5268ac Shows up as an active connected device in the device list

@FozmanX

Please provide the level of software installed.

@ATTDSLCare

I have 10.5.6.529428-att installed as current version.

This sounds like a firmware bug. I have to assume that you power reset the 5268ac but if you haven't, please do so.

At this point, I am going to recommend that you contact AT&T for service and convince them that they need to send someone out to replace. Only problem with that is that at some point the new 5268ac may get the same update. It is worth trying.

@ApexRon Yes I have reset the Gateway a few times and also cleared the device list. After clearing the list it still came back. Please see my next reply.

@my thoughts Yes, the new firmware talks about band steering and has a warning on the Wi-Fi tab with instructions on SSID and security settings. Are you saying that the gateway being in the device list and having an IP is because of band steering? If so, I can live with that. I just hate unexplained things when it comes to network protection/security. Thanks in advance.

I also have this '5268ac' showing up in my list of connected devices, but i have NOT received the firmware upgrade yet and am still on 10.5.3.527283-att. I've done two factory resets and it reappears within a few minutes of the system booting back up. And since I do not have the new firmware, I would think it's not connected to band steering since I'm not supposed to have that functionality yet?

I too see this device just as you do with a different IP than the RG itself (although within the same range block) and its 'attached' to the 5ghz wifi. I can ping it but have no idea what the heck it is or what its for.

I am on 10.5.6.528454-att as of today and that is when it appeared.

I too get the same warnings on wifi about keeping the SSID same and passwords the same. I am not interested in that.

I disabled 2.4ghz wifi completely and just use the 5ghz band.

I have not had any issues I know of or strange errors in any logs but find this suddenly 'new' device showing up as a question I would indeed like explained.... Hmmmm

Yeah...nothing like unexplained things showing up on your Wi-Fi network eh? Don't bother calling "tech support" either. They seem clueless...

 I also see this on my devise list tried reset to factory default and the devise come back. 

5268ac shows up at 192.168.1.75 similar to the screen shot above except the SSID  shows "?" in the value column.   Turned off everything but it is still there.  Don't like unknown things on my network either.  

I have the same issue. I have U-Verse Internet but do not have an AirTies Wi-Fi Extender. But my network shows an AirTies device with its own IP address. Is it possible that my neighbor unknowingly connected his wifi extender to my network by mistake? What should I do to remove the device? I've tried talking to my neighbor but he is never home. Any suggestions?
