Hello.  I have a Dell Inspiron 1525 with a Dell Wireless 1395 WLan Mini-Card.  We've had it for a year and a half and have had the same problem all this time.  We're connected to the internet via cable from Time/Warner.  However, it frequently boots us off the internet or we can't connect at all.  The cable people said it was deffinately the wireless card.  When we talk with Dell, they say that it's a software problem.  We have two other computers that have no problem connecting wirelessly to the internet.  This is the only one that has been having the problem.  Any suggestions?
