MacBook Pro: No Wi-Fi Networks Appear

Hi there. I have a bizarre networking issue I'd love some insights into.
I'm unable to see or connect to any wireless networks with AirPort enabled. I have a 15" MacBook Pro (early 2011 model) running OSX 10.8.5 with 2 GHz Intel Core i7, 8GB RAM. I've tried:
Turning AirPort on and off
Checking the router (it works with other computers)
Going to a public place with public wifi
Restarting
Zapping PRAM
Reseting SMC
Deleted plists, including: com.apple.internetconfig.plist, com.apple.internetconfigpriv.plist, and com.apple.internetconnect.plist
Under System Information, the network card shows up as AirPort Extreme, firmware Broadcom BCM43xx, status: Not Associated.
Here's the weirdest part: After zapping PRAM, AirPort displays all the available networks and can connect to one! The problem is when I then put the computer to sleep and try to connect again, or go somewhere else to connect to a different network, at which point no networks appear in the list. So the card works, for awhile.
Does anyone have any thoughts? Much appreciated.

Hey i just had the same problem with my Macbook after searching and googoling for a solution i was about ot reinstalled the whole system again but, what i did to solve the problems was to re start the the mac and when the start up sounds comes up I pressed the option key and hold until the hard drives appeared i selected the recovery disk, i click on it as soon as it openned I saw all the available wifi networks around my house right on the right upper corner i did not do anything else so i re start the mac and login in in my account and there i was back connected to my wifi again.

I've also installed the 10.8.5 supplemental update that came out on the 3rd. As far as I can tell, OSX is completely up to date.

(This is a report of a question I asked two days ago. I thought the suggestion to install the supplemental update had solved the problem, but then it reappeared.)

Hi Nik P
It is bizarre and all signs point to a potential hardware failure. You might try running Apple Hardware Test but it is likely to report "no trouble found".
Though it is not likely to reveal an obvious cause, consider running EtreCheck in accordance with the following. It may indicate something that warrants further investigation:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.

Hi, when powering up my macbook pro, when the apple symbol appears the screen flashes pink, can anyone advise whats up?

You can try a system reinstall:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Im completely new to Mac. Im swapping my windows laptop for macbook pro and looking for network storage solution which the Time Capsule seems to do. Is it possible to use this as NAS for my desktop Windows PC - windows 7

Im completely new to Mac. Im swapping my windows laptop for macbook pro and looking for network storage solution which the Time Capsule seems to do. Is it possible to use this as NAS for my desktop Windows PC - windows 7

Broadly speaking I want some sort of network storage( wireless or through my existing wifi router) that I can access files for both my windows PC and Macbook and also to access files to my iPad/ iPhone. Some sort of backup and sychronisation so that I can access certain files remotely.
Buy a real NAS.. synology or QNAP are the standard... although companies like Netgear and Western Digital and Seagate make them as well.
There is no problem sharing between Mac and PC now.. you do not even need a NAS to do that.. you simply share the hard disk directly. Mac talk SMB.. everything talks SMB nowadays.. so it is easy.
ipad and iphone are not designed to use NAS.. they are designed to backup only to the cloud or itunes.. but you can load an app like file browser if you want.
http://www.stratospherix.com/products/filebrowser/
Remote access to the Apple TC is somewhere between difficult, to impossible from a PC.. Apple use BTMM and iCloud but the service is not offered to PC.
A real NAS will offer HTTPS or SFTP or several other methods.. that both Mac and PC can use.
You simply plug it into the current wireless router.. it is a network device and assessable over the network. It is not necessary to buy another router.. in fact that is a waste.

My macbook pro shows some wifi networks, but not mine. i dont know whats wrong, the wifi networks works on my phone as well as other laptops.

