For the past 3 weeks I have been experiencing packet loss. It doesn't happen at peak times but can happen at any time. On top of this, my download speed throttles to around 80mps but upload remains normal, around 30mps.
I have had an engineer and multiple technicians here and the router replaced (although it was a 4 year old refurb).
I've had the cable replaced from the road to my home as well as all the technology in the box in the road replaced to no avail.
The last time I had a technician out they changed the bands at which the WiFi operates on and it worked for 4 days until I rebooted it, and now I'm back to square one.
