I would like to know whether is it possible for Powerline networking causes erratic router behavior. Could there be any noise emitted from the electrical wiring of the house, and picked up by the router's wireless antenna? Or could it be possible that the noise affects the router (or other device) behavior via electrical supply?
The erratic behaviors I have encountered before are: - WiFi connection is detected on and off, router's web interface is sometimes accessible if connected. - LAN connection is stated as Unidentified Network on Windows, router's web interface is inaccessible via LAN. - Only partial of the computers connected on the network has working Internet connection. A different set of computers would work when the main LAN cable is connected to a different port on the router.
The same behaviors occurred throughout 4 routers, including a brand new one. However, the issues come and go as well at different time.
If Powerline networking is the cause, how can we detect it effectively?
Your constructive advice is greatly appreciated. Thanks~
