Brand new MacBook Pro won't connect to WiFi after one day.

I got my MBP replaced by Apple on Sunday. I used it a bit that night, and let migration assistant transfer everything over from by backup drive overnight. I used it for a few more hours the next day, no problems. I brought my computer over to my friend's room (we're in a dorm building) and tried to connect to her WiFi. Whenever I try to connect to a network, there's an "!" over the WiFi bars in the status bar, and in Network Preferences, under WiFi, it say "No IP Address."
I am having the same issue in my Windows partition as well, which leads me to suspect this is a hardware issue. I am still able to view WiFi networks. I just cannot connect. Any suggestions? Thanks.

Hmmm...yes, there should be, although resetting the modem isn't hard (unless they mean something along the lines of resetting to factory settings). I wonder, tho, if the modem is old enough that something in your new computer is not communicating with it.
Can you connect with an ethernet cable? That might help you figure out if it really is a problem with your modem. You might also check with your internet service provider. I realize not all of them can deal with Macs, but if you rent the modem, they might be able to get you a newer model and if not, they may be able to make a suggestion.

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 won't connect to WiFi after installing a new modem...

WiFi set up fine on the other Mac in the house (MacBook Air) and on my Android phone (using WPS button on modem). I can find the network in the dropdown, but when I enter the password, it says "invalid"—even though it's correct. In the Network portal, I also get an error message saying that there is "no IP address"? Can't set up on iPad either. All used to connect just fine to the old network, just by entering a password. Any thoughts?

Macbook Pro won't connect to WIFI

Help! My new Macbook Pro won't connect to my home's existing WIFI network. The other computers (PCs) are running on it without a problem but when I try to join the network it rejects my password as being incorrect, though it definitely is the right one!

Check to make sure the Caps Lock is off.
What type of wireless security are you using? If it's WEP Mac's don't do WEP anymore and you will need to change it to WPA or WPA2.

Brand new macbook pro 15" when connected to external LCD display in high resolution ,flickers often

Hi,
I have brand new macbook pro 15" with retina display.
I have connected external LCD display (Samsung B2230) using Apple VGA adaptor & thunderbolt port. But LCD display flickers quite oftenly. I read community blogs where many macbook pro users like me are facing similiar issue.
There is no problem with LCD display as it works fine with Lenova laptops.
Can anybody please provide me the solution to this problem.?
Regards,
Sam

My brand new MacBook Pro won't turn on. What's the deal with this?

I got the thing yesterday. Sat down with it last night and everything started up fine. I set up my account and then it was time for updates. Naturally, I said yes to the updates. They downloaded, they installed, and that was the last time my brand new MacBook Pro turned on. I've checked to see that the battery is fully charged. I've tried plugging into other outlets. I've tried removing the battery and the power cord and pressing the power button for 5 seconds. Nothing has worked. When I put my ear up to it while pressing the power button, I can hear it try to start and get about 2-3 seconds in to start up and then a click and nothing. Does anybody have any idea what the heck has happened here?

New Macbook pro won't connect to older external hard drive

My old MacBook suddently died after seven years. It contained a lot of data that I had backed up on an external hard drive using TimeMachine and transferring files to it. When I hooked it up to my new MacBook Pro (released mid-2012 I think), I couldn't seem to connect. Any ideas why?

does it show up in disk utility at all?
Did you have a second NON time machine copy of vital data as should be the case?

Brand new macbook pro won't turn on

I bought the new macbook pro on May 15 2010 from Best Buy. It has up til now been working great. When i tried to wake it from sleep today it would not turn on. It isn't even charging with the power cord in (the little light on the power cord isn't on). I guess I bought a brand new dud. Any suggestions?

wow thanks guys. So I took it back to best buy today and of course the Geeksquad guy comes back to me and says it was working. Apparently the battery drained down to 0. I have no idea how exactly that happened. I always leave it plugged in and it was the last time i used it before it stopped working. i put it to sleep, and when i tried to wake it the next day i got absolutely nothing. I did try other outlets, and was able to function my PC laptop on those same outlets, but for whatever reason my MAC wouldn't even charge (the little light on the power cord didn't light up when it was plugged in). Ugh. Anyway, so all is well now i guess, cause it's working. I still don't understand how it was able to drain itself all the way to 0 while asleep and then refuse to charge no matter what outlet i tried. Geeksquad guy said the adapter was fine. And my outlets worked when i plugged other things into them. Guess i'll leave well enough alone?

