Wifi dropping ever since the blackout the other day

[jovshh]

Ever since the fault the other day with sky across the country, my WIFI has been cutting in and out very often. I will be trying to download something and my speeds go from 8 MB/s to 8 Byte/s, It's really been getting on my nerves as I've rebooted the sky hub multiple times, even tried to move the WIFI box or reset my connections. It's been especially bad on my 5ghz connection to the point where I can't even watch YouTube videos without buffering. I've done plenty of googling and attempts of looking for people with similar issues, yet when I've tried all of the ways to "fix" it, nothing has worked. Here's a screenshot of the Sky Hub statistics.

Have you done a factory reset on your hub by holding the reset button down for 30 seconds?

[jovshh]

Yeah I have, multiple times. It mostly happens one the 5ghz connection, randomly disconnecting and losing all internet

HMm that is odd as your rotuer stats dont show any problems. Do you use any boosters/extenders at all?
