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: and

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.

Check Wireless Signal Strength using 10.7 Lion

Found this on
Here's the link:

Wi-Fi Diagnostics is an incredibly useful utility to troubleshoot and optimize any wireless networkand the signal strength of computers that are connecting to it. This utility comes bundled in Mac OS X Lion and works with all wireless routers and not only the Apple branded ones, meaning you can improve the performance of just about any wifi network by using it and making some adjustments along the way. It’s easy to use and we’ll walk you through the process of getting the best wireless signal using the app, but first we have to uncover the tool itself.
The Wi-Fi Diagnostics app is buried within
Mac OS X 10.7, here’s how to access it:
  • From the OS X desktop, hit Command+Shift+G and enter the following path:
  • /System/Library/CoreServices/
  • Sort alphabetically and find “Wi-Fi Diagnostics”, if you plan to use the app even somewhat frequently it’s recommended to drag Wi-Fi Diagnostics into Launchpad for easy access
With Wi-Fi Diagnostics now in the easier to access Launchpad… wpen Wi-Fi and check the radiobox next to “Monitor wireless performance” then click on the “Continue” button.

Now is when the fun begins. The chart you see is a live wireless signal strength and noise meter,you want the yellow signal strength bar to be as high as possible. Pay attention to the green line of noise as well, you want that to be as low as possible in relation to the yellow line of signal strength.

If the signal strength is high and noise is low, you’re already good and you don’t need to change much. For most of us, signal will be lower than we want it to be, depending on where the wireless router is stored in relation to our computer gear.
Here are some tips to try out and to improve signal strength, keep an eye on the signal as you make adjustments:
  • Tweak the physical antennas on the wireless router and aim them in different directions
  • Move the wireless router away from walls, fireplaces, etc – even just a foot or two of space can make a big difference
  • Move the wifi router away from TV’s, microwaves, refrigerators, and other electronics that may interfere with signal
  • Relocate the Mac in relation to the router, this is obviously easiest with a MacBook Air or Pro
Once you have arrived at a reasonable compromise to how your hardware is physically configured and signal strength, enjoy your newly optmized wifi network.

Some important things to remember here: not all internet connections are capable of transferring data at optimum wireless speeds, so you may not notice much of a difference in internet connectivity speed if any at all with these adjustments. This basically means that a weaker wireless signal may be more than adequate to transfer data at your ISP’s maximum bandwidth. Regardless, you’ll want the noise level to be as low as possible, since large amounts of wifi network noise can result in lost packets, reduced speeds, quirky behavior, random wireless connection dropping, and a variety of other problems.
