It's not at all strange to see this but I didn't find what security you used.
WEP is broken by small children in seconds (about 15).
WPA is broken in about 2 hours by teenagers.
WPA2 is broken in about a day by adults with credit cards.
There's a lot to cover about security on WiFi but let's hear more from you.
I have an asus rt-n66u hooked up to my arris wifi modem (set to bridge).
all firewalls are set to on. my wireless devices are android phone, apple phone, satellite receiver, notebook, blueray, and a Microsoft surface tablet.
for some strange reason a verizion Motorola droid keeps showing up on my network when I look at network map on my tablet and pc. I only see its mac address. its very strange that it seems that I don't see it on the router itself, just my own wifi items (I think I don't see it)
anyway how can this happen? I have wpa2 set up and do not have guest acess on.
thanks for any help.....
