I have a Dell Studio One (1909) All-in-One that was new in Aug 2009. The wireless network card (Dell 1397 WLAN mini card) ceased working after a Windows update in early April. As part of the troubleshooting I installed Windows 10 Creator's Edition (v. 1703). The Dell 1397 did not offer Bluetooth.
So I replaced the old (Broadcom) card with an AC-7260 HMWG.R PCI-e mini card. Windows found a driver during first startup and Wi-Fi is working. But the Windows troubleshooter says there is no Bluetooth device. I have now installed the Intel driver (v. 184.108.40.206) and the Intel Driver Update Utility tells me there are no updates available.
Should the Bluetooth device on the AC-7260 work on this computer?
I have just had a thought that perhaps the Dell slot does not provide a connection for the Bluetooth part of the AC-7260?
These adapters are not to be used for upgrades by the user:
And, doing so may cause problems:
Best to contact Dell regarding adapter upgrades or replacement.
