Like I mentioned to others, you have to have the exact I.P on the menu under Internet/Network Info. on the top line. This is the N-Fusions I.P address, and you have to type it exactly. So write that down, put the N-Fusion on channel 100 and go to your computer. Then if you don't have Winrar go to Google and download the free 30day trial, it will unzip all files and especially the rar. files like 1.47. So do this then go to Internet Explorer and at the top browser line that starts with http: , type the I.P in that line and press Enter. A little window will pop up asking for your Username type (admin) then Password (0000) and click O.K., then the Webloader window will pop up. You will click on Open then click on the file you just downloaded and it will show up in the Webloader window then click Upload, the N-Fusion will shut down for 10-15sec. count this is normal. When the N/F comes back on go to System Settings and S/W Version and click on that and see if the 1.47 is there, if so you can do a Factory Default and then scan the antennas again and you should be good to go! Good luck and let me or anybody know if it worked and if you need more help.
