I have 200/10 internet at home, and had been using the AV600 powerline adapter in my office. Typically I'd get 80/10 out of that. I bought a refurbished set of the AV2000 adapters from TP-Link's eBay store, and plugged them in the exact same location today that the AV600 were in. They are SLOWER than my old powerline adapters! I can't get any higher than 57/10 out of them in a speed test. The tpPLC app had a link speed of around 200 with the AV600, and I currently have a connection of 788 between the AV2000. This can't be right. Any ideas?
