My notebook is AH531/GFO with Windows 10 Pro. Original WiFi card on my notebook was Intel Centrino Wireless-N 1030. I replaced this card for Intel Dual Band Wireless-AC 7260. Everything was ok for 4 months. Some days ago Bluetooth of 7260 was broken - WiFi was working. Drivers were reinstalled but didn´t solve the problem. In this fact I replaced for the old 1030. BT and WiFi works. I thought that 7260 card is broken. No errors on OS but I can´t connect my BT mouse or mobile phone.
