Asus PCE-AC66 Haswell Z87 B85 Freeze lockup hang problem by UK Gaming Computers

A little problem has been doing the rounds a few weeks now since the launch of Intels 4th generation processors and chipsets. Users have been reporting an annoying freezing lockup issue with the Asus AC66 wireless cards when combining them with a new motherboard that uses the Intel Z87 and B75 chipset.

As soon as the driver for the card is installed (from disk or the latest version from the Asus website) and the system is shut down or rebooted the operating system will either freeze as soon as it boots into the operating system or will hang on the starting windows screen.

Both Windows 7 and Windows 8 is effected and at a guess older operating systems will probably be effected to. Take the driver off or the PCE-AC66 out of the system and the computer will then operate normally. The issue is also not brand related, Asus, Gigabyte, AsRock and all other brands have the same issue.

The Solution

There isn’t one! Asus have confirmed that the AC66 1300MBPS contains a chip that is not compatible with Haswell chipsets. Full stop, end of the line and this train will terminate.

It leaves two choices – Replace the card with another wireless adaptor or wait until August 2013 when Asus will bring out a Asus PCE-AC68 1300MBPS wireless card which will have the same spec as the AC66.

UK Gaming Computers have not sent out a PCE-AC66 wireless card with any Haswell based systems.

We would encourage effected users to raise the issue with Asus directly or your retailer explaining the issue and I am fairly confident you can obtain a refund or a new PCE-AC68 when they come out.
