Sorry about that--looks like the link was broken.  Driver is here.

Alan,

I found a 64-bit Windows 7 driver for the Dell 5530 mobile broadband card on support.dell.com.  It was on the page for the Latitude XT2, but since the card is the same, it should work on your Studio XPS as well.  The driver is 

thanks i will give that a go, still got vista 64 installed atm as i was holding off reinstalling win7 untill i have all these issues resolved, just tried to install it as a virtual machine to check out all the drivers unfortunatly my system wont let me install virtual 64 bit machines. might backup and install win7 this eve, ill post if it all goes ok :)

sorry to post again.

having some really wierd problems now. I have managed to install the mobile broadband card now used my vista x64 drivers and they seemed to work.

but i still have a base system device which i can not phatom what it could be, Plus every time i restart the machine the quickset thing for the the sound etc buttons dont seem to work i have to reinstall it. network seems to have really slowed down but that could be anything..

i think i may be best off reinstalling vista64 untill i get my upgrade cds in the post..

hoping i migh have more joy with them.

hi again, well i have installed windows 7 x64, all fine expect from the hspa card and something coming up as base system device :S

that link i downloaded and tried to install that driver but its coming up about a 5540 card and can not install when i have a 5530 card.

no ideal what that base system device is :(

i am a little bit peeved off with dell atm, as altho i have had my laptop for almost 2 months my service tag is still not on the system and i can not access any of the drivers by putiting in my service tag i have to navigate to it manually plus the link for install factory installed software doesnt work ( i think its because it scans for a service tag but as mine isnt in the system it doesnt work)

thanks for trying to help tho, any other ideals?

For the base system device go to the chipset listing for the Studio under the win 7 os and download and install the Ricoh card reader driver 

I had the same yellow device when I test loaded the 64 RC version on my 1640 and found that cured it. 7 runs very well on the laptop and as soon as I get my desktop fully reloaded with win 7 pro, I will be installing it on my Studio.

hey thanks dave that fixed my base system device problem :)

only thing bugging me now is the factory installed software like the vodafone connection thing, and the dvd player etc going to speak to dell again today to see if they have got anywhere if my service tag being registered yet.

thanks again

the 'base system device' is a ricoh cardreader device.