Macbook Pro retina have a network problem that I need to restart my computer before getting it's able to connect to internet

Macbook Pro Retina 15" 2012, Mountain Lion OS pre-installed.
Case 1:
It connects to WiFi home network and internet fine.
Put the machine to sleep.
Upon waking up, it can scan for my home network that it used to connect to, but either not able to connect, or even after it connects, it just can't let me access internet.
Restarting the machine can revive by getting it connects properly to internet.
Toggling the Bluetooth won't help here.
Case 2:
It connects to network using USB ethernet adapter.
Same case, everything works fine before sleep. After sleeping for some time, it's not able to connect to the internet any more unless I do a restart.
It's able to access local area network though, as I'm able to see some local network machines in my Finder window. Yes, I clicked on them and able to connect to their share folders. But just can't get through internet.
OS Problem? I'm not able to roll back to other OS, I swear I don't want to go through that painful process.
Hardware problem : WiFi card? Don't think so, because I can't get to internet even I immediately switch to USB ethernet adapter.
Hardware problem : USB ethernet? It works fine in other non-Mac machines.
There got to be something wrong in somewhere that it doesn't re-establish the connection to the internet, no matter what I do.
None of the functions in the network utility tool can help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Seeing Vista PC folders from a MacBook Pro on a wireless network

I have a 2 PCs running Windows Vista and a MacBook Pro. I also have Time Capsule. The Time Capsule is connected to my main PC by Ethernet cable and to the MacBook and my other PC wirelessly.
I share my Internet Connection with my PCs and Mac which works fine. I use Time Machine to back up my Mac - which works fine. I use Windows OneCare to back up my main PC via Ethernet onto the Time Machine as a hard disk - which also works fine.
My PCs and my Mac are all set up to connect to my home wireless network. I can see both my Macintosh and my wireless PC from my main PC as networked locations and can navigate to sub-directories, folders and documents on my Mac from the main PC and to shared folders on my wireless PC. I can also see shared folders on my main PC from my wireless PC.
However, I cannot see how I can do the reverse operation and access shared files and folders on my PCs from my Mac. Neither the main PC nor my wireless PC appear as shared locations in Finder and I don't know how to use the Mac equivalent of Windows Explorer to navigate via the wireless network to my PCs. Can someone advise please?

I was able to do it using my router.
On my netgear router (it has a very simple webbrowser-based setup and maintenance system) had the options to assign and reserve a particular ip address for each device connected to it. (It did this not by the computer name but my the MAC address of the network interface. Eg. My powerbook's airport card ALWAYS has an i.p. address of 192.168.0.7, whereas if I connect my powerbook via ethernet, it uses 192.168.0.2)
These could have been any ip addresses that I wished for. These two just happened to be the next available ones.
You should look at your network's router or switch's setups/manuals etc to find out if you're able to do this with your particular hardware.
I use just a simple modem/router/wireless access point all rolled into one:
http://netgear.com/products/details/DG834G.php
If you're working in an office environment, the hardware will probably be of fairly good standard, and therefore should allow you to do this.
Glad I was able to help a little with my last message, keep replying untill we get this problem sorted out.
DAN
P.s. I have just had another little look at my VNC (realvnc) server software. In the configuration of the server, in the;
"allow connections from local computer only and" section of the options I have got my two ip addresses (my ethernet and airport ones) stored to allow without needing confirmation.
This MIGHT be another way to solve your problem. But again, it all resorts back to you needing static ip addresses, not dynamic ones.
Let me know how you get on!

MacBook Pro forgets its wireless & network internet settings...

Hi...
I'm having problems with my MacBook Pro 'remembering' its wireless and network internet settings. I'm connecting via Airportto my Belkin 54g wireless router which is what has been running happily for the last 18 months.
Here's what happens - AirPort says it's connected, the internet works fine but when the MacBook Pro 'sleeps' or is restarted it 'forgets' its network and internet settings and cannot log on to the internet.
I get the Network Diagnostics appearing and I go through the options and eventually Network Diagnostics will show everything is fine, except there is no internet connection. I click through next options available on screen and I manage to get the MackBook Pro to restore its internet connection. All is fine until the MacBook Pro goes to 'sleep' again or is switched off.
This hassle began out of the blue - I haven't changed any settings on the machine, I haven't installed any software or anti-virus programs - it just spung up!
Any help or advice is greatly appreciated!
Thank you in advance!

