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.

Macbook pro won't connect to wireless network

hi, hopefully somebody could give me an advice!
i purchased a 13.3 inch macbook pro yesterday and i'm in love...except for the fact that it will NOT connect to my wireless network. i have been using a linksys WRT45G version 6 router for many years with no problems (currently have 3 computers linked to it - all pc's). i've updated the firmware but still no luck.
the macbook pro is able to see the network but can not join - it gives me a generic "connection failed" message when putting in the WEP password. i consider myself to be techno-savvy, but not with macs! i'm completely lost and equally frustrated. help, please!

Hi guys,
I seem to have a similar problems. It is starting to occur this afternoon and somehow i cant fix it.
I have just installed my Snow Leopard about 3 days ago... and it was working fine. This afternoon I had a problem with my modem, but after resetting it about 3 times it was working fine again. So i tried to connect to it wirelessly but it kept saying 'connection timeout'. It becomes really annoying at the point of resetting the modem to its factory default settings. But then, i tried using the ethernet cable. It seems to be working fine for now. I tried connecting it through my home computer 'wirelessly' and it seems to be working fine. What I am wondering now is that, why doesn't my MacBook Pro connects wirelessly? Anyone has any idea?
PS: I have tried changing the channel of my modem and it doesn't do much.
Thanks

MacBook Pro cannot connect to a wireless network

I am having the following problem with my MacBook Pro trying to connect to a wireless network using a 2WIRE Gateway wireless Router from Bell that worked perfectly until last night. My network preferences pane is saying "AirPort has the self-assigned IP address 169.254.227.XX and will not be able to connect to the Internet." I'm not a techie and I've tried everything I know and cant get my MacBook to connect to the internet using the wireless network in my home. I'm using ethernet connected directly to my router for this! It's killing me. Any help would be greatly appreciated.
Thanks in advance.

OK. The wireless network was selected. In the Preferences / Network pane I removed Airport by selecting it and hitting the - button and then created a new Airport by hitting + and selecting Airport. I'm getting the same result. Full network signal once the ethernet cable is connected. Greyed out icon with ! once I remove the ethernet cable and no internet. I appreciate your help so far. Any other thoughts? We also have an iPad, iPhobe, iPod, and two iMacs on the same network. All of them are connected no problem. My Macbook also still connects to the network in my workplace no problem. This all just started happenening yesterday and I don't believe I changed or upgraded anything. I just came home and it had stopped working.

MacBook Pro won't connect to wireless network unless tilted

Hi! My MacBook Pro occasionally has trouble connecting to the wireless network in my house, but that can usually be solved by turning Airport off and then back on. Today (very suddenly), Airport disconnected from my network and could not find it again. I tried restarting my MacBook Pro and router multiple times. Finally it was able to connect, but here's the thing: it only works if my MacBook is tilted at an angle. If I try to open a webpage while the MacBook is sitting normally on a flat surface, the page won't load. If I lift one side of the MacBook so that it's tilted at a 45 degree angle, the page will load. Once it's level again the internet will stop working and the Airport signal bars will turn gray.
I've never come across a problem like this before. Everything was running fine this morning. It is so strange and I have no idea what to do! Help, please? Is my Airport dying? Is something loose inside? My MacBook Pro is about 4 years old.

Delete your network from system preferences, network, advanced.
re enter your network you wish to join
If that fails then do a PRAM reset

and a SMC reset

Maybe something to do with the motion sensor
if so try resetting the SMC

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!

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.

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.

Macbook Pro Doesn't connect to Wireless network automatically

I just enabled WPA encryption on my router and now my macbook won't automatically connect to my router. I have to select my router in the wireless menu and then it joins. I don't have to type in my encryption key, I have my key stored in my keychain. Before I enabled encryption my macbook connected just fine. I'm have 10.4.11 and a D-Link DIR-655 router.

Could be a corrupt preference file. Not sure which one is relevent here. It may just come under the general Finder prefs. Have a look in User>Library>Preferences for anything wireless related. If nothing shows, try dragging com.apple.finder.plist to the desktop, then either relaunch the Finder or log out and back in. If no change just put it back and choose 'replace' when asked. If you find something more appropriate try that too. Not at a Mac right now otherwise I'd be a little more helpful.

New MacBook Pro not connecting to MOST wireless networks

Well I'm another loyal sufferer, 10.5.3 did nothing to solve the problem. After reading a bunch of posts however I think i have a bit of a unique situation..
I'm staying at a condo for the next two weeks without internet, so i poach it from my neighbor, it's fine he said i could. I had a PC and that connected fine, fast too, when i got my mac it worked for a few days then crapped out, gave me the "self-assigned ip address' message of death. I brought my Mac to work and it worked fine on the company's internet wireless (it's an 801.x security) so after work i took it home and it worked for a day. The next morning, same problem.
I took it to starbucks, said it was connected but wouldn't open any pages in firefox and wouldn't connect to messenger. Back home now it says i'm connected, I can get into the router settings and play around with it, nothing has worked thus far. I did a ping test and it's working fine, what's the problem?
For the record i have tried the following:
turning airport on and off then restarting
Clearing airport preferences
removing and reinstalling the OS
clearing keychain
trying every possible advanced option, manually entering IP's etc.
doing the safe boot, restart and normal boot.
I hear switching the router to 'g' only is the way to do it. I'm going to try that tonight because right now I'm just concerned about my internet connection at home, it works fine at work.
Any new insight is greatly appreciated! I'm dyin' without it!

