MacBook pro can't find any wifi networks. HELP PLEASE

Ok so my late 2011 MacBook pro15" starTed dropping out of my network every now and then. Rebooting it got it hooked back up again. Now just a few weeks ago its not picking up any real wifi networks (according to my phone and what my computer showed me before there's a bunch in range). It shows this network called setup as the only wifi network in range and when I click on it, there is this little grey picture of a computer where the wifi bars should be.
Xbox,  phone and all of the roommates devices are hooked up just fine.
I've taken it out to a couple of coffee shops and its the same thing.  Either seeing no networks or that setup thing.
I've tried restarting,  verify and repair disk, deleting all of my preferred networks.  I don't know what else to do. 

Also I've tried to use one of those usb WiFi adapters that essentially bypasses the computers airport card.  That shows all the networks in range but will fail to connect to any of them.

  • Macbook PRO can't find ANY Wifi network - only at home

    Hi, i have a very strange problem with my *Macbook Pro*. I have 3 apple computers at home and one pc. On all machines Wifi works fine, except my new alu Macbook Pro. Important note is, when im with my macbook on other place, office, caffe, *Wifi works fine. But when im at home, this macbook simply can't find ANY network, it's blind.* Interesting thing is, all other computers are several years old and WiFi works fine on them. My friend also bought a brand new macbook pro, and this machine also couldn't fine any network at my home, or in other case when it found networks, it couldn't connect and recieve error message "Connection timed out". I noticed there is new Wifi network in our range, is it possible that this network can cause "blindness" on new macbooks?

    *I have to say, I'm really glad you are trying to help guys.*
    Well, router is almost on default settings, SSID is brodcasted and i'm not filtering MAC adresses. I tried changed channels, diffrent types of security or no security, no luck.
    Guys, maybe i wrote it wrong, but this MacBook can't see ANY network. Around me there are 4-6 other networks which I'm able to see from other machines. So *problem is, this Macbook can't seen ANY network - not just mine.* BUT when i'm with this Macbook in office for example, or any other location, Wifi works....
    And one more important thing, this happened suddenly. I was able few months ago to find any WiFi around me with this Macbook. No changes to router, no changes to mac. Problem is somwhere in the middle...try to focus on this: why i'm not able to see any of those cca 6 networks around me. I really think it has to do something with distorted signal and Wifi card used in new macbooks. It's really sick, because all other machines works perfectly (MB 07, MBP 06, PC, iPhone 3g)
    I found a log on the router, and it's happening all the time:

  • After I connect with my iPhone (3GS 5.0.1) to any Ad-hoc wireless Network then walk away out of the reach of my wifi network, my iPhone can't find any wifi Network afterwards, only by turning off the iPhone completely and turning on again.

    After I connect my iPhone (3GS 5.0.1) to any Ad-hoc wireless Network then walk away out of the reach of my wifi network, my iPhone can't find any wifi Network afterwards, only by turning off the iPhone completely and turning on again.
    switching off wifi and on again or going into airplane mode did't help!
    This problem happens only with ad-hoc wifi networks not with normal ones.
    (Ad-Hoc network was created on XP Computer)

    Welcome to Apple Discussions
    Sorry, but the 169.x.x.x IP address is internally generated by the iPod (and iPhone) and indicates that a network has been detected but no IP address has been issued. Your friends iPhone was not connected to your ad hoc network either - it connected to the internet through the 3G network.
    You should read through the Vista help screens on ad hoc networking for some insight how this works. You should be able to get some ideas there.
    In the mean time, $40 or less will buy you a very capable wireless router with four Ethernet ports and will simplify your network tremendously. Having used Windows ICS for a long time, the addition of a router and a real network simplified things so much.

    Change your router channel.  Sometimes this is all you will have to do.
    Power cycling the router.  Read the router's user manual or contact their tech support for instructions.
    System Preferences/Internet & Network/Network
    Unlock the padlock
    Locations:  Automatic
    Highlight Airport
    Click the Assist Me button
    In the popup window click the Diagnostic button.
    System Preferences/Network- Unlock padlock.  Highlight Airport.  Network Name-select your name.  Click on the Advanced button.  Airport/Preferred Networks-delete all that is not your network.
    Place a check mark next to "Remember networks this computer has joined."  Click the OK button and lock the padlock.  Restart your computer.

