My 13in Macbook Pro can't see a wireless network but my friends Macbook Pro can

Me and my friend both have identical 13 in Macbook Pro's except he has 250 gb and I have 350gb. Everything else is the same even the wireless card. The problem is, he can see and connect to a unsecured wireless network but i can't. Why is this ?
Our computers can see the same networks on the list but my Macbook does not see one network, the unsecured network !!!

I never said there wasn't an issue, just that blame could not be assigned based on what we know now and that there are many more people not having problems with Leopard and WiFi than those that are.
In my circle of associates I know of literally hundreds of Mac owners, of which approximately three are having WiFi issues.
I know how frustrating it is to be one of those afflicted - my stories of constant WiFi drops for the first six months I owned my MBP have been recounted in several threads.
But it's just as frustrating to read how Leopard is just plain broken when in fact I've not seen a single WiFi drop in Tiger or Leopard since February 2007.
This is also why I've continually urged people experiencing the problem to open an AppleCare case - it's only then that Apple Engineering can find the commonalities in cases where WiFi is failing and either fix their driver or notify the router manufacturer of their bug.
Are there bugs with AirPort in Leopard? Of course, and I even know of one that affects me on occasion that's known, and that's a failure to reassociate with a known network when waking from sleep. The workaround is simple - toggle AirPort off and back on - but it's a known issue nevertheless.
But each of these threads addresses an individual problem, and among the numbers of people experiencing difficulties, few report that their Mac sees no wireless networks, and that's what the advice I've given in this thread is geared towards.

  • Can't see any wireless network on my g5 dp2.5 can anyone help?

    hello - i have just bought a 2005 model dp2.5 g5, and an airport extreme card. I have a wireless network at home which my other macs are all seeing fine, but this new computer won't see any network at all. i tested the extreme card by putting it in my laptop and it works fine. have tried to log on manually but again the computer doesn't see any network. the airport logo is there on the top menu bar but with no signal.
    any ideas?
    Tony

    Very similar topic. I have a g5, but I have a windows desktop, windows laptop, and xbox360. I have an airport extreme card with the antenna in place. The two windows machines have their wireless network cards and antenna.....the xbox has it's wireless adapter. When I start up the machines, the three microsoft machines connect just fine, the G5 won't connect. I can run an ethernet cable to the Linksys G router, and sometimes that kicks in the airport card. But who wants to do that every day.
    I can share files between the two windows machines, but not to the powermac. not sure about the xbox360.....the wireless adapter is an xmas present. But connected via ethernet cable, the xbox won't work with anything.
    Help please.
    Harry.
    I just bought a new router with the notebook which I got a couple of weeks ago. The old router was a B and the new one a G, but that is moot. Everything is backwards compatible....and none of the machines support X.

  • I can see my wireless network,but my ipod4 will not let me connect to the network?

    I can see my wireless network, but my ipod4 will not let me connect to it. When I try it tells me that it is unable to join. I can access the network on my laptop fine. I am also having trouble with connecting my ps3. It has the exact same problem. Can anyone help me?

    The ps3 problem tends to indicate a router problem.  Have you powered off and then back on your router?
    For the iPod try:
    - a reset:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Reset Network settings: Settings?|>General>Reset>Reset Network Settings

  • My airport express can't see my wireless network

    I am bringing up a new AE in my wireless network. I have set all the internet and wireless configurations. I am trying to add it as a client, initially connected to my router via ethernet. After tweaking several settings I am now down to what seems like a critical problem: Airport Utility tells me that my AE cannot see the wireless network. This is a bit amusing since I unplugged the ethernet and am communicating with it solely via wireless.
    My config: static IP addr reserved in my router, WPA2 encryption, ethernet clients allowed, using my router as the default DNS server. Running the latest firmware and Airport utility according to Apple Software Update this afternoon. Router is an SMC Barricade N with latest firmware.
    Any and all advice greatly appreciated.
    Roger

    Thanks for the ideas, but alas those are not the cause.
    I am broadcasting SSID and I am running mixed b/g/n mode. FYI Airport Utility finds my network OK, as do the many other pieces of networking equipment in my house (4 computers, a NAS, an SMC wireless client, etc etc etc.) Even my son's Touch, after going through very similar games with Apple, solved by an OS upgrade a couple months later...but I digress.
    Spent an hour with the Apple expert on the phone verifying everything was right on the AX and then took it to my local apple store where they were able to connect it to their G router as a client - thus eliminating wrong AX config and broken HW as a cause.
    Here is what I know: it has to be able to see my router because when I bring it up my router sees it and issues it an IP address. I might reserve the IP and then set it to always use that. That is one of the things we did to get the Touch working initially.
    Again, thanks and any new ideas appreciated.

