Looking at the wireless statistics on a TL-WR740N wireless router, I sometimes see the MAC address "00-20-00-A5-22-1A" connecting, with the current status being "STA-ASSOC".

The manual actually shows exactly this current status as example on page 52. I don't know this MAC address, and it has sent packets to the router, but I haven't seen received packets yet.

The router uses WPA/WPA2 with AES as encryption, which is what it shows when my workstation connects to the router.

Does anyone know what STA-ASSOC is, and if someone have access to the router?

This question came from our site for system and network administrators.

I would think it's "Status: Associated" – l0c0b0x Sep 9 '11 at 20:39
@l0c0b0x : The manual also lists something called STA-JOINED. Does that make sense in this conjunction? – Sandra Sep 9 '11 at 21:57

Station associated. Not sure what device it is though.

What could that mean? Perhaps another wireless nearby? – Sandra Sep 9 '11 at 21:55

Hi I just found out what it is:

STA-ASSOC is a device that was already associate to the wi-fi router and is standing by connection (trying to connect-password changed maybe).

STA-AUTH - device awaiting authorization from router (maybe you had changed the password and the device is trying to reconnect but with the wrong password).

00-20-00-A5-22-1A is a Lexmark print server.

You can't MAC address filter such stations according to my knowledge. PS3 and iPod tend to take on such roles especially when MAC filtered.

This does not seem to answer the question though. – Kevin Panko Nov 4 '13 at 3:56
