I think we're looking at an unaddressed bug, and I'd be curious if the original poster was running Vista 64-bit as well.
Hi dwmorse
I don't think we're looking at anything of the sort. A quick look at the spec for the Studio 1537 on the Dell website shows that only one WLAN card is installed, which is exactly the same one I have in my Studio 1737. If that's what you have, and it's what Dell says you should have, then the cure is very simple
First things first, back up your system, as I take no responsibility for any data loss or other operating system failures. Everything is at your risk, not mine (but there's really no risk if you follow the instructions)
First, go to the Dell website and download the latest drivers for the wireless LAN card in your Studio 1537. You can double check the model of card by going to Control Panel, Device Manager and checking. I expect it to be a 1397, although it could possibly read as a 1510, which has the same drivers
Second, from Control Panel, Programs and Features uninstall the existing Wireless LAN utility. I no longer have it installed so can't give you the exact name for it but it will be quite obvious which one it is
Third, unpack the drivers you just downloaded from Dell (it should be a file called R206848.exe). Allow the file to unpack to its default C:\Dell\Drivers\206848. Once the file has unpacked you will see a message asking you to click to finish. After you click finish, the drivers will start to install but at this stage click cancel. Do not let them install
Fourth. Go to Control Panel, Device Manager and look for an item under Unknown Devices that says it is a Network Adaptor and has a yellow exclamation mark next to it. Right mouse click, select properties, select the Driver Tab and then click Update Drivers, then "Browse my computer" and point the dialogue to the location of the unpacked file (C:\Dell\Drivers\206848). The drivers should then install but the utility will not. Reboot the computer and you should no longer have the problem
As you are using 64 bit VISTA please double check that you have the correct drivers by using your service Tag on the Dell website. I have no idea whether the drivers are the same for both 32 and 64 bit but if in doubt post back here before you go ahead
Let us know how you get on
