Hi @AndyP ---- Thank you for touching base with me and providing the requested feedback. Appreciated.
Moving forward, I have sent you a PM regarding the time remaining on your trial period with Roon. Secondly, I am going to be touching base with the team to get some more feedback on this issue you are experiencing with your Wifi.
In the meantime, I would like to recommend the following tests to see if we can trigger a change in behavior with your setup. Please see below.
Test# 1 - Does your Wifi drop with just the TPLINK TD 8840 T modem router in play with the mentioned Wifi transmitter and Devolo DLAN devices temporarily disabled?
Test# 2 - Does your Wifi drop with the TPLINK TD 8840 T and TPLINK TLwWR08N wifi transmitter in play with the Devolo DLAN devices temporarily disabled?
