Macbook pro cannot connect to the Wi-Fi

I am having difficulties connecting to the wi-fi in my apartment. I was able to connect to the internet just yesterday, and it worked perfectly fine. When I try and connect to my wi-fi, there is a check mark next to the router name, however the wi-fi symbol on the top portion of my computer displays an exclamation point, stating that there is no internet connection.
I have tried restarting my computer, restarting my router, and tried running network diagnostics.
The internet is also working perfectly fine for my roommate; my computer is just having difficulties connecting to the internet, which is odd because it worked perfectly fine yesterday.
Any suggestions?

Macbook Pro cannot connect to the internet even when others can

Hi! Please help me. We have an internet WIFI connection in our office but only my MacBook Pro cannot connect even when I entered the correct password. My Iphone and Ipad work just fine. It says "connection timeout" but all other laptops can connect. I tried network diagnostics already and it always say "connection timeout". I dont know what to do anymore.

Yes, and when I open the Network Utility it shows a working IP address, and a 54Mb/s speed from the wireless router. It even shows the shared computers from my roomates. But when I try to access the internet it does not load anything on Safari or Firefox ( or any other internet application for that matter). It is completely unconnected. YET, As soon as I activate the AirPort card on the top right where I have my signal strength, it shows on the Network Utility information that there are 'packages' being sent and received, and I have NO programs open what so ever, I have closed everything except finder and network utility... Does this mean I am being hacked, or have some sort of Trojan or something in my computer? I ran an antivirus that my school provided, called Virex by McAfee, it came out clean except it says it cannot read one file.
I tried repairing my disk, and that did not work either. I did the Ram reset like you suggested, but that also did not work. I doubt it being a hardware error. I am going to try to connect it to an ethernet cable to see if that will work. Then I will let you know what happens with that, but that would still not be a solution since I need it wireless, cause the router is in another part of the house.
Thank you for your help, and I hope we can get this sorted out.

MacBook Pro Cannot Connect to the Internet

My MacBook pro was perfectly active and online, in my linksys router last night before I went to sleep. I left it active as I was downloading some files, they were going awfully slow, but I didnt pay attention and left up. When I woke up today, and tried to use my computer it seemed to be kind of slow and frozen, so I forcefully shut it down and then powered it on. Everything was normal, and my airport card connects to my network, as it is supposed to do. I try to load Safari, Mail and even Firefox, but nothing works. All my other programs seem fine. I started running Virex to see if it detects anything, but I dont know what is happening.
I have made sure that my network is working, since 3 of my roomates use the same internet from the same router, and they all have internet. Even my iPhone has internet. Everything is working except my MacBook pro.
So, I tried going to preferences and getting a renewed IP and DHCP server, like I do when the computer is lagging a little bit, it did not work either. I have reset again, by using normal reset setting on Finder. Still no Internet, I have no clue what do or why it's happening, this has never happened before, and I do not think is anything but my computer software.
I appreciate any help and suggestions. Thank you very much.

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

Select the wi-fi tab in the menu bar then select "Open Network Preferences..." Select the "Advanced" button, then select the network that it is interfering with your MBP, then hit the - button and it will "forget" that network. Hope that fixes your problem, good luck.

My MacBook Pro cannot connect to WiFi

Hi guys.
I have a MacBook Pro 15" which I got about two years ago. I'm using OS Lion 10.7. I didn't had any problems for two years but about a month ago our wifi had a little damage. So we bought another one, the same model. First none of the devices were connected but then our iPads and iPhones did. Then my sisters macbook pro which is the same of mine, got connected. But everytime I try to connect it says "Alert: no internet connection". My Macbook can find the wifi, but it cant connect it. When I open network preferences, It says "Wifi does not have an IP address and cannot connect to the Internet." But my sisters macbook with all same settings with mine can find the IP address! I really need help, Im a student and my homeworks are on websites so I should connect to internet. Hoping for answers .
P.S ( English is not my native language, so sorry for mistakes )
Ozan.

My Macbook Pro cannot connect to my Wifi

Hello,
My Macbook Pro has had trouble connecting to my landlord's internet ever since he added a password to it. I tried my cellphone with the password and it connects to it however my Macbook Pro does not. The password I entered is correct and works because the green lights, light up in network settings and the Wifi signal is at top bar on my Macbook Pro. But, no pages load. The blue loading bar goes almost half way and stops. I downloaded all the updates to see if that would be the fix but no it still doesn't connect. Other places like cafes where their is Wifi I have no problems with. It's just at home. My cell on the otherhand is able to connect. So I dont get whats wrong?

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 Cannot Connect to SMTP

I am running a 2010 MacBook Pro with OS X 10.6.8. I use Mac Mail app to send and receive e-mail. Since Thursday 27th Dec 2012 I have been unable to send e-mail. I get the grey spinning wheel until the following error message appears:
The SMTP connection to server “mail.(mydomain).co.uk” failed.
My outgoing mail server is currently showing as offline. In fact I have 2 e-mail accounts and both are showing as offline. No problem receiving mail. Connection doctor connects fine to incoming mail, but not outgoing.
I have tried the following (plus other things) without any success:
Checked all the details, passwords etc
Changed ports from 25 to 465 and 587
Checked my IP address - it is not blacklisted
Removed and re-added e-mail account
Telnet port 25 - it is not blocked, but appeared to successfully connect (from what I understood from checking www)
Temporarily disabled firewall
Re-installed Mac app
Rebuilt mailbox
Repaired disk permissions
Used the repair disk utility
Deselected SSL and changed various options within "Edit SMTP server list"
Reset the keychain
Tried updating software but it says no update available.
Re-instated an old Accounts.plist (and one other file which I forget, something like com.apple.mail) from time capsule.
I then set up a hotmail account on Mail app but had exactly the same problem, ie cannot connect with SMTP server.
However, I set up my e-mail account on my wife's iPad with the same details and there was no problem at all, e-mail sent just fine as it does from my iPhone. So the issue has to be with my Macbook, right? Can anyone help before I go and spent £1250 on a new Macbook? I'm sure I'm missing something obvious. Thanks in advance for any advice.

