Hi, I finally solved this issue on my macbook pro.
Current running version is OS X 10.8.2
I have had this WiFi pbroblem for over 4 months and tried every possible solution/advice including BDAqua.
What solved it was 802.11 Band Friquency:
Steps:
1. Open a web browser, enter IP address for your router/modem and open the web page. IP address is different for different modem brands. Check with your provider/manufacturer. (For Motorola Surfboard the IP address is 198.168.0.1) FYI: My Internet provider is Time Warner cable
2. Log into your modem/router. You need User/Password. (Ask your provider or Google it) For Motorola Surfboard default login: User Name = admin, Password = motorola
3. On top of the page, from the options choose and click Wireless
4. In Wireless, from the options on the left click Basic. The page will change and display options. Please see the picture below.
5. Wireless interface will be there by default. This is a name of your WiFi name and BSSID. I just erased mine. FYI
6. Change 802.11 Band from 2.4 Ghz to 5 Ghz
7. Set the rest of the options as on the picture.
8. Click Apply on the bottom of your page.
9. Click Logout on the top of your page.
9. Restart your modem/router by unplugging all wires, waiting for 20 seconds, and then plugging everything back.
10. Restart your computer while the modem is restarting
11. Go to network setting on your computer, Renew DHCP Lease, click ok, click apply.
On my macbook pro: System Preferences - Network - WiFi - Advanced - TCP/IP settings are:
- Configure IPv4: Using DHCP (Works with manual settings as well)
- IPv4 Address: IP address of your WiFi
- Subnet Mask: 255.255.255.0
- Router: 192.168.0.1
- Configure IPv6: Automatically
- My DNS is set as 8.8.8.8
That is it.
WiFi is stable and running over a week now.
