How To Connect to the Internet

''' N.B. This page covers how to connect to the Internet via Wireless or a wired connection. For instance if you are trying to connect to a wireless access point at a coffee shop or the library, or if you have a home broadband or DSL connection (typically from Comcast or CenturyLink in Portland). It does not cover connecting via a dial up modem or via 3G (e.g. via Clear). '''

Wired Vs Wireless
Laptops from Free Geek come with wireless already installed, Desktops do not. If you have broadband at home your broadband provider will typically have given you a wireless router. These are also often available in the Free Geek Thrift Store at low cost. If you have a desktop you have a choice of installing a wireless card or using a wired (ethernet) connection (wireless routers also allow you to connect to them via an ethernet cable as well).

Wired connections are cheaper (wireless cards cost from $15 up + the cost of the router while an ethernet cable can be brought from the Thrift Store for $2), faster, secure and very reliable -- for this reason they are typically favored by businesses. Wireless connections, on the other hand, allow you to eliminate unsightly cables, hook up computers in other parts of your house, easily, and allow a greater range of devices to connect to the network (e.g. smart phones and tablets). On the downside they can be slower and less reliable: interference from other wireless routers, wall or floors between the computer and the wireless router, even the leaves on trees in the wrong season can all cause problems. In general, though, the convenience outweighs the potential downsides for typical home users.

If you want to put a wireless card in your desktop you need to be aware that some models work much better than others and some won't work at all with Linux. You should contact [Tech support] for advice before buying one (staff in the Thrift Store will also be able to ensure you get one that is compatible with Linux).

Before You Start
If you have broadband at home you need to make sure it is hooked up correctly. You need to make sure the cable modem (or set top box) is connected to the wall socket and that the modem is connected to the router via an ethernet cable plugged into the hole marked 'Internet' or 'WAN'. These should have been supplied with your broadband kit. Ethernet cables have a plug on the end that looks a little like a phone plug, only bigger, and they look like this:

They come in a variety of colors but yellow seems very popular with broadband providers.

How to Connect Via Wireless
On the top panel of your computer you should see the network symbol. Before it is connected to a network it looks like this:



If you left click on it it should show a menu like this:



This should show a list of wireless networks you can connect to, if none are showing up, or it says wireless disconnected please see the Troubleshooting section below. (I have fancy transparency effects turned on if you are wondering what is showing in the background).

Here there are four networks. You should note that all the networks apart from Free Geek have padlock symbols next to them. This means that they have encryption turned on -- you will need a password to connect to an encrypted network. The numbers of bars lit up tells you the strength of the wireless signal. To join a network just left click on its name. You should see the lit up bars on the icon on the top panel move up and down for a while. If you need a password a box should pop up, at this point, so you can enter this. If all goes well the bars will stop moving and the symbol will have changed into this:



You might also get a notification message pop up telling you have made the connection. You can check by moving your mouse over the network icon: a bubble will pop up showing you details of the connection.



If you left click on the icon you will see that the network has moved places in the menu
