I have not tried this but will in a few minutes. I wanted to make sure that I got it uploaded to ya'll. After 2-3 days of searching I found this version (106a) that appears to be the latest. I am not sure if it works with XP but the other one 105 is for SE. So maybe this one will work with XP. Here is the site that I found it at: http://drivers.softpedia.com/get/FIRMWARE/Nec/NEC-NR7700A-firmware-106a.shtml
The following files are found inside the driver download file.
