2 days and nobody answered...so...
I cannot help you with the Wirie....but I can tell you that I used an Alfa AWUS36 (?) for a few years before stepping up to a decent on-board Wi-Fi system!!
I went for the Bullet-based system from Island Time PC...
Best $200 investment I made in a decade!!
(100 times better than a Wirie and about the same $$$)
Marine WiFi Systems
(although Bob now uses/recommends the Groove, my old Bullet and 12vdc router have worked flawlessly for years now!)
Bob is not only a knowledgeable guy about all of this, but is also a sailor and part-time cruiser himself!
I recommend him highly!
Hope this helps..
