Hi Ana,

I hope you're enjoying using Kubuntu despite these issues.  Let's hope 
we can help you get them sorted out.

There are a couple of things that might have happened here:

   1. Your wireless card might be turned off by a hardware/firmware
      switch - on some laptops it's a little mechanical switch or button
      around the outside of the machine somewhere; on others it's an Fn
      key combination.
   2. Your networking might have been turned off in software.  I'm not
      sure what it is in KDE (which is the GUI in Kubuntu), but in GNOME
      (the GUI in standard Ubuntu), you can right click the network
      settings applet and turn it on and off (both wireless
      specifically, and networking in general).  Someone else on the
      list might be able to advise on the exact method for Kubuntu.
   3. There might be some bug with your wireless card.  My Dell Latitude
      D830 is affected by a bug whereby if it is booted with the
      hardware switch on, it turns off at a certain point in bootup and
      won't turn back on.  If i boot with the hardware switch off, it
      turns on successfully after the driver has loaded.  If your laptop
      has an Intel wireless card, it may be affected by this or a
      similar bug.

Personally, i don't find that a reboot fixes much with wireless stuff on 
Linux, so i would use that as a last resort.  In general, you should 
only need to reboot Linux when there's a kernel update, or certain other 
core software (update manager will tell you when it's necessary).

A quick Google search indicates that the printer has driver support for 
CUPS (, but the 
OpenPrinting database has nothing 
(, so some fiddling might be in 
order to get it working.

To execute Windows programs on Linux, you need to install a product 
called "wine" - you can do this through the normal software installer 
(i'm not exactly sure where it is on Kubuntu, but i'm sure it will be 
pretty obvious).  After you install wine, .exe programs should start 
using that when you open them in the file manager.  Some Windows 
software works really well in wine - other software doesn't work at 
all.  If the latter is true in this case, you should find some 
alternatives if you search in the software installer.
