When you say sending out probes what do you mean sorry?
Are you by any chance using an Asus router ?
This was an issue with Asus a couple of years or more ago but as far as I know it was fixed in a firmware upgrade
I wouldn't worry about it as long as there's nothing in the log to say that the device actually managed to authenticate in the first place
My next door neighbour's Sky box frequently tries to connect to my SH2, As it's never succeeded I just let it waste it's time 😀
Ah, i did wonder if this was a possibility.
So far no success here either, just page's of nonauthentication so, it can happen every minute for a few hours, then nothing for a few days! Never mind, atleast it's not just me haha!
