Able my chat - Facebook Social Network

Is it just facebook or your internet connection ??..
The Facebook Chat feature allows you to send and receive messages in real time with friends who are online.
Your chat box reveals a list of available friends you can chat with by clicking their names.
For those times when you're not up for chatting, you can choose from several different privacy options, including disconnecting Facebook Chat.
You can opt to disconnect it completely, or just partially allowing chat availability for certain people and not others.
You can reconnect in a few quick steps.
Facebook Chat Availability

Your Facebook Chat availability determines how you appear in your friends' chat lists.
When you're logged in to your Facebook account, your name appears in the chat sidebars of any friends who are currently logged in.
When you set your chat preference to available, a green box appears next to your name.
When you're available, but idle, a grey moon appears next to your name.
When you're unavailable, your name appears without an icon.

Adjusting Chat Availability
Adjust your chat availability to control the visibility of your name in friends' chat lists.
Sign in to your Facebook account and click the "Chat" box in the lower right corner of any page to open your chat list.
Click the "Options" icon in the upper right corner of the box.
Click "Go Offline" to disconnect your chat availability.
If you're using the Facebook Chat sidebar, click the "Options" icon in the upper right corner of the box. Click the "Chat" box to open the sidebar if it isn't showing up on your home page.
Click the "Available to Chat" option to delete the check mark, making yourself invisible and unavailable to chat. Click the "Limit Availability" option and use the resulting pop-up to choose which friend lists you wish to remain visible to. This allows you to chat with some friends without others knowing you're logged on.
Disconnected Facebook Chat
Once you disconnect Facebook Chat or limit your chat availability, your online presence will be invisible to other users.
You can still browse the Facebook site as you would normally.
The appearance of your chat list won't be altered by your availability; you'll still be able to see which of your friends are online and available to chat.
That is, as long as their chat availability isn't hidden or disconnected.

Your Chat Messages

If a friend attempts to message while your Facebook Chat is disconnected, the message will be delivered to your Facebook inbox.
You'll receive an on-site notification, as well as text or email notifications if you're set up for that, alerting you that you have a new message in your inbox.
Click the "Message" icon that appears in the upper left corner of any page upon signing in to your Facebook account.
Any new messages will appear in the drop-down list. Click the "See All Messages" link at the bottom of the box to access your inbox and respond to any messages.
