Your have found out what your wireless is. It has been around for
awhile so should not be a problem.
BTW, it was one command, not two separate ones. The | line is a pipe
used as part of the command. It does not matter because you found out
that your card is Realtek RTL8191SEvB.
With that information you should be able to get a driver and since it
is common I would be surprised if it was not already installed.
Wireless does not work OTB in Linux as in Windows because Linux is
more secure. The basic principle is that nothing is changed without
your permissions. Since Wireless is a possible security problem then
it is handled differently from wired. You need to set it up on both
Windows and Linux with a encryption scheme.
The good news is that if you do not have a Linux driver then you can
use the Windows one, so you should be able to get it working one way
or the other.
First I would try setting up the wifi and assume that you have a
driver. You need to right-click on the network manager which should
have an icon in the notification area (Windows speak = system tray,
but in Ubuntu it is top right). I am not in Unity (Ubuntu's desktop
now, but am in KDE, but it is the same principle). Choose the settings
or options. Click on the wireless tab. Add a new wireless network. If
you have one set up under Windows for your router then use that SSID.
That will be what others see from the outside when they scan for
networks. Click on the type of encryption that your router is set up
for (I urge WPA over WEP because WEP is very crackable). Add your
password (this was all done previously when the router was set up, you
are just giving the router information to Ubuntu). Make sure that you
tick the box that says connect automatically. Once it is setup it
should work right away, but if not try a re-boot. My desktop has no
wifi built in but I can switch usb dongle brands and it does not seem
to matter. I just shut off the network and re-start and it just works.
If it does not work then you have a driver issue. That involves
installing some packages. I would first look at Additional Drivers in
the menu. If that does not produce one then you need to get a driver
or use the Windows one.
If you are using WEP at the router that could be the source of your
problem and you may have to amend the settings to enable WEP.
Sometimes changing the network manager to wicd will do the trick.
These things take time and it is not easy to troubleshoot at a distance.
This is a busy weekend (Mother's day) and won't have much time to
respond. Others please jump in.
