Recently, starting 4 days ago, I've been getting lag spikes on my internet causing me to lag when playing games making then feel unplayable when playing. I'm watching a Livestream it'll buffer. I have tried a lot of fixes on the equipment that I have at my home and have come to the conclusion of it being a problem with a nearby virgin hub.
I'm sorry to read that you are having issues with your broadband connection.
From checking your connection, the line and hub have come back as fine. There are no faults reported and the network segment is running stable, which is great.
Do you notice an issue on all devices or just on the Xbox/PS4?
Does this happen at certain times of the day?
Are you able to create a Broadband Quality Monitor please as this will check the performance of the connection? If you do set up the BQM make sure that you go into your router settings > Advanced Settings > Ping > and tick Respond to ICMP echo requests sent to WAN IP.