Just FYI, I've had the same problem for months now. I have been accessing my hotmail via the web, but decided to try the OS X Mail app. I could get emails into the account with no problem but couldn't send. I read all the blog and support entries and have tried everything they recommended, like changing my computer name to one word, without success. Then last night, it just so happened that my broadband provider had to change out my wireless modem. As soon as he plugged in the new one, some emails that had been in my outbasket for a month went through instantly and all of a sudden my Mail, both incoming and outgoing now work. So I think people need to look at their router settings for the a solution to the problem.

Installed a new harddrive in my macbook pro. cannot connect to hp photosmart all in one printer!!

I, recently, installed a new hard drive on my MacBook Pro Laptop Computer (2007 model).
Now, I cannot print out anything on my HP Photosmart C7180 All-In-One Printer! They don't
seem to be connected, as the printer icon shows up on my computer, and then, immediately, evaporates
into thin air.
How do I connect my HP Printer to my laptop, now that I have a new harddrive installed?

Hello Lady22:
When you received your printer you should have received two insulation disks one is for Windows computers and the other one is for Mac ( Apple Computer) If you have the disks please install Mac disk. Apple computers do search and down load the parcel software so you can do basic printing commands. You need to find the program that is some where in your computer that allows you to hook up Pinters and Devices. Ounce you find this open it up then connect the printer cable to the lap top. The computer program will list HP's printers yuo need to select your printers model number. Then it will down load the drivers for it to run basic commands. Ounce they are download run a test to make sure it is working right. Contact HP's store and asked them to send you a new set of insulation disk. Your old disk may have fine dust film on them. Clean them off pior to inserting them If you use glass cleaner and fine cloth make sure they are dry off before you insert them. If you used them before maybe a speck of dirt blocked out parcel program that caused it not to install correctly . frrw

Brand New MacBook Pro Cannot Connect to Airport Express

Hi all,
Been reading through these pages and I think there are many others with the same problem as me but with no real answer, I thought it wouldn't hurt to ask anyway.
I have an Airport Express which I bought a couple of years ago. It initially worked fine on my old MacBook, I moved house and then it stopped working (flashing amber light syndrome). I got so fed up with it that it has been languishing in the loft ever since.
After a brief stint with a Windows laptop I decided it was time to return to Apple, and I haven't regretted it for a second.....until I got the Airport Express from the loft!
It simply, fundamentally and irrevocably...doesn't work! It's plugged in, amber light flashes but my nice new MacBook Pro just doesn't even recognise it exists. I have tried running the setup utility but at the first screen I am told that no unit is detected, I'm then told to check my Airport card (I assume it means the inbuilt modem which clearly works as I am writing to you guys now!). I can't even progress with the setup after this.
I have tried each of the Airport setup utilities to no avail (lap top cannot "see" AX).
Just as an update, I just connected my AX to my wireless router with an ethernet cable, a new network called 6ad16d appears to be available. Airtunes then works and I can connect to the internet (albeit slowly). I am not happy with this arrangement though as there is no padlock next to the new Apple network so I am worried that it isn't secure and surely I should be able to just plug my AX into the main and my hifi and it should work anyway?....just like it used to!
My apologies for the rambling post and please excuse my lack of computer knowledge. I really hope someone can help!

Fixed! You jut need a girlfriend with a lot of determination....not even sure she knows how she did it. Involved a lot of menus and a lot of swearing.
Surely this should be easier?!

Late 2010 MacBook Pro Cannot Connect to Internet

Hello, First time posting a question here.
I have a late 2010 Macbook Pro 15" i5, 2.4Ghz, currently running 10.6.8. At my apartment the provided wifi has been spotty for several months. In the past I have been able to turn off my airport using the dock at the top of my screen, wait a little while (30 seconds or so) and turn it back on. I would get wifi back and then be able to resume to use the Internet.
Recently, however, I have been having extreme issues with connectivity. I will see full bars on the airport display but my dropbox icon (what I use to test connectivity real quick) will keep indicating that I am not connected to the internet. For the past week I was able to get internet with an ethernet cable plugged into the router, ONLY if my airport was turned off.
Now I cannot even get internet through the ethernet cable.
Here are some things I have been able to eliminate.
Bad computer hardware - My computer instantly connects to the wifi at my family home, on campus and where ever I have ever been. I get reliable, un-interupted internet connectivity.
Bad Wifi signal - All other devices (including the ipad I am writing this on) connect immediately to the wifi with no problems with connectivity.
About my computer:
OS: 10.6.8
CPU: intel i5 2.4 GHz
Memory: 4Gb 1067 MHz DDR3
About my Router:
Ubee DWW365 Wireless Cable Modem
ISP: Charter
I have indeed rebooted my router, but not luck yet.
