I am using UBUS on OpenWRT for device tracking on a Linksys ACM3200 router. This worked perfectly till two weeks ago. I noticed my phone was considered “away” when I was at home. I noticed that this happens only on the 5 GHz Wifi. In the phone the private MAC address is turned off, so the phone is recognized the same way on 2.4 as on 5 GHz.
The connection is not lost. I can use the wifi on my phone. In the DCHP-table the phone is there and has an IP in the correct range with the correct MAC.
There are no error messages. Not in HA nor in OpenWRT.
HA was updated and OpenWRT was updated (some individual packages, not a major update).
Anyone an idea where to start?
