Update: I found a web page at MacShadows which lists default login credentials for many routers.

Here’s an easy way to determine the default password for many routers. You might need to know your router’s default password if you forget or don’t have a record of your router’s current password or if you end up resetting the router to its factory defaults. You can visit the Open Sez Me web site to locate your router and determine its default login information. I recently had to use this web site for a client whose router had been setup by a friend a few years ago. My client didn’t have any record of the password. I guessed that the friend hadn’t changed the password from its default. So, I used the Open Sez Me web site to locate the particular model of router and its default login information. Sure enough, it worked on my client’s router.

Firefox and Safari for Mac are the two most popular web browsers for Mac users. At times, both of them can act up and not perform properly. When this happens, here are a couple of basic troubleshooting steps you can take.

In Safari, go to the menu named Safari and select “Empty Cache”. This will remove the local (cached) copy of recently visited web sites. This might be all you need to do to fix your problem. If not, you can continue by going to the Safari menu and selecting ”Reset Safari.” This is a very handy feature that lets you easily remove some of the saved information which can get damaged and cause Safari to misbehave. By default, all of the options are checked in the Reset Safari window. Typically, I recommend that you only select and reset the following since they seem to cause the most problems:

• Remove all webpage preview images
• Remove all website icons

If your Safari problem is not resolved, you can go ahead and select other items to reset. Be aware that removing saved names, passwords and AutoFill data can mean that you’ll be prompted to re-enter this information down the road. Consequently, I try to reset these items last.

Firefox doesn’t have a handy reset feature the same way as Safari. However, you can empty its cache by doing the following. Open Firefox and go to the Firefox menu. Select Preferences, click on Advanced, then click on Network. Click the “Clear Now” button in the Offline Storage section. To do more advanced troubleshooting in Firefox, I recommend checking out this helpful troubleshooting article written by the makers of Firefox.

Did you know that you can take pictures of what’s on your iPhone’s screen? For example, you can take pictures of a text message, a web page or an email configuration screen.

The procedure is simple. Press and hold the Home button while simultaneously pressing and releasing the Sleep/Wake button.

The Home button is located near the bottom of the front face of the iPhone. This is the button that you typically press to exit an application and return to your Home screen.

The Sleep/Wake button is the button on the top edge of the iPhone which you typically use to put the iPhone to sleep.

Be aware that if you were to press and hold both the Home and Sleep/Wake buttons continuously for 10 seconds, this will reset your iPhone. Resetting an iPhone isn’t necessary very often, but if your iPhone locks up and becomes completely unresponsive then resetting is often helpful. Resetting the iPhone essentially just forces the iPhone to turn itself off and then start up again. It does not remove any of the data or applications on the iPhone.

The ability to take a screen snapshot was added in version 2.0 of the iPhone software, released in mid-2008. If you happen to have an original iPhone and have never updated its software then you don’t have the ability to take a screen snapshot with your iPhone.
