Here is a direct link to the driver download: IRST Download

The version that I linked to above is, which should be compatible, but is a little older than the recommendation. If the above driver does not fix the issue, then we can try the latest offering from Intel directly, but we likely will not need to.

Currently the only commonality we have been able to identify is motherboard manufacturer but even then there are some exceptions.Fear not!
