All right, I've got an Archer A10 here that I've changed the LAN IP to 2.1 (replaced a slower router, I've got my little network here previously set up for that IP).  Whenever there's any sort of power outage, even just a moment, the router resets its LAN IP to 0.1 as it was out of the box.  It's not doing a full reset, I have some forwarded ports that it keeps, it's just the LAN IP (and DHCP pool) that it switches back to default.  I updated the firmware when it first happened last fall to see if that would solve it, and it still happens.  I change the IP back to my range, save, all works well.  The next time there's any sort of power interruption, it switches that one setting back to default.  It seems like it's a "that's just what it does, you'll have to live with it" situation.  Any suggestions?  My choices seem like put it on a UPS, switch my network to operate on the 0.1 range, or change the router.

Thanks.
