Hi,

I have been having this problem for a while.  I have the powerline set up around 10m from the main router and between 2 walls.  I find I am having intermittenet wifi outage when in the vacinity of the powerline adapter.  I have obsereved that devices will migrate to the main wifi despite being very close to the powerline adapter, for example I have a chromecast 30cm away from the powerline but it has preferred the main wifi, despite having camped on the powerline prior to this ? Both are operateing on 2.4GHz, one on channel 1 and the other on channel 13. I dont have any neighbours closer than 30m which wifi.  I occassionally use the powerline in the garage which is 30m from the main wifi and I experience normal operation.  

Any advice ?

Thanks 

John
