I don't know how long this has been going on but I recently noticed I'm getting a lot of entries like this one in my Actiontec's Advanced System Log:
Cannot find cache entry for mac 00:1d:c9:93:09:e4 ret=-1
[repeated 3 times, last time on Dec 13 15:19:09 2015]
I'm not noticing any performance problems but I can't help wondering what those log entries mean. Is something amiss, or is it nothing to worry about?
If anyone has any insight, including where I might a list of what Advanced System Log file entries mean, I will appreciate the help.
Thanks in advance.
