Have this card finally found and very quickly get - Super Supplier, one can only recommend always happy. After some browsing on the Internet, for example under XPS-Forum.de, I have discovered the appropriate driver and after the establishment that thing runs perfectly. One need but absolutely the Wireless Manager Ericsson (you can also get in the forum, just for items for example Dell 5530 search) the Dell direct (Dell Conection Manager) is lousy and should rather not be used MMN. (Which, inter alia, no automatic connection with HSDPA devices here!). The quite annoying. Conclusion: strong buy recommendation especially at this price and with this good dealer.
