Re: Intel Wireless-N 7260 fails to connect WLAN and Bluetooth with Windows 8.1

Update 8/10/2014

The latst Bluetooth driver (v.17.1.1406.01) does not properly load upon cold start. Disabling/Enabling Intel(R) 5 Series/3400 Series Chipset Family USB Enhanced Host Controller - 3B34 in the device manager takes care of that. The Bluetooth cannot be turned off and on via the driver. This laptop did not come with Bluetooth and the bios may be part of the problem as far as this is concerned. However, the prior driver (17.0.1405.456) while also not loading upon cold start, would allow the Bluetooth to be turned off and on via task bar button and options.

After installing the v.17.0.5.8 wi-fi driver (one month ago), the 7240 did not consistently reconnect upon resuming from sleep.  Before giving up and downgrading the driver, I noticed that the option “Allow the computer to turn off this device to save power” was checked (what is the default setting on the driver?). I unchecked it and also uninstalled the Lenovo Thinkvantage Access Connections utility that I never used. I don’t know how it works, but since it is network related, I thought “let’s see what happens if it’s gone.” Since then, about 6 days ago, I have had no problems with lost connections after resuming from sleep.

The driver settings for the network card are as follows. I am running Win 7 x64 and using an RT-ac66 router.
