wireless connection problems at home but not at work

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

Remove the wireless security
Is your wireless security enabled?
if so - log into the router and remove the wireless security - now see if it will connect.
if it does - log back into the router and try with the wireless security enabled again
