To connect a Wii U to your wireless home network:

1. From the Wii U Menu, click System Settings.
2. Using the Left Stick, select the Internet icon and press the A Button.
3. Select Connect to the Internet.
4. The Wii U will search for available Wi-Fi networks in your area.
5. Once the search completes, use the Right Stick to scroll up and down through the list of networks and select the name of your Wi-Fi network.
6. If prompted, use the on-screen keyboard to enter your Wi-Fi network's security key (wireless password) and select "OK" when finished.
   • If you receive an error message stating The security key you entered is incorrect, the security key you entered was not a valid security key.
7. The Wii U will now perform a connection test.
   • If the connect test fails, select OK to receive an error code and detailed information on why the connection test failed. You can use Nintendo's Error Code Lookup Tool to get information on resolving the error.
   .
8. If the connection test is successful, select OK to continue.
9. When asked if you would like to make this your default connection, select Set if you wish this to be your default connection or No if you do not.
10. The Wii U will now ask you to perform an update, select "Update" to perform the system update, or select "Cancel" to skip this process.
    • Nintendo recommends performing the system update as this will ensure you have access to recently released applications and services.

There's always a reason but who cares if there is a good solution. Try rebooting your wifi router and then your PC and see if the connection returns. Also try to delete your WIFI network connection. Then reboot and it should return and so may your connection! If its a secure connection check if your password is correct by opening your WIFI network connection by double clicking it and clicking on wireless properties and then the security tab. Confirm your security key exists and is correct.

not always, but often the reason it takes several seconds to respond, then tells you it timed our or failed is an incorrect password.

Hi,
It is possible that your Network key/Security password is incorrect one reason why you can connect to he Network but not get any internet, or the router setting is set only to provide wireless internet on a number of devices all at once.
Depends on the router you have check the setting and see if it is set to limited number of devices that can connect to the internet or try disabling the Network/Security Key and try connecting to the network and see if you can get internet, if you do then the Network key is the issue.

Hi,
For security reasons, the wifi router is always configured with a key. This will prevent unauthorized persons to access the internet via your wifi router.
You have to ask the administrator who configured router to get the key and you have to provide the saem when prompted in your computer/laptop in order to connect to your office router.

I hope this is helpful for you.
Thanks

Good day! There are things you need to check to successfully connect the printer for wireless connection.
1. Make sure the wifi light on the printer is solid orange before continuing. If not, go to Setup > Network Setup > Reset Network Adapter to Defaults. Wifi light should turn off, then wait for it to turn solid orange.
2. WEP key can be ASCII or HEX(hexadecimal) depending on what was assigned to it. You may be using an incorrect WEP key. Just to make sure, access your router setup page and double-check the WEP key assigned to it. If you don't know how to access the router setup page, you can always ask assistance from either your internet service company or the router's manufacturer.
Once you get the correct WEP key and wifi light solid orange on the printer, try connecting the printer again for wireless connection. Good luck!

the reason for this part to fail differs along with the difference of the type of connection you are using to connect your Xbox 360 console as follows:

a. Direct connection to modem:

1. Make sure first no other devices connected to the modem at the same time as some modems has an Ethernet port along with a USB port so, you might think you can use both at the same time & connect the PC through USB with the console through Ethernet & that's incorrect so, we need to disconnect the PC first.
2. Turn the modem off then turn it back on after couple of seconds (by turning the modem off I mean to unplug it from the wall outlet even if you have a power button for it), then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Restore to Factory Defaults" and when it ask you to Apply Settings select "Test Xbox Live". 3. If it's still not working we need to get the Physical Address of your PC to put it on the dashboard of your Xbox 360 console as some cable companies are preventing any unknown MAC Addresses from connecting, to get the Physical Address of you PC connect the PC only to the modem then follow these steps here, the physical address will look like this 00-E0-98-C1-88-C2.
4. Go on the dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Edit Settings” then “Additional Settings” tab then select “Advanced settings” & put the Physical Address of your PC without the dashes on the “Alternate MAC Address” part and select "Done", when it asks you to Apply Settings choose “Test Xbox Live”.

b. Wired connection to router:

1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults", when it ask you to apply settings select "Test Xbox Live".
2. Turn the router off then turn it back on after couple of seconds, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
c. Wireless connection to router:
1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults", when it ask you to apply settings select "Test Xbox Live"
2. Go on the Dashboard of your Xbox 360 console to the "system" area then "Network Settings" then "Edit Settings" then select your wireless settings part down there "Wireless Mode, Network Name,..." the console will automatically then search for your wireless network and when it find it and you select it, it will ask you to enter your wireless key which is called WEP or WPA key - you can find it written on your wireless router or then you need to contact your ISP (Internet Service Provider) to get it from them - when it ask you to apply settings select "Test Xbox Live".
3. Just a kind of higher security that some router may use than the WEP & WPA key, you have also to accept the Xbox 360 connection to your wireless network on the router settings, you have to access to your router settings as mentioned before to check on the wireless security part whether your router apply a MAC filtering option, which is an option that blocks any unknown MAC address (the ID of any device) from accessing to your wireless network, and if it applies that kind of security you’ll find your Xbox 360 MAC address on the list there so, allow the Xbox 360 to get connected to the network, or even you can just turn off the MAC access control option instead of that, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
4. If it's still not working, you can put the Xbox 360 console - as a trial - in a closer position to the router to see wither it's going to pick up an IP address or not.
5. If even after you turn off the MAC filtering option on your router settings your Xbox 360 can't still get connected to Xbox Live you need then to update your router firmware (The router software) and if you don't know how to do so then call your ISP (Internet Service Provider) to assist you with that, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
d. ICS (Internet Connection Sharing):
1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore to Factory Default" when it asks you to Apply Settings choose “Test Xbox Live”.
2. Allow the ICS option on the PC as mentioned before, then test Xbox Live.
3. If it's still not working, set the IP Settings manually to be:
IP Address: 192.168.0.2
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.1
Then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
4. If it's still not working, you can get the IP address of your connection from the PC as mentioned before then set your IP manually on the Dashboard of your Xbox 360 console using this IP address, when it asks you to Apply Settings choose “Test Xbox Live”.
If you faced any other kind of troubles with this part failing even after you tried these steps please check me man 

Hi make sure once you connect that you enter the 'password' / key to connect to the network. You can right click on it and select 'connect to this network'. Then it should ask you for the network key once it is connected. Once entered you should be able to use 'his' network.

Let me know if this worked ok for you.

Hi here is a tutorial how to connect up.. support.microsoft.com/kb/314897 One has to ensure that the wifi settings are all the same.. also the Logon & password must be entered as well as any WAP encrytion that maybe used.. It is a good idea to ask the person who administrates the WiFi at the hotel for the setting so you can access and logon to their network.