Hi,
I have not encountered this particular problem yet, but I have just bought a Belkin 54g adsl and wireless router. It has connected up to my home pc with no problems and it has also connected up to my macbook pro (leopard) okay, but the range on the internet connection is really poor. It works up to about 50 feet, but I can't use it upstairs, which granted is more than 50 feet away from the source, but at 80 quid I thought it would perform better.
I contacted Belkin support which is local rate and they suggested changing the wireless channel from 11 to 6, but when I did this it would even find the network using Airport.
I would like to be able to use the laptop over 50ft (i.e. in my bedroom) as well as all over the house, but so far I only get as far as the next room!
If anyone has any suggestions I would be grateful? NB: I am not a very technical user.

My macbook pro won't recognize network printer

Macbook pro is late 2011 running OSX 10.7.5 - Lion, connected wirelessly to home network with airport express.
Have an HP deskjet connected with a cable to a MacMini mid 2011 - Yosemite.
macbook always has problems printing to this printer on home network. "printer not found" or "printer not connected"
Normally I turn off the printer and back on and it will print. Now I just get message "printer not connected"
I deleted the printer and tried to add it back and it will not find the printer.
Is it possible to reset the airport express? Will it benefit me? Is the issue that yosemite and lion do not get along?
I really would like to be able to print from the macbook without having to unplug printer and plug it directly to the macbook.
Frustrating to say the least!!!

I had almost the same thing happen the other day - kept getting a message that my printer was not connected. I went to the printer setup on the printer's panel and the IP address was correct, everything looked as if it should be working. So I just reset my router - figuring that would fix the problem. No go. What I finally ended up doing was resetting my router to factory settings and setting it up anew.
And that's what worked for me.

Homeshare worked on my PC until recent iTunes update. Cannot get homeshare to work on PC as previous. When I use my MacBook Pro on the same network, iTunes/AppleTV works just fine, so it has to be iTunes?

An interesting observation...when I have a MacBook Pro connected and select Computers on my AppleTV2, the name of the MacBook computer comes up on the screen and allows me to select it and view photos from my iTunes library. Orks perfectly. When my Windows 8 PC is connected, and I select Computers on my AppleTV, the name of the PC does NOT come up on the computer list, but instead the AppleTV immediately tries to download pictures from the PC itunes library. It runs for ~2 minutes then generates an error message saying it could not connect to the iTunes library and to make sure it is tunrned on, connect to the same network, and use the same blah, blah, blah. I know all the settigns on the network are correct because my MacBook works perfecty. So frustrating that my PC worked previously before the recent iTunes software update. What to do to fix it?

Hi Rickgal,
Thanks for visiting Apple Support Communities.
Based on the information, it does sound like this behavior is isolated to your PC. I recommend trying the troubleshooting steps in this article on your PC:
Troubleshooting Home Sharing
http://support.apple.com/kb/TS2972
Start with turning Home Sharing off and on again, as explained in step 3:
Go to File > Home Sharing and choose Turn Off Home Sharing.
Choose File > Home Sharing > Turn On Home Sharing.
When prompted, enter the Apple ID you'd like to use.
Click Turn On Home Sharing, then Done.
Best Regards,
Jeremy

Macbook pro can't find network

previously, i was able to print using a shared printer using my macbook pro. the printer is hooked up to my home desktop and there was a network connection that allowed me to print from my macbook. just recently i realized it wouldn't let me print and i came to the conclusion that it wasn't letting me print because it couldn't find my home network. i find that weird because i still have internet access but for some reason it won't find the shared printers or files. i know i am not very descriptive so if you need more information please let me know and i'll try to explain to the best of my ability. help would be much appreciated, thank in advance!

From the sharing Mac uncheck the Printer sharing for a minute and then check it again. Strangely enough this fixes a lot of people.

