Good plan, Rick. By the way, I've used TP Link and BT AV600 adapters at home are they are fine and fully interoperate. They even come with patch cables, from memory. Whilst the ethernet ports on these AV600 adapters are Fast Ethernet (100Mbps), of course the throughput from the Samsung is the same standard so you won't gain anything by going for AV1000 adapters with Gigabit ports as far as TV connection is concerned. The price differential is in the order of £10 - £20 for the TP Link AV1000 / Gigabit Powerline starter set on Amazon which is a bit more future-proof and will provide backbone speeds from your router directly to the mains at around 500-700Mbps. Useful if you decide to connect other high-speed kit to your home network. Whatever you decide, should you find that the throughput to the TV is around 65Mbps using the cables supplied with the adapters, then - in my experience at least - upgrading to higher quality (e.g Cat5e or Cat6) increases the speed to around 90Mbps.
For what it's worth, I pinged Samsung on support "chat" and suggested that they address this shortcoming over the next year or so - it's a bit mad that both networking technologies are so out of date - if they even fixed one, that would be quite significant. I'd be quite annoyed if I'd spent over £1k on a new TV. Fortunately it was under £400 in my case 😉
