Hi

I recently purchased this kit. At first setup the powerline seemed to work (i did not use it for long time, but i was online in the plug for long duration). I then did a firmware upgrade and reset in order to get them working with onemesh and my MR600 Archer (stil not succeeded thou). But after this upgrade the powerline network seems to be faulty. I can connect most of the time (i paired with buttons or with the tpplc utility) but after few minutes they disconnects. 

When they are connected they have poor connection, with few peaks to 100-300 mbps. (before firmware is was stable on 300 mbps)

I have used the same outlet as before when it worked. and i have used new outlets close to each other. I have no big power hungry machines nearby.

I upgraded the firmware on both devices in the kit. the issues started after upgrading the wpa8631p.

Any good ideas and advices.