  • Our iPhones can't find our wireless network, but our MBPs can?

    Using AirPort Express. Me and my friend's MBP can connect to the wireless just fine, and we can see the wireless network name on our MBPs.
    But when we use our iPhones, our wireless network is nowhere to be found, tried resetting to factory settings and restarting modem etc. Same problem happens to other devices i.e. other laptops, other phones, even Apple products, ONLY our MBPs can connect for some odd reason.
    Any ideas on solving this? Thanks...

    Done! I looked through some other threads and someone suggested resetting the entire AirPort with the reset button on the actual device instead of in AirPort Utility. Try that! Works completely fine now! Good luck

  • IMac suddenly can't see any wireless networks!

    I have a recurring problem with my iMac 20" Intel Core Duo.
    For some reason, it suddenly loses the ability to see wireless networks. The problem is resolved if I restart. I go through this several times each day, and the frequency of the problem is increasing.
    Strangely, there is nothing wrong with my Airport Extreme wireless network. My other computers see it just fine.
    And when I check the Airport indicator at the upper right-hand side of my iMac's desktop during this problem, it shows NO wireless networks at all! And I have 7 neighbors with wireless networks on 24/7!
    As I said above, the solution has been to restart my computer, at which point all the networks appear again.
    Can anyone offer a solution/explanation? I have tinkered with my network settings to no avail.
    Thanks in advance for any suggestions.
    MacBook Pro, iMac 20" Intel Core Duo   Mac OS X (10.4.9)  

    It has to be unrelated because I too have been having the same issue for the past 2 weeks. Actually it seems that ever since I reloaded the last iMac intel update (which I had to do to get my iSight to work again)
    I've been having this issue multiple times a day. I even moved my iMac thinking I had too much distance and walls between the router and the iMac.
    I know it isn't the router because the laptop in the house picks up a very strong signal all the time.
    I tried switching channels on the router (a linksys) and it has seemed to help a bit. I am now down to dropped signals only about every other day.

  • HT4628 My MacBook Air does not see my wireless network

    My iPhone and iPad Mini see the network and connect with no problem. However the MacBook Air doesn't see the network. I tried adding it manually and it still does not recognize the network. Any ideas what I can do to resolve this issue?

    I am having the same problem and it is still not coming up supposed to be plug and play and Mac friendly?

