My Virgin broadband has been rock solid for years until two weeks into lockdown so about mid-April. The Superhub is in modem mode with a Draytek router. I started to experience packet loss and high latency a couple of times an hour. Twenty or thirty seconds and then back to normal. Skype calls would sound robotic and then drop entirely. Whenever I ran Speedtests, it was coming back 370Mb down and 36Mb up. I set up a ThinkBroadband BQM which confirmed how bad it was.
I called support and was sent another Superhub but it performed identically.
Last night I switched the hub to router mode which isn't ideal as all my traffic is now double NAT'd. However, it worked! No missed pings or response times in the high hundreds of milliseconds.
I'm currently thinking that there was an update to the Superhub that has 'broken' modem mode. Nothing else has changed on my network.
Can anybody confirm this or shed any light on the situation?
Thanks for coming back to us and apologies for the delayed reply. I can see there is an issue affecting the services, fault reference F008321553. I have checked the estimated fix date and it's today at 2pm
