Product works fine in E-Tower PC with O.S. WIN Vista Home Basic 32 bit.
Clear Hot Spot Speed = 54.0 Mb/Sec
Found unit on clearance.
Contacted Cisco / Linksys initially when it did not work.
Little support interest because product is not in production anymore.
PCI board only needed to be reseated in socket to make it work.
Worked fine thereafter.