  • HT1695 Can't Find any wifi Networks after updragding to 6.0.1

    My iPhone 4 can't find any wifi networks after upgrading to iOS 6.0.1 and i can't downgrade what should i do ?
    I swtiched off  the connection from mobile and restared the router and nothing changed!
    Note: My laptop found about 7 Networks my iphone finds nothing

    I have the exact same problem.
    It popped up on my 8gb iPhone (2.0.1) first time when i just purchased it. The Wheel spins as if it's searching for hotspots (and there are a lot of hotspots where i live). My MacbookPro finds them without any problems.
    Second time i experienced these problems, it was after i didn't have a chance to charge the phone, and i figured it was a "Low battery, disable wifi" thing. But even though i charged it fully, it still can't scan networks.
    I managed to discharge the battery, until the 10% warning popped up. I connected the charger, and sure enough, it was able to scan networks. Then when i tried to join a network, it stopped working again, and since then i've been unable to scan wifi. Now 3 resets, and a lot of fiddling later, i'm no further than i was before.
    The fact that it was able to scan momentarily points me in the direction of the software, but i'm not so sure anymore.
    Hope someone can shed some light on this.

  • IPad can't find ANY wifi networks or personal hotspot each time I return to my home network

    I have an iPad 2 as well as iPad 4, iPhone 4 and Macbook Pro. Each of these connect fine to my home network, however my iPad 2 suddenly couldn't find any networks or my iPhone 4 personal hotspot, bluetooth or wifi.
    I went to Singapore and hey presto, it could find and connect to wifi networks with ease.
    Then I came home to Australia, couldn't find any networks or personal hotspots again. Went to work, same issue, couldn't find the network at work. So took it to the Apple Genius Bar and it worked automatically again without changing any settings. Reset to factory settings just incase this somehow helped getting it home.
    Took it home, worked fine. Recovered from a previous backup and still worked fine.
    Brought my ipad into work yesterday, couldn't find my personal hotspot or wifi networks. Took it home, can't find any networks. Reset my modem and it still can't find any networks (or my personal hotspot) even though all other devices automatically connect.
    Any suggestions? I suspect when I take it to Japan next week it will probably work fine, then I'll come home and it probably won't. Is it some sort of software issue? Why would it stop working every time I take it out of my home network and bring it back?
    I have all the latest updates.
    Thanks in advance and reading through!

    Does the ipad have any management software put on by your workplace ? If so this my be somehow disabling your wifi. The other thing it may be is the wifi channel your wifi is broadcast on but as it happening to you with a lot of access points it prob isn't this it may be a hardware issue, you could take it To an apple store and if it works there try connecting it to your phone. You could also try this, go to general > one of the last options (between VPN and reset) is profiles (This only shows up if u have profiles installed) if you have profiles go into it and delete the profiles then restart. this may help. Good luck

  • MacBook Pro Can't find home wireless network

    I've been having some issues getting my macbook pro, running OS 10.7.5, to find my home wireless network. The network doesn't show up when it searches automatically, and when I type the network name in to find it manually, it says no network found. The computer connects to all other networks and finds then with no issues, and other MacBooks are able to find my home network and connect to it again with no issues.
    The computer used to be able to find the network, and then it just stopped working. I have tried all the standard fixes, resetting the router, computer, PRAM, forgetting the network, deleting the key from keychain, but nothing seems to work. I tried googling the issue, but wasn't able to find a problem similar to the one I have.
    Any advice would be greatly appreciated.
    Thanks

    Still having problems with this.
    I have upgraded to Mavericks, hoping that the problem would be fixed, but it hasn't. I still get all networks completely disappearing - even if I search for them they are not found.
    But I reboot the computer and it works! But when I am in OS or Bootcamp mode and put the Mac to sleep, it does not see the networks again! I have to reboot the computer for it to work.
    I have even got a new router which can receive the b,g and n signals etc. as I was told by a Mac techie here that Macs 'look' for the n signal but can also work with the b and g signals and THAT maybe my old router only transmits b and g or something like that .
    This, to me, sounds like a Mac software problem. I had a similar problem on a previous Mac on my "old router" and a totally different router in a different country's telephone system.
    I now have the same problem with a new MBP on a new router!

  • IPhone can't find any wifi networks

    I have an original iPhone. It originally ran on wifi networks and Edge, but for a while it has only worked on Edge. When I look under settings - Wi-Fi it says "Not Connected" and lists no networks. My MacBook is connected wirelessly via an AirPort and the wireless info on it lists at least 5 active networks in the area. I have tried toggling between Airplane Mode and not, turning off everything (including cable modem and AirPort) and then resetting network settings, resetting all settings, and erasing all content and settings. I have also tried "Other" under Wi-Fi Networks, but it can't find my home network.
    Is there just something wrong with the device?

