How normal is it for a TP-Link powerline homeplug to fail

[Adsibob]

I’ve had a setup where I run internet from a Ubiquiti Dream router to a PoE Switch via a pair of TP-Link powerline adaptors. The PoE switch then provides data and power to two Ring PoE security cameras.

It’s worked really well for the best part of a year. I have Ubiquiti surge protectors interrupting each PoE connection (ie between the PoE camera and the Switch) just for belt and braces protection.

A couple days ago both of these Ring cameras went offline. My other PoE cameras were fine although they are plugged into the Ubiquiti Dream Router directly.

Initially I thought the issue was the cameras themselves, as the TP-Link powerline adaptor had normal indicator lights and I just suspected Ring over a reliable brand like TP-Link. Tried resetting and reinstalling them, but that failed. It soon became clear there is a fault with the TP-Link as leaving it on causes the consumer unit to trip the only other appliance plugged in on that socket pair (a tumble drier).

So this means the TP-Link has died after 10-11 months of continuous use. Annoyingly I think it’s out of warranty, as I bought it a while back. Just wondering whether to replace with another Tp-Link adaptor, or go for a more reliable brand.
