Q: MacBook Pro Doesn't Always Connect to WI-FI Router at Start-Up

I have an internittant problem with my MacBook Pro (8,3 - 2011/Intel Core i7). It's configured with original Airport Extreme card. For the most part, the wireless system runs without a problem. I've always been able to connect to wireless networks at home or when traveling... encrypted or not... no matter. I'm running Lion 10.7.5 and stay current with all software and firmware updates.

 

A few months ago, I started having an odd problem. At start-up, instead of the wireless connect icon on the top right-hand side of the menu bar showing the full four wave-shaped, black bars as static and solid, indicating the computer is connected to the wireless network, the icon would instead appear to be searching for the network indefinitely -- sometimes showing the telltale exclamation point in its center indicating no connection.

 

I couldn't understand this given that I'd been using this router without any problem for months. The MBP had logged on to our WPA-encrypted network without any problem.

 

When I phoned AppleCare, the tech insisted that I was getting interference from other wireless networks in the area and that I should change the channel on the router to a channel well separated from the channels of the other networks nearby. I tried this, and it seemed to help at times, but at other times, not.

 

As part of this process, the AppleTech asked me to generate a system report from the About This Mac menu, and then click on the Network/Wi-Fi tab to identify the wireless networks in my immediate area and their channels.

 

Curiously, when this problem occurs again lately, and the MBP cannot connect to our wireless network, I've been generating a system report to see where the interference may be coming from. When I click the Network/Wi-Fi tab, I see our network -- let's call it "Fred" listed not just once... but twice. The real Fred network that actually works is listed under "Other Local Wi-Fi Networks". The second Fred network, to which my MBP is trying to connect, is listed under "Current Network Information".

 

The strange thing is that this second, unusuable network or ghost network (I'm not really sure what it is) has a BSSID of 00:00:00:00:00:00.

 

When this problem started happening months ago, the only way I knew to solve the problem was to keep restarting the computer until I finally booted into the right network (after logging into my usual user profile).

 

What I finally figured out (Doh!) is that when this problem does occur, I can simply click on the wireless icon, click Join Other Network, then Show Networks, see a selection window with the real Fred network, click on it and in a moment I'm connected to the real Fred wireless network and ready to go. It's an easy, simple workaround, but I'm concerned about why I'm seeing this "ghost" network of Fred with the BSSID of 00:00:00:00:00:00. Is this some indication of hacking or foul play or someone trying to tap into our network or computers? -- either locally or via the web?

 

Curiously, I notice this only occurs when I use my usual non-admin ID, which is the one I use to surf the net and send/receive emails for all the obvious reasons -- specifically, the extra layer of security. But when I occasionally log-on with my admin account, I never have this problem. Is it possible my non-admin account wireless settings have been corrupted or compromised in some way?

 

How do I solve this problem?

MacBook Pro, Mac OS X (10.7.5)

    Try the basics first (some of which you have already tried):

     

    Change your router channel number.  Most times this works & is all you have to do.

     

    Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

     

    System Preferences>Network

    Click the Assist Me button.

    In the next window that pops up, click the Diagnostic button & do the necessary.

    Have a local Mac/PC tech come out and secure your network, either update your routers firmware or get you a new one.

     

     

    WPA has been cracked, only WPA2(AES) is secure with a good long crazy random character password consisting of 20 or more characters to prevent brute force cracking.

     

    This would make a good password example for the router's account: RGE´‰ˇRRT$#%Ct5s906suÎmd84tu

     

    Then remote Admin, hidden networking, MAC address filtering and PING need to be turned off, however Apple's routers don't allow PING to be turned off, so your susceptible to PING floods and botnet attacks on your password/router, however if the password is strong enough and the firmware updated then it should hold.

     

    No computer on your network should contain the routers Admin password, especially not stored in Keychain. This one is stored on paper in a safe location until needed. Also a Admin router access account on the router should not be used for day to day use, only a Guest Access account and different password used instead, this is so the router's admin password is protected from malware changing/infecting the router.

     

    You might be getting interference and/or the router is dying/old and needs replacement with a newer, more powerful one as it might be getting drowned out by a neighbor. Newer routers are better protected against interference than older ones.

     

    Using WPA Encrypted tells me that the router is old and the security hasn't been updated to WPA2(AES) standards.

    Thanks for the input... some additional info.

     

    I'm currently living and working abroad and receive internet service through the local cable company. As such one has no choice but to utilize their modom and router which live in the same box made by Thomson for the cable company. Their technology is some years behind the first-world and so there are inherent limitations as to what I can alter and modify.

     

    More to the point though... can anyone explain the origins of the ghost nework with the BSSID of 00:00:00:00:00:00 mentioned in the OP?

     

    That was and is my primary reason for posting this question.

     

    Thanks!
