While on vacation, I power down my LAN because I can’t monitor who access it. After a five day absence, the router worked fine after I powered it up. I tried to access the admin interface later that day but I got a bad username/password error. I know it was correct because I access the router interface a few times a week. My only recourse was to reset to factory defaults then reinstall my configuration backup. Not a bit deal (down for 10 mins) but annoying.(I don’t use external methods to access the router.)
Is this a known bug or do I have to reinstall the backup configuration if I power down the router for more than a day or so?
