Problems with WiFi on Movistar

Hi All,

I wonder if you can help, we have a villa in tahichi and the main router wasn’t strong enough for the whole villa, I put in some boosters for my parents and it worked fine for a few days, since then not at all only through the hard wire not the WiFi- is there an internet specialist or company that can come and get it all working and advise us how to keep it that way?!

Thanks in advance