    I have the same problem you did. Was your phone still under warranty or covered under Apple Care? My phone isn't under warranty anymore, so I'm just hoping that I'm not out of luck.

  • My Macbook Pro can't find any of my files!

    Hi there,
    Since yesterday, my Mac suddenly can't find any of my files anymore. All the folders are there, but all the files are missing. There are 2 big question marks on the top of the finder window and when I click on them it says that files cannot be found. I have no clue what to do now. The only thing I did before this happened, was deleting my downloads folder, but nothing more. It's weird that all the folders are visible but the content not. Anyone experienced this too? What can one do in a case like this?
    Thank you for any help!
    Raphaela

    Did you run a disk check on it? You might have data corruption. The big question mark on the top of the finder window, I believe is a short cut, not the actual file. Did the actual file move? Did you rename the file? Did you change anything, like your username? Did KIDS use your machine? KIDS can do some silly stuff to your computer without even realizing it. I know this option may sound OFF BASE, but do you have a faulty trackpad, or use excessive hand lotion? (I have seen both of these cause undesired file moves, renames, etc...)
    I would run a disk check, and if available, use Disk Warrior, Drive Genius or similar to rebuild the directory.
    If that does not help, I would search for the file using Spotlight, or a 3rd party app like Find Any File.

  • My 13 inch Macbook Can Not find ANY wifi networks! Help!

    I turned on my Macbook today only to find that no wifi networks are showing up, not even the neighbors! Im connected to the eather right now. My roommates laptop PC can connect fine. I need some help fixing it. Why is it not finding ANY networks at all?

    Open System Profiler and check if the compter can still recognize your wireless device. Try resetting the SMC as well and see if this helps.

  • My new macbook pro can't find my Belkin network

    My new Macbook Pro is recognizing all sorts of newtorks in the area except the one in my home.  I have a Belkin N+ wireless router which I know is working because two other computers (pc) and my wife's iPad are having no problems connecting.  This is a frustrating start for a hesitant pc-->mac transition.  Any help will be greatly appreciated.
    Jim

    Just finished trying the suggestion from my Mac store "genius", and it WORKED.  He suggested that I connect to the router directly with ethernet.  His thought being that once my MBP found the IP address it would be able to find the network wirelessly.  While still connected I went to System Preferences/Network, selected WI-Fi and entered the network info (name & password).  There it was - connected.
    Don't know how to make this solution available to everyone with the same problem.  If someone knows how, go for it.
    Thanks to everyone who responded.  Your efforts are appreciated.

  • My iPhone 3G iOS 3.1.3 can't find any wifi network.

    I have nothing changed. neither the iPhone nor the Network. no Update anywhere.
    There are several wifi hot spots around my home, but my iPhone doesn't show any wifi.
    I have wifi with my iMac, iPod and all other devices.
    I can't connect to any specific wifi network.
    Shut down and start up doesn't help.
    Resetting all connections doesn't help.
    iOS: Troubleshooting Wi-Fi networks and connections doesn't help.
    Maybe it is a hardware problem, but I hope there will be a software solution to solve this problem!

    I Just purchased an original iPhone and "couldn't search for wifi" kept popping up. I have the airport time capsule 2013. Tried firmware restore and everything else I could glean from the internet. Wouldn't even find any of the neighbors? Decided it was broken. Middle of night I thought?? WPA2?? First thing this morning fired up my Cisco Valet Plus router, changed the security to WEP and voila, it works like a charm. I don't think I'm going yo change my settings on the Airport Extreme, since the phone is only nostalgic. This could easily be the problem on any iPhone running 3.1.3..

  • Macbook pro can't find preferred wireless network

    My father signed onto my wireless network using his own laptop (PC) with my passkey.  Then after he had been on I tried to connect to the internet with my macbook (and iPhone) and my network was gone.  If I look at the list of available networks it lists my neighbor's (which usually doesn't happen) and the name of my father's computer but ours is gone.  If I go to my preferred networks, I see mine listed but then when I try and connect to it is says it cannot be found.  I tried creating it again but then when I enter the password it says it's invalid.  I tried connecting to the network under my dad's computer's name to see if somehow the name changed on its own but it says invalid password as well.  Any ideas? 

    "If I look at the list of available networks it lists my neighbor's (which usually doesn't happen) and the name of my father's computer but ours is gone."
    Your father's computer should not be showing up in the list of networks unless he mucked around with your router. Log in to your router's admin pages and see what the issues are.
