Ethernet over Powerline problems

I purchased a Powerline AV adapter from Linksys around 6 months ago and had perfect plug and play usability in my house. I recently installed a central air conditioning unit in the house and now I am not getting transmission of the internet signal through the adapters. This problem continued for a few days, then I had one day where it magically started working again and it has gone back to not working since. Please help!

The one thing I know about air con is that a neighbour's unit used to make my lights dim momentarily as it started -- so lots of power being drawn.

I suspect that the motor unit's position in your house wiring may be the issue -- a decent electrician should be able to point to a solution such as a dedicated heavy duty line between the air con and where your supply meets the street.

Another strong possibility is the air con creating noise on your power circuit -- after all the mains supply isn't intended for ethernet piggybacking -- above suggestion or some line-conditioners might be a solution.

Hi There! In the market there is one company that I came across, that would be able to solved this more than a decade inherent problem of Powerline Communication Adapters. Beside they can solved this hiccups on the powerline they also claim that their devices can also protect the electrical equipment from lightning surges.
The main issue with your set up and most PLC Adapter drop in signal or rather throughput will be the inteferences from the compressor noises of the aircond and other devices include the mobile phone charger, laptop charger, TV, vacume cleaner, fridge, waterheater, etc. Typically most of the PLC adapters will tell you that their devices can goes UP~TO 200Mbps and 1000Mbps
