Best powerline equipment when GFCI is part of the picture?

[oldserverguy]

So far I've tried a Trendnet TPL-430A and a TP-Link WPA 7617. I 500Mbps service but most results for my office in the garage which by code has GFCIs is 20/6. Sometimes more - sometimes less. One thing both have in common is that the "remote" device does have a ground which implies that neutral/ground isn't used - which I think would be the best.
I thought a D-Link DHP701AV might work but the firmware hasn't been updated for years and I can't buy new ones on the big "A".

PLA is a crapshoot. Yours is more crappy than some (and less crappy than others). It is not uncommon for a garage to be wired with a shared neutral which could be causing some issues. It is unlikely different brands will yield much different result, which is why I'd suggest looking into the P2P wireless.

I installed 4 of Trendnet AV2 adapters TPL-422E. They are about 4 times faster than my old Netgear powerline adapters. Keeping these and getting a set of 2 (TPL-422E2K) for my other network - yes we have 2 networks. 1 is on a VPN and 1 straight out - 1 for secure traffic like my computers and 1 for visitors. The straight is also used for the few websites that don't allow VPN traffic - mostly Etailers.

The adapters don't have WiFi like my former products so I'm just buying inexpensive dual band routers for my office and the courtyard. Getting the 4 setup was time consuming - I ditched the included "user guide" and downloaded the full manual which has much more information. Even with that took longer than I expected. One interesting thing was different from my previous product was that every adapter is identical.

80/36 is still pretty lousy but if it works for you, then sounds like you're good.