  • Need help here! I'm out of options. Computer can't see the wireless network

    Sorry for the novel, but I have to tell you what is going on with my computer.  I also need to vent because I’m extremely frustrated.  I want to make sure I give as much info as I can we can get this fixed.  I’m done with trying to figure this out on my own!!!
    I’m having a major issue with the wireless network connection on my desktop.  I’ve tried everything and I can’t figure out what it’s doing.
    First of all, my wireless router is set up correctly (according to the Sticky), has active security, and works fine.  It has nothing to do with the router.  I’m sure of it.
    Here’s a quick history:
    When I was at my first residence in Chicago and bought a Linksys wireless N router in May 2008.  My computer was about 30 feet away from the router and everything worked fine.  Always found the router and never lost connection.
    I moved to a new place in September 2008 and used the same router, computer, etc. at my new place.  The computer was only about 7 feet away from the router this time, but I used the wireless connection instead so I wouldn’t have a network cable lying across the floor.  At first everything worked fine.  No issues.  Then, one day out of the blue, my desktop lost connection with the router.  My router didn’t even appear as an Available Wireless Network.  I rebooted everything and that seemed to fix it.  OK, issue fixed, right?  Wrong.  It did it again the next day.  I rebooted everything, but it still couldn’t find my router.  It did see lots of other wireless routers in the area though so I know the wireless card was working.  It just didn’t see my router.
    This went on for a while.  Sometimes it would see my router and connect then it would lose it again.  I thought maybe it was the router going bad.  Well, I have a notebook computer too so I tried it.  It has found my router every time and has never lost connection.  I had it sitting on top of my desktop even to see if there was some sort of dead spot in my condo, but the notebook found my router just fine. 
    Sometimes my desktop would see my router, but it wouldn’t be my network name.  It would call it “Home” or something.  I know it was my network because it was the only network with maximum (Excellent) signal strength.  I’m thinking it must be some sort of association issue.  For some reason it doesn’t associate my router as an available network.  I don’t understand that.
    I tried everything: Ad Aware, Live OneCare, registry cleaners, driver updates, restore points, pretty much anything I found in the forums.  Nothing worked for long if at all.  It’s like my desktop only finds my router when it wants to.  Note: The only thing that would work sometimes was if I clicked “Repair.”  Sometimes that would work.  I finally gave up and connected my desktop via network cable and unhooked my wireless card.  I never lost connection as long as it was hard-wired.
    The drama continues.  I recently moved to Iowa and set up my network here.  I’m using the same router, same desktop and wireless card, same notebook computer, etc.  I went ahead and tried the wireless card on my desktop again.  It worked just fine!  No connection issues at all.  It connected and stayed connected.  I thought, “Well, that’s strange.  It must have been something with the condo in Chicago.  Oh well!”  It worked fine from February 5 until March 10.  Now it’s doing it again!!!!  The notebook is about 3 feet away and sees the router just fine.
    Here are the facts:
    I’m using a Linksys WRT300N Wireless-N router.
    I’m using a Linksys Wireless-N PCI WMP300N Adapter (about 18 months old).
    I’m running Windows XP on the custom built desktop and Windows Vista on the HP notebook.
    I built this computer about 5 years ago and have not done any major upgrades for 2-3 years.  The only thing I added was the wireless card.  I also changed out the HD in January 2009 and did a data migration right before I moved to Iowa in February.  All of the networking issues were going on well before I did the data migration though so it has nothing to do with that.  In fact, I had my computer hard-wired into my router at the time of the data migration and the wireless worked fine (for a little while) after I moved to Iowa.  So if anything, the data migration seemed to help with my wireless connection.
    All drivers are up to date.
    Using Windows Live OneCare and have run complete scan: nothing found.
    Using Ad Aware and have run complete scan: only found cookies and deleted them but didn’t fix issue.
    Ran WinsockxpFix but that didn’t help.
    Ran TweakNow RegCleaner Standard but that didn’t help.
    Right-clicking the wireless icon, I try to view Available Wireless Networks.  The window comes up and shows me other wireless networks in the area (2 available right now), but doesn’t show my network at all.  I click “Refresh network list” and 1 or 2 of the other networks will come up, but mine is still not shown.
    I’ve clicked “Repair” and get this message: “Windows could not finish repairing the problem because the following action cannot be completed: Connecting to the wireless network.”
    If I go to Control Panel, there is a Wireless Configuration Utility program from Broadcom.  When I open that here is what I find:
    It is not managing my wireless networks.
    Under the “Wireless Networks” tab I see my Network with an “X” over the router icon to the left of it and a locked security icon to the right of it.
    No information under the “Link Status” or “Statistics” tabs.
    The “Site Monitor” tab shows my wireless network and the other 2 networks in the area (although they drop in and out because of signal strength).  My network is always present even though the signal strength bounces up and down.  This tab shows that my network is secure, 802.11 is g and n, speed is 270 mbps, Channel is 9, and Signal bounces from orange/red to green.  Data encryption is (m)TKIP, TKIP, WPA-PSK.
    I was going to use my notebook to post this message since it has been connected for 2 days without ever losing connection.  It shows Very Good signal strength and is about 3 feet away from my desktop.
    Update:  My desktop just connected to my network after sitting there for 2 hours.  Good to Very Good signal.  Broadcom tool shows the connection and now has information in the Link Status and Statistics tabs.
    Cancel that.  It just lost connection again.  It was only connected for about 5 minutes.  There is no change in signal strength according to Broadcom though.  In fact, Broadcom shows better signal now that I lost connection.
    Now, it just connected again (on its own) after sitting there for 10 minutes!  I’ve been surfing the web on my desktop for 45 minutes now and I’m using my desktop to post this message.  What the heck?!!!  This is what it’s like.  Aggravating huh?
    Well, that’s all I can think to write.  What else do you need?  Can anybody help me with this?
    I’m confused.  Please help!
    Thanks a lot!!!
    Jake
    Message Edited by JakeT on 03-12-2009 02:54 PM

    Thanks but it's just my desktop that doesn't see it though.  My notebook sees it everytime, even at the same exact time that my desktop doesn't see it.  For example yesterday when I was typing up this post, I was typing up the post on my notebook because my desktop didn't see the router.  I don't think it has anything to do with the router actually, but I wanted to see if anyone on here has encountered this issue before.  Other forums have similar issues but I've tried all of the fixes I found elsewhere and they didn't work.
    Any other ideas?
    Thanks!

  • Airport extreme can't see any wireless networks.

