Does not automatically connect to wireless network anymore

Mac Book does not automatically connect to know networks any longer.

Hi sashton,
When troubleshooting Wi-Fi connectivity issues, I find the following resource has the most relevant information:
Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6

Furthermore, you may want to avoid giving your network a common name. While the following article (and excerpt) refer to iOS devices, the same applies for your Mac:
Avoid giving your wireless network a common name (SSID)
http://support.apple.com/kb/HT4450
If you were to give your wireless network a common name (SSID), users of your network who use iOS devices [sic] and are away from your network would run the risk of joining a different network with the same name. Having joined the unexpected network, they would be exposed to potential data theft.
Because of this security issue, Apple maintains a list of common or ambiguous SSIDs, including the default SSID for many commercially available access points, as well as the SSIDs "wireless" and "default". If your network's name is on the list, any iOS device [sic] that joins the network stores the access point's BSSID and associates it with the network's SSID. Subsequently, it will only auto-join the network if the access point's BSSID matches the information the device has stored. This avoids joining a different network with the same name.
Therefore, you may want to refer to the following article when configuring your Wi-Fi router:

  • Does not automatically connect to my network anymore

    When I first got this Laptop a few weeks ago it would connect to my wireless network immediately. However, I downloaded a windows network program by mistake last week and, even though I deleted that program, I now have to get into Network Magic , go to view available networks and wait for a few seconds for my linksys network to show up. Then it connects with no problem.
    What can I do to get it back to the way it was?

    Hi dvenneman,
    Make sure that at least another computer in your Network has Network Magic installed.
    Uninstall Network Magic from the laptop and reboot. the computer. For the XP Computers.
    Use Explore and remove the following folder and its sub-folders:
    \Documents and Settings\All Users\Application Data\Pure Networks
    \Program Files\Pure Networks
    Still using Explore manually clean out your \Temp Folders. Run Disk Cleanup.
    Run a Windows Registry Cleanup program to clean your Registry.
    A good one, is TuneUp Utilities 2010 at http://www.tune-up.com/products/tuneup-utilities/ 
    Reboot.
    Make sure that you are connected to the Router.
    Reinstall Network Magic.
    Use another computer to Activate this copy of Network Magic.
    Report back.

  • PC will not automatically connect to wireless network on startup...

    Hi all - I have a WRTG54 wirless router with the latest firmware.  Windows XP Home SP2.  I have a mixed network with two wired PCs and one wireless.  The wireless PC will not automatically connect to the network. To connect to the network i have to go to the wireless network properties box and check "let windows automatically configure network"  Once I do this the wirelss PC connects with no problem.  Unfortunatley, whenever i turn the PC off and turn it back on the "let windows automatically configure network" is unchecked and i have to go through the process of checking it again.  I uninstalled the wireless adapter and reinstalled the drivers only and then ran the windows wireless setup wizard but the problem persists.  Any help on this would be much appreciated.!!!! Thanks!!

    First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
    Do not let "Windows automatically configure your network".  Instead do the following:
    Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use.  Delete your current network (this will remove any old settings).  Reboot computer.  Return to "Preferred Networks" and re-enter your current network info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".  Reboot computer.  It should connect automatically.  If you still have trouble, in the computer, temporarily disable your software firewall, including Windows Firewall, and see if that helps. 
    Some users have reported improved wireless connections by switching to WPA  ( = WPA with TKIP)  encryption.

  • T60 does not automatically connect to wireless profile at bootup any more

    Probably my rose-colored-glasses mistake again. 
    I let the ThinkVantage system updater install most of the latest updates last night including the
    wireless adapter software.  Now, when I boot up, my PC no longer automatically connects to
    my wireless profile.  The radio is on and it is obvious it knows the network is there because it
    is highlighted in the Access Connections menu with a Connect option.
    It connects just fine when click Connect. 
    It will still automatically switch between ethernet and wireless when I plug and unplug the
    ethernet cable even if I have specifically disconnected from the wireless connection before
    plugging in the ethernet cable.  It also automatically connects when I log off Windows and log back on.
    Is there a setting some place that controls whether it should automatically connect to a
    wireless profile at bootup?
    I love the brain-dead online FAQ about this exact problem.
    It says to click the Connect button if it happens.
    Well, duh!  What do I do to make it automatically connect like it used to?
    I tried unchecking the "allow computer to turn off the radio" setting as other suggested.
    But, my problem is not the radio being off.
    Thanks

  • My macbook air does not automatically connect to my network when i go on safari

    I just replaced the hard drive in my macbook air, now when I try to log on to safari, it says I am not connected to my wireless network and I have to go to system preferences and pick my network and log on. Even though I lock the changes after I log off and come back I have to do it all over again. Any suggestions?

