For Each Profile


Edit Profile to Change Network Settings

On the Wii U, you may configure 1 to 6 user profiles. Individual network settings are stored in each profile. Only the selected profile is used to connect to the network. For each profile, you may configure the following settings:

Item Description Saved Information
Status This setting affects only the result that returns when nn::ac::IsReadyToConnect is used. This setting does not affect the ability to connect to a network. Even if a profile is disabled, you may still connect. Valid
Invalid (default)
Edit Config Change the profile settings. For information about the profile settings that you may configure, see Edit Config below.
Clear Config Clears all profile settings, except Status. This sets the Connection Mode to Unestablished, and then you cannot connect to your network.
Connection Test Perform a connection test using the current settings. For more information, see Connection Test below.

Edit Config

On the Edit Config page, you may set and change the settings for individual profiles. In the initial state, connection settings are not set. Items that are displayed vary by setting. The tables below describe the settings available for wireless and wired connections.

Connection Mode Select how to connect.
NOTE:
After you use the Clear Config option, the Connection Mode is set to Unestablished. You may not select it.

This option is available only when the Wireless Connection Mode is selected.


Wireless Access Point Settings

Item Description Saved Information
Config Method Choose how you want to set up the AP. Manual (default)
WPS (Wi-Fi Protected Setup)
Scan Searches the surrounding area for APs, and then displays a list of the APs and their SSIDs and privacy modes from which you may choose. When you select an AP, you may verify the SSID and privacy mode, and provide the privacy key, if required.
NOTE:
This option is available only when you select Manual Config Method.
Config Configure the SSID, privacy mode, and privacy key, if required, for the AP.


Configure Wireless Access Point

SSID

Enter the Service Set Identifier (SSID) for the wireless LAN (WLAN). This is a string that is up to 32-characters long, which differentiates one WLAN from another. Each AP and device on a WLAN must use the same SSID so that they may communicate with each other. Your local network administrator may provide the information required to configure your Wii U to connect to the WLAN.


Configure SSID or Privacy Key for Wireless Access Point

Privacy Mode

Privacy Mode Security Key
None (default)
WEP
WEP(RC4 40Bit)
WEP(RC4 104Bit)
You may set up four 5-character or four 13-character security keys, depending on the version of WEP that your WLAN uses. Use an index to specify the key to use. Each security key is set up by changing the index to use.
NOTE:
WEP technology is obsolete and no longer recommended for use on wireless networks.

IP Address Obtain Mode

IP Address Obtain Mode Description
DHCP When you select DHCP, the IP address, subnet mask, and default gateway are obtained automatically. You must enter IP addresses for the DNS servers manually. The IP address may change at any time.
Sticky When you select Sticky, the subnet mask and default gateway are obtained automatically. You must enter the IP address and IP addresses for the DNS servers manually. The IP address does not change. However, the subnetwork that the device accesses may change if the subnet mask and/or default gateway change. This helps load-balance subnetworks.
Manual When you select Manual, you must enter all of the IP address settings manually. The IP address never changes.

IP Address Setting

The table below is a quick reference that shows which addresses that you must enter manually and which are automatically obtained, depending on the address acquisition method.

Address Info DHCP Sticky Manual
IP Address Automatically obtained Entered manually Entered manually
Subnet Mask Automatically obtained Automatically obtained Entered manually
Default Gateway Automatically obtained Automatically obtained Entered manually
Priority DNS Entered manually Entered manually Entered manually

Maximum Transmission Unit (MTU)

The maximum transmission unit (MTU) is the size in bytes of the largest amount of data that can be forwarded. The MTU range that you may set is 576 to 1500, and the default is 1400.

A larger MTU that you set may result in greater efficiency because each packet carries more user data while protocol overheads, such as headers, are the same size regardless of the MTU set. The greater efficiency means a slight improvement in overall throughput, with fewer packets processed for the same amount of data.

However, larger packets on a slow link take more time, causing delays for packets that follow and increasing lag time and latency. Also, if a single bit is corrupted in the transmission, the entire packet must be retransmitted. On some networks, larger packets are more likely to be corrupted. In spite of the downsides, large packets may still have a net positive effect on end-to-end TCP performance.

For information on how to improve network throughput, see Network Optimization on the Wii U.
