We have UFB atr home, Fritz Box 7490, all firmware up to date etc..
The UFB box and Fritz box are down stairs and in a office but the smart 4K TV and all other wifi devices suffer lag around the house especially upstairs.
So what shall we do? I am really not wanting to run LAN cables all over the house (that what my kids are say) but must be a better way.
Looking at purchasing Asus RT-AC88U?
Or extender / boosters, but i think this may suffer as well?
We really need to boost the wifi strength around the house and remove the streaming lag as much as possible..
