Q: Wifi connection constantly dropping

I am currently running Lion OS 10.7.5, and connect to the internet via Wifi. My issue is that my Wifi connection drops constantly. Currently my "fix" (very short term) is to click on the wifi icon in the menu bar and turn wifi on, off, and on again. The connection resumes for a short period of time, but always drops again within a few minutes. My modem is an AT&T 2Wire Modem. Any help with this issue would be greatly appreciated. From my small bit of research on the subjet, it seems to be a fairly common problem.

iMac, Mac OS X (10.7.5)

    Hi, this has worked for a few...

     

    Make a New Location, Using network locations in Mac OS X ...

     

    http://support.apple.com/kb/HT2712

     

    10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    10.4 instructions...

     

    Is that Interface dragged to the top of Network>Show:>Network Port Configurations.

    If using Wifi/Airport...

     

    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

    Thanks very much for this fix BDAqua. I've done as you've suggested and so far so good. I will update this post if things revert to losing connection again.

    Just wanted to follow up after having tested this fix. This seems to have pretty much taken care of this issue for me. At times, I can say that a page will "hang" before eventually loading, but I no longer get the gray page stating "you are no longer connected to the internet." Thanks very much for your help!

    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.

     

    WiFi Settings for Surfboard.png

    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.
