I have always been very reluctant to upgrade for fear of losing settings or serial numbers and would like to know if it is that much of an improvement to upgrade to 10.1.4. <br>I know that it is largly directed towards security issues and I am very nervous to do it. I don't want to lose any of my router settings either.<br>Now that I have talked about it, I think I will wait for the next major update (10.2 ?)<br><br>
