I have a single desktop iMac OS 10.6.5. Having just acquired an iPad which I want to run on WiFi, I enabled same by enabling the desktop access WiFi without purchasing a new router... I am connected by DSL. In Utilities, in Network, I select AirPort and now my computer as well as my iPad will run on WiFi so I don't have to pay 3G fees. Problem is after some minutes my computer drops AirPort and re-selects Ethernet. My iPad shows that I am still connected, fooling me, but the computer Network clearly shows the real case.

The computer should be connected to the Modem via Ethernet cable and NOT Airport.

OS X will redirect the Internet connection by bridging from ethernet to wireless so that the iPad can connect.

If you ask your phone company nicely, they will supply you with a wireless router/modem, for free!

That won't work

That won't work. You either have to use airport for supplying an Internet connection to your iMac or iPad, it can't be both.

So, if you want to keep being a cheapskate, you'll have to use ethernet for the iMac and airport for the iPad. Otherwise you'll have to crack open the wallet and get yourself a wireless router.

but the iMac can "Share" its internet connection by taking in ethernet and putting out wireless.

System Preferences > Sharing > check the Internet Sharing box and turn on Airport as instructed.

It's been able to do that for a number of years.

Allow me to rephrase then

Allow me to rephrase then: You'd be well advised to use airport for one or the other given the half-duplex nature of wireless.

I was making a more absolute statement for the sake of clarity... Like not having to dredge up terms such as half-duplex.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
