I have a PL network comprising WiFi and non WiFi adapters including one at 600 Mps, 4 at 1200Mps and a camera at 200Mps. This network operates without issue. The router is connected to a 1200Mps adapter. I hoped to increase the speed between the router and my TV by replacing two 1200Mps adapters with two 9020's (2000Mps). However, as soon as I do this I get instability in the network. If you use the tpPLC monitoring utility you can see adapters appearing and disappearing randomly as it refreshes which doesn not happen with the 1200Mps adapters. Anyone had this problem? Any ideas as to what might be the cause and potential solution would be appreciated since TP-Link support don't seem to have a clue! Thanks.
