissions on the startup volume.
6. Reinstall OS X.

To fix the WIFI problem, please proceed in these steps until is fixed.
Note: In steps 3 and 4 you are dealing with hardware problems. An alternative to them is to bring the computer to the Apple Store. These steps can ruin your laptops if you are not good with working with circuits boards. A new airport card is less than the $100 that Apple would ask you but if you break your laptop you have a more than $1,000 loss. Attempt these steps at your own risk.
