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.

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 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

I am in an internet cafe and my macbook pro can't find the wireless network available here. I have used this network before. I have restarted my machine several times too. help please

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 doesn't connect to a wpa network.

My MacBook Pro won't connect to the internet when I set my router to have wpa security a posed to wpa2, which was what it was when it was set up.
I Want to set it to wpa because the sony psp won't connect to a wpa2 secured network so It would be great if I could change it so all of my devices could connect with out trouble.
Thanks,

Hi JPait996,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro connects to your Wi-Fi network when it's setup as WPA2 but there is an issue connecting to a WPA network. What happens when your MacBook Pro tries to join the network and does it get a valid IP address? The article below provides lots of great tips that should help you resolve the Wi-Fi connection issue.

Macbook Pro won't connect to wireless printer anymore suddenly

Suddenly my Macbook Pro won't connect to my HP Photosmart B210e Printer. I have tried adding it via IP address, it worked but I can't print anything. It says the printer is busy and idle? I updated the software and drivers. All other computers and devices in my home connect just fine. It is connected to our wireless router as is my laptop.
I have searched online and done all the solutions I could find and nothing is working. VERY frustrated as I have to log onto my Dell to print anything.
Thanks in advance for any help!

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!

MacBook Pro can't connect to wireless internet

I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address. I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room. This would work!
So my question is...
My roommate brought up the possiblity that this problem is with some sort of chip in my computer that helps me connect wirelessly to the internet and that it has gone bad and needs to be replaced. It this so? or is there something else I need to be doing? (and I have been trying lots of thing) This is vital to me getting my work done because we are in the middle of the semester and I need my wireless!!
Please help!
Thanks!

thats... odd
thats a real world IP address. So that means you dont have an actual router doing NAT.
It's also very unsecure. I HIGHLY advise tweaking your home network very soon. Without alot more info theres not much that I can really advise though.
You said your roommate can get on the wireless fine - what IP address does he/she get?
Also, i think you said if you plug in with a physical wire it works as well - what IP address there?
Do you know if you have an actual router? Or is this simply a cable or dsl modem?

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.

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 won't connect to wireless abroad whereas other devices do.

Hello,
I've gone from the UK to Australia to visit family taking my MacBook Pro with me. The only thing is (although working perfectly fine back home) it doesn't seem to do very well with the Internet here. It "connects" to the wireless device (located directly under the desk) but firefox, safari, skype and the like do not connect to the web. My iPhone and iPad, however, work just fine as does my dad's MacBook Pro.
What's up?

Windows XP on MacBook Pro - Can't connect to wireless after bootcamp, why?

1)I just bought MacBook Pro, just did a boot camp with windows xp. With Windows xp installed, it can't detect wireless network. What went wrong?
2)When setting the boot camp, do i need to have the boot camp driver? Why?
3)Can Windows xp on Macbook pro use the same built-in modem, or do i need to get a modem/ adaptor for windows on mac, so the wireless (on window xp on mac) would be able to work.

Did you install Apple's bootcamp drivers after you installed Windows? You should be able to accomplish that by booting into Windows and then inserting the installation disc that came with your MacBook Pro. Without Apple's drivers, Windows may not know how to use the wireless circuitry on your Mac.
3) Can Windows xp on Macbook pro use the same built-in modem, or do i need to get a modem/ adaptor for windows on mac, so the wireless (on window xp on mac) would be able to work.
With the proper drivers Windows should be able to use the wireless equipment that came with your Mac.

Macbook pro just stopped connecting to wireless internet.

I have tried restarting it and deleting the old usernames and paswords, but nothing works. I thought it might be an internet problem but i am having the same problem at home and school.
Can anyone help me?

My macbook stopped connecting to wireless internet. Ive tried everything. HELP!
Open System Preferences then select the Network tab.
Cick Assist me... then click Diagnostics
If any of the buttons on the left are red click Continue.
That should help narrow down whether it's Wi-Fi or your settings or your ISP.

Brand new Macbook Pro won't connect to wireless internet

Hi all, I'm relatively new to the whole mac thing, but I have a problem. I got a macbook pro for college last week, and have been struggling to connect to the internet ever since. I notice other's are having issues too.
So here's what's going on:
When I set my pro to using DHCP, I get no IP address, or sometimes get the self assigned address 169.etc. Yet when I put in a static address, subnet mask and router info I've found for my network, It says connected but when i click on safari no internet. I've run diagnostic in safari and all the lights go green (under manual ip etc) except internet and server (which are yellow). What's going on here? It can't be the airport card, because my pro connects seamlessly to my college's wifi, my ethernet cable and rogers internet stick. So is it my modem/router combo (using a siemens SE567), or is it because I'm running 10.6.4?
Please help, I have to use the internet for uploading videos and other heavy internet usages that my internet stick can't do (unless I want a $100 bill each month), and being tethered to my ethernet is kind of a bother.
*I should also note I have a pc laptop that runs fine off the network (siemens se567), though setting it up also gave me issues.*
Thanks

I'd suggest you repost over in MacBook Pro forum, and in Using OS X Networking.
There are Apple technotes on troubleshooting networking and setup.

Macbook Pro is not recognizing remembered wireless networks and does not sign on to them automatically anymore.

When trying to connect to my home wireless network, my computer doesn't recognize my network, or any network as being accessed before. It doesn't remember any networks. I even went into the advanced settings and made sure to check the box that makes it remember networks, and it still doesn't remember them. I am able to connect to my home network manually, but it will not automatically connect when I open the lid after it being closed, or when I turn off the wifi and turn it back on. What should I do?

Thank you for your suggestion, and I have, (I actually tought that may have been the problem initially) unfortunately it was not successful. But I did go onto the Keychain Access and fixed the passwords in those and then deleted and reissued my prefered networks and it happened to work out just fine.
Thank you again, clintonfrombirmingham!
