Intermittent Connectivity Issues
As the subject says, I'm having intermittent connectivity issues. It happens throughout the day at random times, and connectivity is lost for 5-10 seconds. The major issue is Teams meetings are freezing.
- Set up is a Hub3 with Google WiFi.
- Pings to Google WiFi never timeout. The Virgin Hub and Internet both timeout during the drops.
- I've tried a ping test from the hub but when the internet drops I lose connectivity...
- I've tried the Hub in Modem Mode and no change. I've performed cable checks, restarts, resets... everything.
- I can't get BQM to run as the hub doesn't have an option to allow ICMP traffic.
- I've spoken to Virgin multiple times but am told they see no issues on my connection so there's nothing they can do.
Hoping someone from the Virgin team can pick this up and help. Thanks!

You have 2 issues
1) MS Teams remains the only constantly complained about video conf platform and that has persisted for years.
Avoid Wi-Fi for MS Teams, the extra latency & jitter + half duplex of Wi-Fi does appear to make matters worse.
For our slimline laptops lacking network sockets we have HP USB3 to Gigabit network adaptors.
2) Looking at the VM Hub stats, the Downstream Power levels have a preferred range of -7 to +7 dBmV absolute max of +10 dBmV and in this case the value are all too high.
Should you have a 10dB attenuator on the coax to the VM Hub, but that has been removed ?
If not this is an engineer task to correct the excessive power levels.Downstream bonded channels
