Area 07/Bristol: Speed fallen off a cliff!

Dear all,

Since 27th July my broadband has been terrible. On the M200 Fibre Broadband package. Speed has fallen to basic service levels and failed DNS queries are hovering around the 15% mark. Here is my SamKnows whitebox download trace to show the issue. Note that I was already only receiving 75% of the advertised service since the last engineer visit .

Re: Area 07/Bristol: Speed fallen off a cliff!

Thanks for the suggestion. I checked and there are no faults reported for my area.

In troubleshooting, so far I have moved the SuperHub into router mode, rebooted it, checked the physical connections and cables, and restarted the various boxes connected to the SuperHub.

Re: Area 07/Bristol: Speed fallen off a cliff!

If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

Re: Area 07/Bristol: Speed fallen off a cliff!

After the reboot yesterday, things have gone back to the ~150Mbps I was experiencing in July. Progress 🙂

Thanks for the input everyone!