Brand New Macbook Pro Won't charge

I recently joined the Mac world, and purchased my first Mac, a Macbook Pro. I have had it less than 3 weeks and the battery won't charge. I have called the support line, several times and they had me take the battery out put it back in press 4 keys and restart worked a couple of times, but I had to do everytime I shut my computer down, not fun at all. Finally they sent me a new battery and that one doesn't charge either. I'm kind of frustrated with the entire process, I was thrilled to be advancing in the technology world but now am very disappointed with the service to help get this issues resolved. So now I have a product I can't use, brand spanking new laptop collecting dust, and the only solution they have for me is to drive 100 miles to an apple certified dealer to have them look at it, only open Mon - Fri. So know I have to take off work, drive way out my way to have someone look at my computer. But the catch is they might charge me even though I purchased the extended 3 year apple warranty. So know I'm back to using my PC. My thrill is gone. All I want is to use my laptop, and experience the Mac way, does anyone have any solutions. So far my experience with mac support is not too thrilling what's the purpose of purchasing the warranty and I recieve no help on their end. HELP?

that doesn't make any sense.... you have a 3 year warranty... they can't charge you... thats the point of the warranty!!
you don't have to drive out to drop your laptop off.... call apple care and they will send you a box in the mail so then you can put your laptop in it and send it back to them so they can repair what they need to repair.... you said that you can't use it anyways so i guess it wouldn't matter that you would be out a laptop for a few weeks....
I wouldn't let them say they cannot do anything for you, thats just ridiculous, you paid good money for your computer as well as a warranty... be persistent.

Can i use a brand new macbook pro without internet connection? I can't get through the setup without specifying internet.

My friend bought on my advice a macbook pro. He has no internet connection at home. Getting started with the macbook pro, we can't skip the internet connection information box.
This may seem a little strange in a www organised world, but he only wants to use the macbook for storing photos and music.
Is there something we overlooked, or is internet connection a must?
Thx

There should be a place to select "Other network options" or some such wording, where you can select "This Mac does not connect to the internet."

Brand new macbook air won't connect to my wi-fi

Was really looking forward to no more Vista but have had to go back to the old laptop to ask this question.
I switched on the Macbook Air, followed the setup and waited for it to detect our wi-fi. I selected it and entered the password but it cannot connect, and doesn't give a reason. I tried several times and even disconnected my old laptop and reconnected to prove I was using the right password.
Our router is a Belkin_N1 and there's no setting on the MacBook to configure it, other than the password. I've obviously done all the usual things like switching off and on again, making sure the right case was selected.
I've been Windows up till now but was expecting the Macbook Air to be as slick as my iphone. Have I made a bad mistake, and how do I get some support for this issue?>

Thanks Xandris. That was one of many steps we tried, and we're still offline
We spent 2 hours on the phone with Apple yesterday and there are still no resolutions. We think they secretly believe our router is faulty or we are putting in the password incorrectly.
Last week we added a Canon printer to the network and after our call with Apple yesterday we gave up on the Macbook and set up our new Samsung TV, which also connected to the Router without problem While on the call I deleted the router from the list in my iphone and reestablished it successfully. The problem must rest with the macbook
Our next steps are to take it to our Apple solutions centre later today. If they can't fix it we can get a new Macbook.
I'd booked out large chunks of my weekend to play with my new toy and get it up to speed with my life, so I'm feeling slightly deflated at the moment

Brand new macbook pro won't recognize headphones?!?!

Howdy y'all
just got this Macbook pro 13" less than a week ago... I was getting ready to record a song, plug in my headphones... the sound continues to play through the internal speakers... this is SO frustrating.
this macbook pro replaced an ol 15" black macbook which had problems with the headphone jack also (red light coming out of the port)
someone please tell me how to fix this. i've tried several of the "fixes" seen on this board, nothing worked. doesn't even show when i pull up system preferences.
Apple, this is seriously unacceptable
what are we paying 1,500$ for?!?!?!?

Have you tested to determine if the headphones are functional?
Since you got the MBP less than a week ago, have Apple check out your problem and fix it or exchange for another new one, or if you are totally dissatisfied, a refund.
Ciao.

My brand new MacBook pro won't shut down, the display screen is on and the pointer moves, but otherwise it's stuck!

I gave the command to shut down, but all that happened was the the dock cleared, leaving nothing but the wallpaper behind along with a moving pointer. I got it yesterday, so it's brand new. What could be the problem?

Hi b,
Hold the power button down for 5-10 seconds and it will shut down. Wait a minute or so before starting up again.

Macbook Pro won't connect to wifi but other computers are working perfectly

Hi,
I have a 2012 MacBook Pro that connects to WiFi no problem anywhere else - except for my parent's house (who I am currently visiting). There are 2 other PCs in the house that connect to the WiFi without a problem, as does my iPhone. When I try to connect, the Network Setup Assistant keeps saying "Connection Timeout" and then when I go into "Assist Me" the error comes up as "The password you entered is invalid." I know that the password is correct, but I can't get passed this step...tried restarting computer and router but no luck.
Help!!

Click the Advanced button in the Network preference pane, then the TCP/IP tab. Type something (anything, as long as it's unique) in the DHCP Client ID text box. Click OK, then Apply. Reopen the TCP/IP tab and click Renew DHCP lease.

Macbook Pro won't connect to wifi while all other macbooks in house will.

I have a MacBook Pro running 10.6.8 and we got wifi at the house this afternoon. It will not connect, if I open network diagnostics the top four lights are green, internet and server are red. There are two other macbooks in the house(at least one also running 10.6.8) and two ipads, all of which connect with no problem. The macbbok in question connects fine at coffee shops and, up until a week ago, fine with the wifi at my last apartment.
We are using Charter and the router is a Motorola SBG941.
Thanks for any advice you can give!
