I have a subscription to Smart DNS proxy and have no trouble accessing UK content on my devices here in Spain.

However I want to watch BBC iPlayer content on my Samsung smart TV. The BBC iPlayer refuses to play through the browser on my TV, but works perfectly well on my laptop. At the moment I have a workaround by having the iPlayer content through my laptop via an HDMI cable to the TV. The downside is that the laptop has to work through the wireless wifi and so is the picture on the TV is not as sharp. When I plug an ethernet cable from the router to the laptop, the iplayer does not work as I cannot alter the DNS settings in the router.

My question is, can I buy my own router, one which I can alter the DNS settings, and connect it to the original router so that I can have a direct internet feed to my laptop to sharpen up the feed to the TV?
