Macbook pro cannot connect to internet

Hi, My Macbook pro 13" will not connect to the internet via wifi or ethernet. I have tried about everything I can think of. I reset the modem, tried another network other than mine. Compared the settings between my Imac that will connect and the macbook that will not. The only difference I can come up with is the macbook has a different ip address then the imac when connected to the same network. Any ideas? Thanks.

My macbook pro cannot connect to internet via wifi

I have a Macbook Pro 2010 OS X 10.8.3. I cannot connect to internet via wifi (Air por). My Macbook Pro does not recognize my network and when I select it from the list of network it asks for my network password. when I type in my password a dialog box gives me timeout error. Please could anyone help me. I am using ethernet for my connection at the moment. Do I need to reset my macbookpro? if yes, what will happen to my applications and operating system (mountain lion)?

When you use the Airport utility what happens?
What is in the System Preferences control panel for Network settings?

Wi-Fi Setup Considerations
Things to consider before you begin
Start with a plan for the physical layout. Depending on whether you have an existing Wi-Fi network, or if you are using your AirPort Express as a standalone Wi-Fi device, there are several options available for you to choose from.
When using Ethernet, Cat6 cable is recommended.
The layout you choose should take into account environmental factors such as physical access, location, range, radio frequency interference, etc.
You will need to consider what AirPort Utility settings to adopt.
You will need to know whether you are using an AirPort Express (802.11b/g) or an AirPort Express (802.11a/b/g/n).
If you will be using more than one Wi-Fi base station, it may be helpful to read the article Extending the range of your wireless network by adding additional Wi-Fi base stations.

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.

Macbook Pro cannot connect to Internet via Ethernet / Cosmetic Issues

My Wireless Router died last night, so I connected my PC Desktop directly to the Modem. It worked like a charm.
I then decided to connect my MacBook Pro (2.4GHZ, OS X 10.5.3) to the Modem and...it didn't work. I tried going into the network settings (turning off the AirPort Card, moving the Ethernet to the top of the list, etc.) and I still could not get it to work.
Aside from taking it in, is there anything that I can do to try to remedy the situation, maybe a setting that I've missed? Also, there is a tiny ding on front of the bottom case. Can I get it fixed if I have the "Accidental Insurance?"

Was the MBP working when you had the router?
Also, did you power cycle the modem when you switched machines? Most cable modems remember the ethernet MAC address of the computer that was last connected to it, and will not permit another machine to connect until the unit is fully power cycled (turned off and back on). This is to enforce network provider policies of one computer at a time per account. (Most ISPs want extra money for extra machines.) The reason you can use multiple machines with a router is because the router performs some special functions to make multiple machines appear as a single machine to the outside world.

New MacBook Pro cannot connect to internet

I've helped setup 2 MBP this week. Each of them could not connect to the wireless internet in my office using DHCP. In both cases I had to make a network setting of DHCP with manual address (I used 192.168.1.150 since my network is 192.168.1.x) and I was then able to see the internet. After an update I could change the network setting to Auto and the computer could connect just fine.
Anyone else have this problem?

Choice is fine. Just a shame you cannot get DHCP to work out of the box. But it is odd they do not work with both Linksys and Airport Extreme.
I am one of those without the connection problems, except with D-Link routers at work -- we have two as (like you) we have two networks. One network uses 192.x.x.254 as router and the other 192.x.x.253 and the Mac defaults to 254 so we have to lie to it and, like you, enter settings manually. So it connects to the one, but not the other, using DHCP.
Do the new computers have the latest Airport Utility (1.2.1) and Airport Disk Utility (5.3.1) installed. Was that the update you mentioned in the original post?

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

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.

This can be caused by a number of issues.
Was everything working and then suddenly stopped??
Or is this a new clean setup and has never worked.
Do you have a cable modem which is not a router and the TC setup in bridge? That will cause it. The TC must be in router mode, ie dhcp and nat.
Check the IP the MBP gets including dns and gateway..
Then check the ipad/iphone.. post what IP dns and gateway (router in applespeak) they get.

Macbook pro wont connect to internet using cable, but connects using wifi fine

My macbook pro wont connect to the internet using a cable, but connects using wifi fine. I use wifi at home but sometimes need to use my laptop at work and connect using a cable but it says i'm not connected to the internet?

Can you open a terminal and invoke the following commands:
ping -c 10 localhost
and
ping -c 10 google.com

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.

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.

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?!

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.
