New WiFi installation not worked

[Indie68]

Someone came to switch over to full fibre which they did and ever since they've done that the Wi-Fi is absolutely terrible that either doesn't work or it's intermittent. The signal is very weak and it no longer works in every part of the house plus the installation is incredibly bad new wires everywhere all over the house very messy very poor and I would like it to be put back to the way it was

While you can try to get the installation technique reviewed, it's not possible to revert to a copper circuit once full-fibre is in place: that would be going from the 21st to the 19th century.
