MacBook won't connect to the internet!!!

I recently switch wireless service at home to At&t.

Since, my computer "connects" to my network, accepts my password, and shows full signal, but when I open Safari, or any other app that requires internet, I just get the "failed to open page because you are not connected to the internet" page.

My roommates connect to use our wireless network with their PC's just fine, and my Mac connects to other wireless service at school and work and works just fine.

I have been on the phone with At&t many times trying to troubleshoot and fix the problem. No success.

Apple charged me $49 to talk to them, with no success.

I HAVE ALREADY TRIED RESTARTING both my Mac and my router, I have reset the router, I have restored original settings in both Safari and my router, I have tried removing the security from our network in order to connect without a password, I have tried re-configuring the router to work with Macs....all no success.

I am very frustrated with the situation as I, like most people, require internet access for both school and work.

Any help, tips, or advice on the situation would be grateful.

Thank you.

MacBook, Mac OS X (10.5.8)

Wow. Same problem. Like often happens when a Mac quirk shows up I just wasted hours of my life and finally got it to work. I'll share the steps I took. First it worked two days ago at the same coffee shop, the only thing that had changed was the password, however no matter how many times I entered the password in the different forms. Nothing. All I got was a not connected... due to the "self assigned IP address" message. I attempted the tricks that people posted here: 1) Turned off and back on the wi fi ... nothing 2) restarted the computer... nothing 3)I went into System Preferences > under TCP/IP I changed the Configure IPv4 to "Using DHCP Manually" and used an IP address close to the one from my other mac which was connected just fine... almost nothing... the green light went on and it said connected under wi fi in the left panel of the preferences... but no actual connection 4) I changed the Manual IP address to Match my working Connected Mac... almost nothing... the green light again went on and it said connected under "wi fi" in the left panel of the preferences... but no actual connection 5) I deleted "Wi Fi" from the left panel and recreated it using the + and - buttons on the bottom of the left pane and hit renew DHCP address, but it recreated the same 162... IP as before and still not working 6) I changed the from a 162... to a 192... nothing 2) I hit Renew DHCP Lease... nothing same IP.


Then...


Here's what finally worked: Again in System Preferences>Network> I turned Wi-Fi off, Went to Advanced>TCP/IP>Configure IPv4 and changed it to off, hit "OK", Highlighted Wi-Fi in the left column, hit the - sign on the bottom left, deleting it, then hit the + and created it. I got a message saying there is no assigned IP address so I went back into >advanced>TCP/IP and turned on Using DHCP, Hit "Renew DHCP Lease" and it finally created a brand new IP address 10..... and if finally F'n worked.


Jeez Apple get it together. This is a ridiculous problem.


I hope my struggles actually help someone

I just purchased a brand new MacBook Pro today and spent my first four hours with it struggling to connect to wifi. After trying every solution I could find, this one finally worked. The solution I found (https://community.bt.com/t5/Connected-Devices-Other/BT-INFINITY-wifi-loss-on-Mac Book-Air-ready-to-quit/m-p/1160960#M7876…) noted that Macs often run in to trouble connecting to wifi when there are identical names assigned to 2.4ghz and 5.0ghz frequency bands.


To fix this problem: access your wireless gateway (For Xfinity users: go to 10.0.0.1 by typing it into the browser of a connected device, enter username: admin pwd: password <-defaults for all xfinity customers) and modify the SSID for the 2.4ghz frequency (e.g., add an 's' to the end of the network name). Then, restart your computer and voila, you should be able to connect. (I still can't access the original network name—the 5ghz frequency—however, I'm able to access the newly named 2.4ghz variation of the network, and it works perfectly).


Hope this saves someone else the headache!

Check your wifi and router are working correctly. Check other devices are working on your network. If they are normal then time to check your network settings are correct. They can be altered without notifying you and affect your connection. This can be because of a DNS issue on your Mac or, if you use a VPN, the network settings can be affected by the software. VPN software on your computer can alter these settings so ensure it is closed and not running. A VPN would normally reset your primary DNS address to one of their own when connected and should reset your settings to your normal DNS when closed. Sometimes this might not happen.


It's a good idea to restart your router and your Mac initially. Ensure your network is being picked up by the affected computer / device. Check your Network settings.


Go to System Preferences > Network.

Select WiFi from the list on the left. Check that the setting for Wifi connection is active. You should see Status showing "connected" and the name of your network and your IP address. Under that is your network name.

If it is active then click on Advanced. You'll see a drop over window showing your network settings.

Click on DNS. Check that you have a DNS address there (example: 208.67.222.222 )

If your DNS address is missing you can manually enter it here, or enter an open DNS address. Click OK and Apply.

Click on TCP/IP. Ensure that Configure IPv4 is set to USING DCHP. You can also click on Renew DCHP Lease.

In Hardware ensure MAC address is set to configure Automatically. Apply your changes.


Hope this helps.

I was wondering if you could help me out- yesterday I discovered that my macbook pro would connect to the internet for about 2 mins via wifi from my home network and then simply stop working. I've tried restarting my router, restarting my mac etc and when I went to delete the airport and add it again, i discovered it's not even on the list. All i have in the left panel is wifi (which is green and says connected) ethernet, firewire, snf bluetooth PAN. I would really appreciate any help. At first I thought it was a problem with my wifi but other pc's in the house work perfectly fine. I even tried to connect my mac via the ethernet and same thing- connects for a while and then stops.
