How do I secure my wi fi so my neighbors cannot use it

Sounds like your WiFi settings got changed to unsecure or you have a neighbor with the same WiFi network ID (SSID) that is confusing your iLive platinum.

Try changing the name of your WiFi network and confirm that you have WPA2 security enabled.

camera distance may be too far from wi fi source ie router or access point ? possible solution use a wi fi range extender.
Neighbours Wi Fi interfering with your WI FI . possible solution change the channel used by your wi fi from auto to channel 3 or channel 6 . This ensures channel spacing from neighbors if they are on auto as well . Setting in wi fi access point or wi fi router

can you log into your wi fi router admin account ?
Can you try changing the channel from auto to say 3 channel numbers higher than the lowest channel number available . This is in case you have neighbors with wi fi that might be interfering with your wi fi signal .

Wi-Fi provides wireless Internet access over distances of up to 100 meters (00 feet).

To use Wi-Fi on your phone, you need access to a wireless access point or "hotspot". The availability
and range of the Wi-Fi signal depends on the number, infrastructure, and other objects
through which the signal passes.

Turning Wi-Fi on and connecting to a wireless network
From the Home screen, press MENU, and then tap Settings > Wireless & networks.
Select the Wi-Fi check box to turn Wi-Fi on. The phone then scans for available wireless
networks.

Tap Wi-Fi settings. The network names and security settings of detected Wi-Fi networks
are displayed in the Wi-Fi networks section.
If the wireless network you want to connect to is not in the list of detected networks,
scroll down the screen, and then tap Add Wi-Fi network. Enter the wireless network
settings, and then tap Save.

Tap the Wi-Fi network you want to connect to.
If you selected an open network, you will be automatically connected to the network.
If you selected a network that is secured with WEP, enter the key and then tap
Connect.

Depending on the network type and its security settings, you may also need to enter more information
or choose a security certificate.
When your phone is connected to a wireless network, the Wi-Fi icon appears in the
status bar and tells you the approximate signal strength (number of bands that light up).
The next time your phone connects to a previously accessed secured wireless network, you
will not be prompted to enter the key or other security information again, unless you reset
your phone to its factory default settings.

Connecting to the Internet without a Wi-Fi data plan isn't a difficult process even for a novice at utilizing and joining wireless networks. Whether you are looking to join a public Wi-Fi hotspot network or a neighbor's private Wi-Fi network with their permission, get your computer online and browsing the Internet without the use of your own Wi-Fi data plan, saving money in the process. Note these steps to get you connected in just a few minutes.

Move to an area that offers free public Wi-Fi or to an area where you believe you are close enough to pick up a neighbor's Wi-Fi signal. In the latter case, check with your neighbor beforehand to ensure it is allowed that you utilize their Wi-Fi network. Using a private network without permission is illegal. Boot up your laptop. Allow Windows or the Mac operating system to load up fully on the laptop. Click on the wireless icon on your computer's desktop area. In Windows, you will find this icon on the right side of the bottom toolbar. It appears to be a computer monitor icon with small radio waves reaching out of it. Alternatively, on a Mac laptop click on the Wi-Fi icon on the top right toolbar in the desktop area. This icon will look like a set of radio waves extending upward. Look over the list that appears once you click on the wireless icon. This list will present all the wireless network options that are within the range of your laptop. Avoid any that present with a "lock" icon beside them, because these require passwords. If you are looking to join a password-protected network like one offered by a neighbor, request the password ahead of time. In the event of a public network at a local business, a password will not be required. Click on the network you intend to join. Input the appropriate password at this point, if joining a password-protected network. Also, choose the type of security encryption the private Wi-Fi network is using. Your computer will often have this auto-selected, but you may need to select either "WPA" or "WEP" security manually. Click "Enter" on your keyboard. If you do not have the necessary password or are unsure as to the security encryption type, either contact the network administer or click "Cancel" and join a public Wi-Fi network. Allow several moments for your computer to join the network. You will receive a notification on your Windows or Mac toolbar when it does. Launch your Internet browser of choice and begin utilizing the Internet without having to rely on your own Wi-Fi data plan

To connect to a WLAN via Wi-Fi™:

1. From the Home screen, find and tap Settings.
2. Tap Wireless controls > Wi-Fi settings.
3. Mark the Wi-Fi checkbox. Available Wi-Fi™ networks are displayed in a list under Wi-Fi networks. The available networks may be open or secured. This is indicated by the icon next to the network name.
4. Tap a Wi-Fi™ network to connect to it. If you are trying to connect to a secured Wi-Fi™ network, you are asked to enter the security key for that Wi-Fi™ network before you can connect to it. The Wi-Fi™ connection is displayed in the status bar once you are connected.

Useful tip:

• The next time you connect to a Wi-Fi™ network, the phone will remember the security key.
• To enable Wi-Fi™ network notification of open networks, mark the Network notification checkbox.
• To connect to another Wi-Fi™ network, just tap another Wi-Fi™ network in the Wi-Fi networks list.
• To scan for Wi-Fi™ networks manually, press the Menu key and tap Scan. The phone scans for Wi-Fi™ networks and displays them in the Wi-Fi networks section.

I hope this will help.

No there is only the password they set. I advise getting your own wi fi because they are paying for theirs and they dont want to give it away for free. Plus that is illegal if you break into their wi fi. Sorry but you will have to get your own wi fi.

It should work fine if the public places have open (non-secure) WI-FI. Try it at your local library.
I would not use your neighbor non-secure WIFI since it can be trace back to you and it is not fair to use your neighbor for free unless you ask your neighbor or offer to share the cost which is probably the best thing to do to reduce the cost.

First connect your router to computer with ethernet cable.
Then you can access it with following link
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
then go to wi fi security set your WEP code it is your security key to connect wi fi network.
Change it and then save settings and restart router.
Let me know if you need more assistance.
Thanks

go to settings and wifi...look for your network and tap on it.
Join your network and if it is secure it is asking for the WEP key which is on the label of the router.
Enter that kep and it should join.
if it is truely an unsecure wifi you should be able to get right on by joining it.

You may be seeing full signal but it may be your neighbors or next door

Good Luck
