I don't know if anybody else has had this
Problem or will incur it.
We bought a TV box from UK 2 or 3 years ago,
A couple of months ago we lost use of it ,it would not
Download UK TV now app etc,
After a bit of messing around mainly by my 13 year old son,
We bought a wi fi spreader ,set it up , plugged it in with a ethnet
Cable straight to TV box ,now it's all up and running.
Wi fi spreaders vary in price ,we looked on line at media market

And there are 72 euros.
Amazon were 30 euros.
Luckily I got mine locally 32 euros ,namely because of
Football on Friday night ,hence rapido.
Hope this is of help to anyone who has this problem
I must point out that our router is in one of the bedrooms
And TV is in the lounge ,hence the need for a wi fi spreader .
