As the subject says, I have 8 Powerline adapters. 4 of them are WPA9020 (v1) and 4 are WPA9020P (v4). Generally I have some success, but for the second time today, a number of the adapters have seceded from the network and have formed their own network (with the same name). Today my network became 2 - one was a network of 3 devices and a second was a network of 5 devices (as seen in the TPLink powerline utility). Both times this has happened, the only way to fix it has been to factory reset every device and form a new network. Obviously this is a problem since the devices connected to the network not containing the unit connected to my internet router lose internet connectivity. Sometimes devices seem to enter/leave/enter one of the networks as they flip/flop back and forth making the problem especially irritating.
Things I've looked at:
-I checked the web site and it suggests that this model should support up to 16 so I don't think it's the number of powerline adapters.
-They are all 2Gb adapters so I can't imagine that it's any kind of old/new problem (backwards compat is listed for the 4 older adapters)
-I updated the 4 older adapters to the latest firmware, the newer 4 already had the latest (and only) firmware version installed.
Is there anything else I can/should be doing, any data I should capture to get to the bottom of why this is happening?
