Mac Internet Issue

Post by Admin on Thu Nov 14, 2013 12:36 am

Hi Everybody,
I am recently getting a problem with Wifi. I am using Macbook Pro 13 mid 2010, upgraded from Mac os x lion with wifi patch update. It was working fine, but suddenly my internet stops working. Here is some solutions I already tried:
1. I already tried reseting safari
2. Prefrences file deleted from Library
3. Router has been factory restored, still problem persists.

And one more thing, I am successfuly able to connect the router, can even ping it, but If I try to surf with any browser or even ping any website, nothing works!

Please help me!
MacBook Pro 13, Mac OS X (10.6.6), 4GB Ram 500GB HDD & Win 7 Pro

Try the following:
Open network preferences.
Select your WiFi card on the left.
Click "Advanced"
Click "Proxies" tab.
Enable "Automatic Proxy Configuration"
Close Network Preferences
Quit Safari.
Reboot your Mac and try again.

Why won't my MacBook Pro connect to the internet?
Why does my MacBook Pro not always connect to the internet via WiFi even when my iMac, which sits on the same desk as the notebook, does? The MacBook Pro connects to my home network, but it is unable to access the internet!
Oh thank god for normal people..no help from Apple but I've found some fixes that may work (worked for me now but not holding my breath that they will last!!!
Do this:
Go to Library>Preferences>System Preferences

Delete com.apple.alf.plist

This should work, I also went >System Configuration

And I also deleted these but not sure if necessary:
com.apple.airport.preferences.plist and


System preference>Security>Firewall
Select “set access for specific service and applications”
Click “+”
Press “command+shift+g”
Type /usr/sbin
Click “go”
Select configd
Click add

Also may add mDNSResponder, racoon, DNSResponder

i have a very good solution....my problem was that my web proxy was on. To turn it of, go to network preferences, advanced, then you see a tab in the pop out box saying "Proxies" click there. Now, if the button " Web Proxy (http) has is ticked on in the side, click it to unclick it, if it is not chosen then there has to be another problem..... but this ways what had happened to me!

Browser Network Settings
Internet Explorer:
Tools > Internet Options > Connections Tab > LAN Settings button

Tools > Options > Network tab > Settings button
Preferences > Network tab > Settings button

Preferences > Advanced > Proxies: Change Settings button
