Q: Mountain Lion: Problem with Internet (Wifi and ethernet)

Good morning,

I'm sorry for bad english, my primary language is Portuguese.

I looked at community before asking here, I have found the same problem (here and at others forums), but the problem remains after trying all that I found...

 

The problem: My internet down (a lot of times) and I can't access nothing (at my work and my home). It remains for seconds.

At my work, I access the Internet under a proxy and a lot of Mac users (previous versions) and PC connects with success... I'm the only one with trouble.

At my home I have a Time Capsule (2TB model - with the guest connection turned off) as main router, connected at a Cable modem and configured as default... PS: I can access the Time Capsule data with Internet problems...

I've tried many thing, between change the MTU value, reinstalling the OS (a lot of times), creating a new location, changing the TC channel, changing browsers and others...

I took the equipment in assistance few months ago, they did the complete test and they found nothing, I'm thinking on getting back there...

I do not know what to do...

 

Details of MBP:

Macbook Pro 9,2 (middle 2012)

OS X 10.8.4

All programs (and system) are up to date.

 

My home network:

  • Cable modem

  • Time Capsule

  • Apple TV3

  • Macbook Pro 2012

  • Notebook Windows 7

  • Samsung Galaxy S3

  • Iphone 4S

  • PS3

  • Nintendo Wii

 

Anyone with any ideas? I appreciate all of that!

 

Thanks all!

 

Regards,

Allan Cristian Barros Silva

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.

 

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
   
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

 

Test while in safe mode. Same problem?

 

After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
