I have upgraded my Samsung NP880Z5E with SSD, 16Gb Ram, Windows 8.1. The last part of the upgrade was to fit a faster WiFi card so I replaced the 6235 with the Intel ac 7260. All is well with everything apart from Bluetooth which will either not start or have problems (code 43) showing in device manager with driver 17.0.1403.438. The wireless seems to be working fine with driver 17.0.6.1
I have tried most things apart from a factory reset. Any thoughts gratefully received.
