Internet (and Mac) running slow?

Your Mac uses the internet more and more.
Not just when you are actively online, but in the background when you’re unaware of it too.
So if your internet is slow, your whole mac can be running slow too!
To remedy this try changing your DNS settings to Google’s Public DNS - it’s Free and powerful!
It sounds “techy” but it’s fairly easy to do.
Here’s how:

1. From the Apple menu, click System Preferences, then click the “Network” icon.
2. If the lock icon in the lower left-hand corner of the window is locked, click the lock icon to make changes, and when prompted to authenticate, enter your Mac’s login or administrator password.
3. Select the connection type (in the left sidebar) for which you want to setup Google Public DNS.
For example:
• To change the settings for an Ethernet connection, select Built-In Ethernet, and click the Advanced button on the right.
• To change the settings for a wireless connection, select Wi-Fi or Airport, and click the Advanced button on the right.
4. Inside the Advance window click the DNS tab.
5. On the lower right click the “+” button to replace any listed addresses with,
or add, the Google Public DNS info, if none are listed.
• You’ll have to click the “+” button for each address, there are two (see in bold, right down there)
The Google Public DNS address are:

8.8.8.8 and 8.8.4.4.


It should look like this when you’ve done it correctly:



6. If that’s what you see then click the “OK” button and on the next page the “Apply” button.

Lastly quite System Preferences, and restart your web browser (i.e.. Safari, Chrome, Firefox).
You should be able to notice an increase in your surf speed and hopefully your whole Mac.

If not drop me an email.

Detailed Wifi info from the menu bar

If you want very detailed wireless connectivity data from anywhere within Mac OS X it’s simple.
Simply hold down the Option key and then click on the WiFi menu icon.

Option-clicking will display a sub menu under your active wifi connection that shows:
- What wireless band you are using (PHY Mode)
- The routers SSID (BSSID)
- What channel the wireless router is using
- Which encryption method (Security)
- The Received Signal strength Indicator (RSSI) (the stronger the signal, the closer to 0, so -20 Good -90 Bad)
- The transmit rate
- MCS index (an über geeky stat that lets you calculate the available data rate of your wireless hardware).




You can also mouse-over other SSID’s to see a slightly more condensed version of this information. All of this can be helpful for avoiding potential channel conflicts, or when troubleshooting wireless problems.

And yes, I called it the WiFi menu rather than AirPort, since Lion is moving away from the AirPort references, at least in regard to the menubar.
