Hello.
Forgive me I am a layman and I do not know if the description is enough for you, so I am asking for a large dose of forgiveness. On the floor at the parents' stand is the TP-LINK TD-W8950N router, a stationary computer is connected to it. On the ground floor for Sharp tv I bought a box MXQ PRO 4K to tune the TV a little. Unfortunately, only the browser, facebook works, but in general it often loses connection in wi-fi and there is no option to use e.g. YouTube etc. I conclude that the signal in the place where the TV stands is too weak. I will add that I cannot move the router upstairs to another place, just like a TV on the ground floor. The diagonal distance from the router and box is not large, maybe 10 meters, but a ceiling and two walls. I would like to strengthen the signal and I wonder how to do it at a low cost so that the box fulfills its role and that the cash register on it is not thrown down the drain. I am asking for advice - not in a complicated language
, and so you know for the total rookie. I was thinking of buying an amplifier for the TP-LINK TL-WA854RE socket.
I will add that wifi (Orange- via tel. Landline) is generally miserable and his parents have the highest power on the connection up to 10 mega, although it probably never is there.