    Hi, I have an iMac that has always used an ethernet connection to the internet, but now I want to connect wirelessly. But it doesn't seem to "see" any networks, mine or otherwise, which work fine on my other apple devices. Does the fact that my wireless card was purchased (as was the imac itself) overseas make it incompatible with US wireless networks? Or is the card broken and I have to take the computer in for repair? Or is there some way I can resolve it myself?
    Here is what my Airport card info says:
    AirPort Card Information:
      Wireless Card Type:          AirPort Extreme  (0x14E4, 0x88)
      Wireless Card Locale:          Asia Pacific
      Wireless Card Firmware Version:          Broadcom BCM43xx 1.0 (5.10.91.22)
      Current Wireless Network:          wireless network not available

    Yes, it does. Still doesn't "see" any networks. If I need a new airport card, is this something I can do myself or does it have to be done at an apple repair shop?

  • Ipad can not see any wireless networks

    So I updated my iPad's operating system last night, and my wireless connection to my home network worked fine. Now I'm at work (in a midtown Manhattan office building, where my laptop recognizes about 50 networks) and it can't see a thing.
    I don't have the ability to unplug the router, and at any rate this is clearly an internal issue as it's not missing one network, it's missing dozens. I've restarted, reset wifi, reset network settings, toggled airplane mode, etc etc etc. Any other suggestions? Inevitably, it's on an afternoon I have a major facetime appointment.

    Try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.

  • Officejet Pro 8600 plus 'seeing' duplicate wireless networks - and refusing to connect

    Greetings,
    I am running a wireless network that uses a couple of Airport Expresses to extend it.
    My other HP Printer (Officejet 8500) has no problem connecting to the same network.
    I am running MacOS 8.2 and have downloaded/installed 
    Officejet-Pro-8600_v12.23.0
    The Error Message = "Duplicate WiFi Networks Names...Plese check your wireless router settings. Click Change Networks to select a different network."
    Folks - I have only one network.
    The software is not smart enough to just choose the strongest signal and connect to it !
    Thanks for any suggestions...

    Very disappointed

    Good thinking !

  • Xbox 360 Can't See Extreme Wireless Network

    We had some AEBS problems today with several of our Macs not seeing the Airport base station. After much fiddling about, which really didn't amount to changing much, everything ended up working again. On one Mac we did do a software update to the latest AEBS software, but the other Mac seemed to cure itself.
    Anyway, all Macs are working fine now. But my son's Xbox 360, which was working (seeing my network and using the Xbox wireless adaptor) is now not giving my network as one of the choices it finds in the Wireless Network Screen. We have restarted the modem, the 360, etc, nothing. We typed in the name of the network with the WPA password manually into the Xbox and still nothing.
    Any ideas?
    Thanks
    Tom

    xbox360 try 'other" to find the network and occasionally I had to change my security from wpa2 to wep then back.

    Two things I'd check first:
    1 - in your router, do you have mac address filtering turned on? If so, add the mac address (Airport id) of your MacBookPro to the 'Wireless Station Access List' in your router. You can find your Airport id under *System Prefs > Network > Airport > Advanced > Ethernet* .
    2 - in your MacBookPro, turn Airport OFF. Then go into *System Prefs > Network > Airport > Advanced.* In the Preferred Networks box, delete the wireless network you are having trouble authenticating with. Click OK, then Apply. Exit System Prefs. Then turn Airport ON. Find the network; re-enter your password. See if that fixes things.

  • I can connect to my wireless network but not the internet

    Hi. I've had my iBook G4 for just about a year and it's worked fantastically... until recently. My roommate has a PC and a linksys wireless router, and I've always been able to connect wirelessly to the internet until last week. I came home from work one day, and my iBook "saw" our wireless network and could "see" other computers on the network, but could not access the internet. My roommate had no problem accessing the internet through the wi-fi on his Dell laptop. So I zapped my p-ram and fiddled with some settings, but I still had the same problem.
    Next I re-installed OS X, and tried again. Still the same issue. Of course, by this time I'm getting frustrated, but then about 12 hours later I decide to try it again and it just works! Like there was never any problem....
    So anyway, it worked like a dream for about a week and now I have the same exact problem again! It connects to the network but not the internet. Is this a known problem? Any help would be GREATLY appreciated.
    Thanks,

    i was having the same issue with all my devices. everything would cut out and i would have to reboot my router...my internet service provider is ATT and i have a Uverse router. i went to their online support and i was able to chat with a tech support agent and they ended up changing the channel of my router and that has resolved my problem....i am currently steaming pics from my iphoto library to my apple tv and my wife is streaming music from her iphone at the same time...support tech stated that usually they have the router set to a generic channel that usually has a lot of traffic.
