So I finally got Ubuntu 10.10 working on my computer. The Internet works fine when I have my Ethernet cable plugged in but when I try to go on when it is unplugged it says I have no wireless connections and I don't know how to find them.

help?

First make sure your wireless card is supported by the Linux. Then second, configure it via network tool.

In the top panel, check if you wireless icon ( if you are not connected there will be red exclamation mark). Right Click and check if wireless is enable. If its enabled, left click and see what all wifi networks are available. If you can see some name there but not yours, probably your router is not broad casting the SSID.

You may need wireless drivers. Check in system>administration>additional drivers.

I have no idea how to tell if it is enabled or not. I do get the exclamation, when i right click it brings up a menu with:
Enable Networking (with a check next to it)
Enable Notifications (with a check next to it)
Connection information (greyed out and unclickable)
Edit connections...
About


and i have checked the additional drivers and nothing comes up.

Edit connections.

First of all, lets see if your wireless is detected by the system.

do

lspci or lsusb
command on terminal as root and see the output if your wireless chip vendor name is mentioned.

Seems like system support your realtek chip. Now lets check if your wirelesss network is enabled.
Do this:

ifconfig -a

as root.
