Hello Rambomhtri, I am sorry to hear you are having problems with your N7260 adapter.
We reported this issue a few weeks ago and there is a new driver version available. Please uninstall the current driver version and download and install the newer drive. Download Center
Since you are using Windows 8.1, I really recommend you to run all Windows updates before performing these changes.
I have everything up to date, all, included Windows Update. I have the Bluetooth driver 17.0.1405.460, x64 edition. The issue is still there. The most unbelievable thing is that BEFORE I formatted my laptop, BT worked great, and I had installed the 17.0 version. Of course, I've tried that one but it doesn't fix the problem.
OK' I've got it!
One of the first things I do is to disable all unnecessary startup programs, and I had deactivated "Btmshellex", and I think it's related to Bluetooth. So I've activated it and restarted the laptop, and BOOM!, fixed, now it appears a prompt when I receive a file from the PC. Thanks!
Excellent. I'm glad to know you were able to fix this issue.
