|TP-LINK produce a range of products. As you have not given the name of the device my guess, from your description, is that you mean their "Power-line Adapters". In which case one possibility is to obtain an extra one, then replace each one in turn to see if one of them has failed.|
Otherwise, if the same products are working OK for other computers then it could be your TV settings have changed. Hard to say without more detail but the trick is to use adapter substitution, noting what works and what doesn't, to determine where the trouble lies.
I am using three inexpensive PowerLine type products (one at the router, one for a PC and one for a TV) and they have been most satisfactory.
Always pop back and let us know the outcome - thanks
