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)

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!

All,

I had the same problem most of you have and I fixed it this morning. It's not a problem with the Mac Book or Lion it's a security issue with your wireless router. Most routers have a limit of how many computers/devices can connect to them (I have 2 Macs, an iPad, PS3, XBOX360, 2 smart phones). My new Mac Book Pro had many of the same symptoms and was competing with my other devices to connect. I found this website a while ago when I was setting up my "secure network" and went back to it today and it hit me! Just increase the maximum # of devices that are allowed to connect to my router.

http://technicallyeasy.net/2007/09/securing-linksys-wrt54g-wireless-router/

(this works for almost all routers not just the wireless G) Follow the directions through #4 and that should do it.

I hope this helps.

Cheers!

Bass

Simonsachs fix WORKED. This is coming from a Mac 10.5.8 user who couldn't connect to their home wifi AT ALL while iPhones and an XBox could for almost 6 months. Thank you so much!!! What a simple fix! 😀

YESS BDAqua. WHAT YOU SAID WORKED FOR ME PERFECTLY. Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed. Before I went through network diagnostics and all of that stuff in system preferences, and then I tried the "Join Other Network" method, and now it works like a dream. Thank you BDAqua.

I have a similar issue with Safari on my Mac Pro 2.93 Ghz, running Snow Leopard 10.6.8.

When I reboot the computer, Safari doesn't work at all until about two or three hours later. So I have to use another browser. I prefer Safari and like Safari and would like to continue using Safari ....

I'm using Safari 5.1.2. Can't go back to any of the older versions, unless I downgrade my Operating System, which I can't do, for obvious reasons ....

I've tried resetting Safari, trashing the plist. Trashing Safari and reinstalling.

As long as I do not reboot, I can quit Safari and restart Safari and it works just fine. But everytime I reboot the computer, Safari will not work until two or three hours later ...

This problem has been going on for many months now ... Any suggestions? Has anyone else had this issue and found a solution ... ???

Just to let you know, your tip of 28 August 2011 solved the problem for me (MacBook Pro with Lion). Would suggest everyone to check that out, thanks BDAqua.
