Wi-Fi Networks: One SSID for multiple access points

To setup a Multi-AP Roaming Network give all APs the same network name (SSID), the same security type (WPA2-PSK recommended), and the same wireless security passphrase. Clients usually assume that these settings will be the same across all APs with the same SSID.

Channel is one key setting you do want to vary from AP to AP in a roaming (multiple AP) 802.11 network.  You don't want transmissions to/from one AP to compete for bandwidth with transmissions to/from the other AP.

If you're only using 2.4GHz-only devices with single-band-at-a-time APs, be careful of your channel selection, as they can overlap.. Channels 1, 6, and 11 don't overlap at all, so those are good choices to pick manually. You could use a Wi-Fi network scanner like NetStumbler or iStumbler to see which channels are in use where you are.

Automatically Change Your Default Printer Based on Your Location

Windows 7 & 8 can automatically change your default printer based on which network you’re connected to.

The normal use case, of course, is to switch printers depending on whether you are at home or at work, but this feature is especially useful if you use one of the many print-to-PDF solutions—you can continue to print things even while you aren’t connected to any network.

Go to the Devices and Printers panel, and then just click on one of the printers, which will enable more buttons on the toolbar. Now you can select the “Manage default printers” button.

In here you can change the radio button to “Change my default printer when I change networks”.

And now you can select a network in the first drop-down, and then select the printer you want to assign to that network in the drop-down box.

You can also select the “No network” item in the drop-down box for anytime you aren’t connected—this is good to assign a PDF printer as default when you're offline.


Note: this does not work for Home edition of Windows 7, and only applies to laptop PCs!

Transferring your iPhone or iPad to a new Mac

1. Plug the iOS device into the PC you normally sync with. Load up iTunes, wait for it to be recognised in the bar on the left of the window, right-click and select Backup. Make sure you also Transfer Purchases to keep any apps or media you’ve bought directly on the device itself. 
2. Your backup now needs to be moved to the Mac, along with your music. Using a local network or external hard disk, copy everything in your iTunes folder to your Mac. For apps and other settings, locate your backup and copy the whole folder across. The precise source and destination folder paths are:
    Windows 7 or 8
     c:\users\username\appdata\roaming\applecomputer\mobilesync\backup
    OS X
    /library/application support/mobilesync/backup
3. Without connecting your device to the destination Mac just yet, fire up iTunes on it, go to Edit | Preferences | Devices and tick the box to Prevent iPods, iPhones and iPads from syncing automatically. Only then should you plug in the device, and authorise it when iTunes makes that request.
4. Right-click on your device in the left menu and select Transfer Purchases. Then finally right-click and select “Restore from Backup”. Provided you put all your files in the right place earlier, the sync should run and your files should remain intact. If there are any problems, you still have the backup on your old computer.
