BQM periods of 100% packet loss and high latency

Hi,

I've never had a very good, stable or reliable connection with VM, recently had an engineer out to sort out low power levels however lately the connection has been terrible with multiple drops in connectivity throughout the day.  I have a Hub 3.

Whilst trying to work from home we experience frequent drops in connection, yes its WiFI not wired using a wired connection is not practical.  We frequently experience drops for a period a couple of minutes where the WiFI signal is reported as strong but multiple device experience no internet connectivity or extremely slow connectivity.  Then magically full speed returns after a short blip.

I see the same behaviour on my WiFi extender too, it reports a very string WiFI signal with the Hub but no internet connectivity.  I don't believe its due to the WiFi signal.

I'd previously set up a BQM and pretty much every day there are large periods of time where there is 100% packet loss and huge latency spikes.  

Here's the BQM from Friday 13th which was a particularly bad day for connectivity:

and here's a view over the weekend too:
https://www.thinkbroadband.com/broadband/monitoring/quality/share/c5c8baa7c283cc50d0495972a9af2fa743... 

The reliability of the connection is becoming really annoying, perhaps I'm paranoid but it seems to get worse in bad weather.

Any suggestions would be appreciated.

Thanks

Steve

Re: BQM periods of 100% packet loss and high latency

Here's some more BQM's showing the blocks of packet loss

https://www.thinkbroadband.com/broadband/monitoring/quality/share/a31d2663adc9948f1156a9b7890863482f... 

https://www.thinkbroadband.com/broadband/monitoring/quality/share/e8e20addc42bbb4f750a544fde51d67e57... 

What's the issue with the frequent blocks of packet loss?  These seem to coincide with poor or dropped connectivity.

Really frustrated with the poor reliability of this service.

Re: BQM periods of 100% packet loss and high latency

Today my BQM is showing 100% packet loss for the entire day.  My IP hasn't changed.

Re: BQM periods of 100% packet loss and high latency

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting your district. Be aware that it isn't a manned line.

Go round all the accessible internal and external co-ax connections and ensure that they are finger tight.

If everything is OK, can you log into the Hub Settings and set your Firewall up to the same as below ...

Hub-3-Firewall

Has your connection been of the entire day?

If not just reboot the hub as its prone to dropping ICMP requests for no reason.

Re: BQM periods of 100% packet loss and high latency

The connection is up, although continues to suffer drop outs at points through the day (please see the first post) but for the last few days the BQM is showing as completely red.

All connections are tight, there are no reported local issues and the firewall is configured correctly.

Its just an unreliable service.

Re: BQM periods of 100% packet loss and high latency

Again the red blocks on the BQM is the hub just being dumb - reboot it and it will start reporting again.

Any advice regarding the constant drops in connection?
