I have a really weird problem with this TL-PA8010 PowerLine kit... For the record both adapters are correctly paired, with solid green LEDs.
As soon as I connect either device to the Ethernet port, my PC acts weird then completely hangs, followed with an BSOD on Windows 10 or a hard lock on KDE Neon (numlock LED blinking, I assume that's a kernel panic).
Now this might look like a PC-side problem and therefore, the wrong forum to ask. But I assure you it's not. Right now with the same NIC I'm connected to an Archer X10, and I tested with every network cable, every other router & device I could get my hands on (including a spare Archer C20 I had lying around). Not a single one gave any problem except the ones in this kit... So I think my PC is ruled out as the culprit.
But then, the weirdest thing is that my laptop's NIC work fine with either adapter, with acceptable speeds.
I'm REALLY scratching my head here. What could possibly go wrong with a PowerLine setup to cause this? I even contacted the construction firm (this is a 3yr old apartment) to have my electrical wiring checked, they said all is OK. Warranty is sadly out of the question b/c this kit was bought by a friend in Europe while living there years ago, then gifted to me in South America where I live.
My NIC is an integrated Atheros AR8131 PCIe GbE... I don't think there's a known incompatibility there?
