Powerline adapter on surge protector.

[sam1275]

Hello everyone, I installed a pair of Netgear AV200 Powerline adapters, one side for modem is through normal power plug, another to my router is through Tripplite UPS on the surge protect socket, the LED are green indicates the link is good, and it works good too.
But after I added another pair works as a different group, one router side on UPS, client side on a plug, I began to experience random packet loss, the LED are also green, but I get a few seconds connection loss every few minutes to hours, randomly.
I know it's hard for them to get through a UPS with surge protection, but I don't want to risking my devices by connecting them directly to wall plug, are there any better idea? The wireless is also too weak to reach. Thank you...

For that application, cheaper surge protectors are generally better.
