How to block the neighbors from using my wifi account?

Hi Penny
Not exactly sure of your requirement.
An Activation Code usually refers to enabling a paid for service.
Like a game or streaming service like spotify etc

AppleTV is plugged into your TV via an HDMI Cable.
It then accesses your local in home WiFi....
To connect to the internet and your Apple Account.
You will need your WiFi Modem password initially to connect into your home network.
Then set up the AppleTV to connect to your Apple Account with your Apple ID (Username & Password)
Use the free Apple "Remote" App on your iPhone to make it easier to enter text.
Also, this might be good for entering activation codes for joining any App services shown on Apple TV main menu.

Cheers

Go over and knock on their door and ask them.

WIFI is wireless internet service. You can use WIFI on your netbook to get on the internet. You can also use a corded connection like an ethernet cable to accomplish the same thing.

In order to use WIFI, you need to access to the account that is providing it. There are many ways to get access to wireless internet service. Some places have "WIFI hotspots" and if you are in range your netbook can pick up the signal by clicking on the little button marked "wireless" (or look for the picture of the wireless antenna) to have it search and connect. Places that include wireless hotspots or free WIFI are Starbucks, and local colleges or Universities. You can purchase your own wireless internet service from any local provider like Version or Charter Cable. Make sure to ask for a DSL modem with a wireless connection built in when you order service. Your account name and password are listed on the bottom of the modem and/or router. If you are unsure of which ones to use, call your provider for more details.

Wireless hot spots usually do not require passwords. Just click the wireless button to pick up a signal on the front of your netbook and follow the prompts on the screen to connect.

I would suggest purchasing your own connection instead of tyring to find an unsecured (no password protection) network that belongs to a neighbor to try and use theirs. The cost is approx $ 25 - $ 30 per month. Check with your local telephone provider for the deals available in your area.

The SB4100 is a digital modem that uses cable TV network to provide broadband Internet access, it can't work with an analog telephone line, for this type of Internet access (also called switched Internet connection), you need an analog internal or external 56K modem, and also you'll need a user name and password (an account) from the Internet provider service (ISP) ; for a temporary Internet connection maybe a prepaid cellular modem (GPRS, EDGE, 3G or 4G) USB type could help you better.

This could be caused in a power surge resetting the next door's wifi modem or it could be that your neighbors just decided to put up a security password and unless you are an expert hacker, there's no solution for free wifi. sorry

Router passwords are case sensitive, be careful when entering the password. If you can, ask the owner of the router to enter the password for you. If you're using a neighbor's wifi network, you are pretty much out of luck unless they give you the password.

If you are trying to connect to her internet connection, you use her router.
You cant connect 2 routers to one modem, unless you set one up as a repeater.
Just ask her for the wifi password, and connect through her router
