Very slow speed and hub constantly resets itself

For some time I have experienced very slow speeds and the hub 2 regularly resets itself causing 3 or 4 minute drop outs.  When I first had this service it was excellent but it has gone downhill severely over the intervening period.

i have vivid 200.  I’d appreciate some advice and assistance in resolving this - the speed appears to improve when the hub resets itself - typically every few days but occasionally multiple times in a day.

Re: Very slow speed and hub constantly resets itself

Your stats are fine, but unfortunately the logs are showing a few reboots, but may be manual reboots as there is nothing in the logs showing the local circuit dropping. This maybe due to the logs not covering a long enough timespan.

The SH2 can be a bit flaky, so I would reset the Hub back to Factory settings  just to refresh the firmware to clear any minor corruptions.

I would start a Broadband Quality Monitor to check if the local circuit is dropping. You will need to enable Respond to ICMP Timeout Echo Requests in the Advanced Settings > Tools > Ping section of the Hub's GUI.

Re: Very slow speed and hub constantly resets itself

OK thanks - I'll try that.  I have not manually rebooted my hub for about 6 months so any reboots are all carried out by the hub itself
