Thanks for advice. Ive upgraded ap with latest firmware.Cant download latest drivers for card the file is always corrupt Ill keep trying though. Followed link from wireless section and downloaded atheros drivers but keep having same problem.Reset ap no difference.Deleted all profiles best I could and changed ssid still no difference.I suppose without another ap or card I cant tell which is the problem device? They are both new so I suppose a long trip back to the shop.

Thanks again.