  • Apple TV does not re-connect to wireless network after standby

    When I 'turn on' my ATV after it has been in standby mode it will not re connect to my wlan. I have to do a restart of the ATV box before it will find the network again. Needless to say, this is a complete pain....anyone else suffer from this or know a fix ?
    Thanks,

    I removed the file "com.apple.networkConfig.plist" from the Library\Preferences folder and restarted. Now my network is found after restarts and wake from sleep.

  • IPad (3rd generation) does not automatically connect to wi-fi.

    iPad (3rd generation) does not automatically connect to wi-fi.  It is fully updated to 5.1.1 but you have to manually connect after turning off and back on.  I also have an iPad 2 with the same OS but it automatically connects.  The wi-fi has no security.

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

  • Wicd does not automatically connect to eth0

    Wicd works fine using my wireless network. It does not automatically connect to eth0 when I plug in a cable, but I can connect to it by pressing connect manually.
    I already have ethtool installed (do I need to run ethtool as a daemon???)

    stabele wrote:I have two maybe naive question:
    1)are you connected to wireless network before you plug in ethernet cable? If yes, than wicd does not automatically switch to wired network. Maybe you can get it done by custom scripts wicd support for each connection, but I never used this thing in wicd.
    2) do you have disabled in rc.cong interfaces you want wicd to manage INTERFACES=(!eth0 !wlan0) ?
    Thanks for your answers, 1) no I'm not connected to wireless, and 2) eth0 is disabled.
    I found out it works fine if I connect eth0 manually and then I can remove and plugin the cable all I want and it automatically connects. This is because dhcpcd is already running for eth0 so maybe I should run dhcpcd eth0 in a boot script (although I think wicd should do this).

  • Yoga 13 does not automatically connect to Wifi at times

    My yoga 13 does not automatically connect to WIFI at times thought it has been saved to automatically connect. It will connect after I click on the WIFI icon in the desktop and then it sees the WIFI network and automatically connects to it. Though it is not a big deal it is minor inconvenience that I have to click that icon at times when internet doesn't work. This shouldn't be the case for a laptop that retails over 1000 bucks. Any suggestions?

    This happens to me too. I haven't found a solution yet either.

  • Windows 8.1/IE 11 Does Not Automatically Connect to the Internet

    Windows 8.1/IE 11 Does Not Automatically Connect to the Internet
    I can't find the dial and redial options anywhere.
    I' m connecting through PPPOE but only manual.
    I know that in windows 7/8 a program like IE9 or IE10 could connect to the internet, but now it just says that I am not connected to the internet.
    How to connect automacally to the internet and how to let IE to connect automatically to the internet, and why I don't have the options for dialing and redialing like in Windows 8?
    Thank You

    Hi,
    Sorry for my dilatory reply, what does your mean that IE dialing to connect to internet?  Did your system can connect to Internet? or just IE 11 couldn't connect to internet. you can
    check your IE poxy setting in Connections of Internet options.
    If you encountered any IE problem, you can try to reset IE for test to resolve this problem.
    If you need further assistance on this particular issue or any other Windows related issue, let us know and we will be glad to assist you.

  • We bought a time capsule then the wifi has a problem since it does not identify the existing wireless network and it says that its need to have an update firmware. The existing firmware is 7.3.1, does it have an newest update firmware existing now?

    We bought a time capsule, 1TB, then the wifi has a problem since it does not identify the existing wireless network and it says that its need to have an update firmware. The existing firmware is 7.3.1, does it have an newest update firmware existing now? Does APPLE do not provide latest firmware for this item?

    How old is that Time Capsule?  The fact that it still have firmware 7.3.1 suggests that it's not the latest model.  The latest firmware available for my two-year-old model is version 7.5.2.  Apple does provide firmware updates.  You just have to let the Time Capsule download and install them.  Use AirPort Utility to do that.
    Regarding your Wi-Fi problem, please explain what you mean by "it does not identify the existing wireless network".
    By the way, you've been misled by poor field labeling on this forum into typing a large part of your message into the field intended for the subject.  In the future just type a short summary of your post into that field and type the whole message into the field below that.

  • Does not automatically connect to recently used WIFI networks

    Recently purchased 13" Macbook Air, with Lion installed. All's well, except upon start-up or waking up from sleep mode, it does not automatically re-connect to the WIFI network it was just connected to. Instead, I'd have to manually find the network to select it. (Incidentally, some of my friends who also use Macbook Air and Macbook Pros have also experienced this periodically.)
    Another strange thing, is that there is this one particular WIFI network at work, that I've successfully connected to before, upon return the next time, all of a sudden, the network isn't even visible anymore. My OS5 iPhone sees it fine, and never has a problem, but repeatedly this happens. Other people at work who also use Macbook Pro and Macbook Air also encounter the same problem. People who are using PCs don't have the same experience.
    Is there a setting somewhere? I have "Remember networks this computer has joined" checked, and I see the particular network listed as ones I've joined.
    Any light that can be shed on this would be greatly appreciated. It's very frustrating, especially Airs don't have a built-in ethernet port. I hate using the adapter, it steals one of my USB slots.
    Thank you in advance!
