wireless card

[Douglas Pollard]

I have a linksys wireless card that I have messed with off and on for a  
week.  Ubuntu can't see it. Ihave been in terminal  and have found no 
sign that it exists.  Have tried installing drivers,  Widows drivers, 
nothing from any of that.  Is there a way to find out  that it might be 
faulty  or that it works at all.    I have thought about plugging it 
into a different computer  but that seems kind of extreme .   Any 
help??    
                                                            Thanks,   Doug