You probably connected but failed to get an IP address. If you have other network devices turn them off, restart the router and see if you can get access to the Internet then. Otherwise click on the network diagnostics button (or which ever appears in Safari's failure) and see if it'll give you clues.

I have just acquired an iMac desktop. I want to sign on to my airport wireless network, but cannot remember the password. How can I access the password or reset it. I already use a MacBook Pro and an iPad on the network.

I have just acquired an iMac desktop (about 4 years old). I want to connect to my Apple airport wireless network, but cannot remember the password. How can I access the password or, if necessary, reset it. I already use a MacBook Pro and an iPad on the network and don't want to jeopardize what already works well. I am not all that computer literate.

How can I access the password or, if necessary, reset it.
Read the user manual that came w/your Airport router or you can cross-post in one of the AirPort Forums for instructions.

TS3297 Is it possible for itunes on my MacBook Pro to play songs off my networked WD external hard drive and sync to my iPhone? I prefer to not keep all my music on my laptop and I don't want to pay $25 a year to access my songs if I don't have to.

Is it possible for itunes on my MacBook Pro to play songs off my networked Western Drive external hard drive so I can sync to my Mac to my iPhone? I do not want to keep any music on my laptop and I don't want to pay $25 to itunes match a year to access my songs if I don't have to.

Hi turingtest2,
Thank you for replying. I've been looking at your posts about setting up iTunes using an external drive. A bit of background info. My old computer broke down, so I got a new one from work. I've always kept my music files on my external drive (I have around 170GB of music). I didn't follow the suggestions in the "migrate iTunes library" post because my old computer died on me. However, I've looked at your posts about lay out of the iTunes folders. Before connecting to iTunes on the new computer, I had reorganized my iTunes folder on my E: external drive, and created an iTunes folder which contains an iTunes Media subfolder. The music files are in a Music folder, which is in the iTunes Media folder. I've also put the following files in my iTunes folder: iTunes Library.itl, iTunes Library Extras.itdb, iTunes Library Genius.itdb, iTunes Music Library.xml, as well as sentinel. I then followed the advice you gave bmw99 on 2 Nov 2013 at 9.58 (sorry, can't copy the exact answer).
Just to clarify: I'd like to keep all my music media on the E: external hard drive (the computer hard drive is too small), and I'm aware i might never have my playlists back, and that all the songs in my library might be ticked. However, I don't want my library to be duplicated.
I'm at work at the moment, but will be back home in about 10 hours, so I can be more specific about folders / files names.
I'm glad you picked up my message and greatly appreciate your help.

MacBook can't see my home wireless network after upgrade to OSX 10.8.5

After upgrading to OSX 10.8.5, my MacBook does not detect any wireless nertworks. My iPad and iPhone work fine, my router has been rebooted, WiFi is turned on, and the ethernet connection is how I am writing this message to you via broadband. There are a half dozen wireless networks in range (according to my iPhone) but the MacBook cannot find the router I am sitting next to. Any ideas on how to correct this issue?

It appears an SMC reset was required:
HT5815 I've just done the 10.8.5 update on my MacBook Pro end of 2008, and WiFi don't work after reboot... Impossible to activate it...
Here is your other post: MacBook can't see my home wireless network after upgrade to OSX 10.8.5
If you reply to it and marked it "solved", perhaps with a link to that post (copy and paste it, or just say you performed the SMC reset) it will help others find a solution. Thanks!

Hello, my sister her macbook pro cannot connect to our wireless internet. My imac however can, so the problem has to do with her laptop. We were wondering how we could solve this problem? Thank you very much in advance!

We did that, but it just doesn't seem to be able to connect. So basically we tried to connect to our network and insert the password, but afterwards it does nothing. Weird thing is also that the network symbol (top right of the screen) says that it has been connected, but when I go look at the system preferences --> network, it states that it has not been connected

How to connect my macbook pro to a computer-to-computer network?

how to connect my macbook pro to a computer-to-computer network? My home computer is a Window 8 OS. Thx.

The easiest way, and it may work from scratch, is to share the folders/drives you want access to on your pc, noticing what are the default parameters (eg "workgroup" etc.).
Then, you can connect your mac directly by ethernet, for instance, and, in Finder, go to > Network, you should see the folders/drives. You may be asked to provide user/password.
Don't get confused by regular/crossed ethernet cable, as mac can cross by software, so a regular cable will be ok.
Anyway, either you isd modem has the ability to connect several devices (multiple ethernet sockets, or wifi), or you can buy a router, which isn't expansive.