Connecting HP Laserjet 1010HB with Macbook Pro via D-Link Network!?

Good evening,
I have a MacBook Pro and I want to be able to print via WiFi.
The Printer is hosted by a Windows Computer via D-Link Router Network
My sister who has a Windows Laptop is able to print.
I read about Bonjour but this seems to be a software for windows computers
to print with a Networkprinter hosted by an Apple-PC.
I need exactly the opposite.
Host: Windows 7 (D-Link Router DIR-655)
Me: OS X 10.6.7
I tried to use Shareport Utility but without success.
Shareport doesn't show the Printer.
 > system settings > print and fax > + > doesn't work. What settings should I use? LPD, IPP, HP Jet direct socket.
And the driver: We got a HP Laserjet 1010HB -> HP Laserjet 1010, HP Laserjet 1010 v2 Gutenprint, HP Laserjet 1012, v2 1012 gutenprint.
How ever I don't know what to do.
And I will certainly NOT buy any additional Airport thing of Apple or they can **** ***** ****** ** ***** **** and I will **** ***** **** ****
Hope you can help me.
cheers

Thanks for the feedback LilyLC. I too have gone through all of your steps and a host of others. Still with no luck. No problems at all with my Airport Express, but still no way to keep up a connection with my DIR-655 via WIFI N. I tried all of the steps with each firmware version too. I've given up at this point. I want the 2 months of my life back that I spent troubleshooting this mess. At least Apple could acknowledge this and say we are on it, and that it isn't only "in our heads."
/begin rant/
I think that Apple needs to do some re-evaluating of their software release schedule/quality control. At this point I would rather wait and have them get it right then put out subpar updates and fall into the downward spiral pattern of "the rest of them". My confidence has been shaken and I've been a mac fan since the beginning. I just want Apple to split off the iPod/Phone/TV etc. into its own division and to get back on track with the Mac line starting now. We need this stuff to work to make a living and this takes a higher priority in my mind than new twiddle apps on the iPhone.
I do own two iPods and an iPhone but would chuck them in a river to get Leopard working solidly with the majors like Adobe, Extensis, Epson, as well as stable networking, syncing and backups. Apple really has their hands full at this point with a large list of bugs. I really wish them well but can't say I'm in the least bit happy as a consumer at this point. For the first time in a long time I feel sheepish when answering whether or not I'd recommend a Mac, and that hurts me deeply for some reason.
/end rant/

Can I connect my MacBook Pro to an existing network using Airport Express?

I live on a sailboat that is about 225 feet from the marina's network antenna. I receive a strong signal on my boat but can only occasionally connect from my cabin and even then, the connection is very slow (I am pretty certain that my MacBook Pro just does not have enough signal power to get back to the network antennae). If I move 50 feet closer the connection works well. I tried to configure a range extender but nobody has any technical information on the marina's network. Does anybody know of a way to for my AirPort Express (or any other product with greater range) to connect to their network and then by cable (or wireless) to my MacBook?

DeltaDawg, Welcome to the discussion area!
There was a similar question but using an AirPort Extreme base station (AEBS). Unfortunately the answer is the same.
No, that is not possible. The Ethernet port on the AirPort Express (AX) is ONLY active when the AX uses WDS to wirelessly join a network. Unfortunately very few (less than 7) 3rd party devices support Apple's WDS. Also this requires configuration changes at the base station creating the network and the AX.

Why does my macbook pro forget the wifi network when i only set the iPhone to forget it?

i just dont get. what is the logic behind the mac synchronises network access between devices? i set my iPhone to forget a certain wifi network and now my macbook pro also forgot it, so i had to reset my router for this. pretty annoying. any workaround if i want iCloud to keep my passwords synchronised but not sure up the network access instantly on all devices?

I had to call Apple and the tech made me enter a bunch of terminal commands to fix this. Unfortunately I can't tell you excactly what it was. I think the best way would be to call Apple.
