Hi,
I joined VM in December, and on Gig 1 service. So far the service has been very good and reliable until the last week. On two occasions there was no internet connectivity, only rebooting the Hub resolved the issue, and on several occasions momentary internet disconnection.
Monday 23/03/2020: Around 9:00 AM service became a bit unusable. Skype was sluggish, dropping connection. At 10:12 received the following errors in the Hub followed by no internet at all. Reboot fixed it.
- 10:12:47 SYNC Timing Synchronization failure - Loss of Sync;
- 10:12:50 Lost MDD Timeout;
- CM-STATUS message sent. Event Type Code: 23;
- Lost MDD Timeout;
- Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;
- Lost MDD Timeout;
- Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;
- MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;
- 10:30 RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;
However, experienced disconnects on several occasions throughout the day.
Wednesday 25/03/2020: No internet at 08:20 AM. Checked Hub logs but nothing there since Monday (previous logs). Reboot fixed the issue
Setup
- Hub 4 in Modem Mode (since December)
- MikroTik router with the firmware dated 28/01/2020 6.46.3
- ASUS AC87U as WiFi access point
- ASUS RT-N66U (Different Sub-net for TV and Media stuff, no WiFi)
- Two switches for different equipment like cctvs, NAS, desktops etc.
Nothing has been changed in the setup since December last year. Below are Hub 4 stats. Can someone please look into it, and advise? Currently Skype, Teams, and online gaming (Fortnite) are affected.
