Where can I find the windows 7 driver for my dell wireless 5505 mobile broadband Express card? This one is simple. Go to the dell website and download the driver.
How do I install the driver on an dell e-series (Latitude E6400, 6410, 6420, 6430, E 6500, 6510, 6520, 6530, ...) laptop? It's not possible, because the installation fails showing the error "No a Dell compatible system" Why is that so? Probably the dell mobile broadband cards like dell 5500, Dell 5505, Dell 5510, Dell 5520 are made for DELL's D-Series products. In my case the card comes from a Dell Latitude D820 and is now installed in an Latitude E6520.
I found, that there are some people using this card on D-series laptops with windows 7. So, the OS isn't the problem. The card itself is generally compatible with the chipset etc. But, How can I istall that driver?
