Can I schedule access to my network for devices in my household?

It should be there...Goto Settings - Wireless & Network - Tethering & Portable Hotspots .
First though activate the Wifi then the Tethering option as described above.
Switch on any device you want to tether to and look for your device name (or you can setup a password from same list) and continue to tether.
Be advised though, some Network Operators will tell you that it's unable to tether or warn you against it. But I've had this a few times and I still tether what I like.
also be advised that if you on capped data plan, keep an eye on your data limits.
Good luck.

What most likely happened is when you factory reset the device, the wireless setup that you use to connect to the Internet was reset as well. You need to go into the wireless setup area and look for networks to connect to. The one that you use regularly (assuming you are where you use the device), should be among those listed. You then tell the device to connect to the network. This is where the device will ask you for the network password if it is a secure network (and most are). Once you input the password, then the network router will assign an IP address to the device and connect it to the network. After that you can access the Internet normally. If you don't know or forgot the network password, someone in the household (or business) should be able to provide it so long as you are authorized to connect.

A network printer can have many more connections. Most people have a wireless router that allow the whole household to use. The printer must have a unique IP address that was assigned by the router. From there the computer simply pints to that resource (IP via network cable) once it has been installed on each computer or device. Think of like a office setup.
Windows also allows for attached printers to be shared if the printer is not networked directly to the router (USB connected to PC), but the network setup still applies to the computers.

Had the same problem on my Dell Latitude running WinXP SP2, installing a HP6380.

I noticed the installer was trying to access the other network printers I had setup (the status of these printers turned into "unable to connect" in Control Panel.) These printers are on the company's network and were not accessible from the home network I was on at the moment of installation.

I then started a VPN connection to the company's network, so that the printers were all accessible. The "add device" part of the insallation then went through and the printer was setup successfully.

If your getting that message on your computer that means the IP address that your computer acquied from your serverrouter has a duplicate in the network. The very first thing that you need to check is whethere your computer has a an IP address that is manually assigned to it, to check this just go to Network Connections under Control Panel(assuming your computer runs on Windows XP). Right click on the Wireless Connection icon and go to properties, under Local Area Network Properties you will find several check marks under This device uses the following; Client for Microsoft, File and Printer Sharing, QoS Packet Scheduler etc... Look for and highlight Internet Protocol(TCP/IP) and click Properties, under the TCP/IP Properties you have 2 option for both IP and DNS server. Make sure both is set to obtain. If your still getting the same message Right click on Wireless Connection and choose repair so tha your router/server will provide a new unique IP address, wel that will usually resolve the IP address conflict on your computer.
