Model : I am interested in the above powerline set up. However, I only ever see it for sale as a kit. Is it actually possible to buy extra extenders?

I emailed sales the same question and was told they were only available as a kit but would be releasing a compatible wireless adapter in the uk shortly. I don't know how long shortly is but I have 3 spare ethernet only adapters after having to purchase 4 full kits :-(

Single TL-WPA4220 is available.

And how would that be useful on an AV1200 network?
