Asus PCE-AC55BT; Delayed connection time.

Hi....though not a total pc dummy in general, I come close in regard to networking, adaptors, etc thus finding myself stumped by an issue that's probably quite basic, probably dealt with repeatedly elsewhere...but I haven't found it over many hours of looking so.....

General info, might it be of use.

Dell Precision Workstation T1650/i7-3770/3.4GHz running Windows 7 Pro/64.

Installed Asus PCE-AC55BT Wireless/Bluetooth adaptor.

Connecting to a Vodafone AC router & their best Fibre...
