Did a factory reset on my two tuner tablo yesterday. I was hoping it would stabilize some things as it has been a while. I wanted to remove all possibility that tablo would be using wifi, as I had originally set it up, and only using ethernet as I had noticed that after I plugged it into the router that I still saw the tablo connected to my main router via ethernet as a device registered there.
After the factory reset I configured that the tablo was communicating via ethernet and rescanned channels and finished the reset. I cleared my cache in my linksys app and refreshed the devices list and tablo was gone…great. About 10 minutes later I checked devices again and “poof” it was back connected to the main router via wifi.
I thought factory resetting cleared any settings including wifi settings.
Are you sure you are not seeing it due to wireless card having a DHCP Lease?
Can you ping the IP that shows for the wireless card? also the NIC IP address?
Edit: my Gen4 Tablo is connected by hardwired and it does not show up on my wireless at all.
