Hub 3 intermittently losing connection / restarting

Hi, 

For the past week or so my hub 3 has been randomly dropping connection or restarting (not sure how to tell the difference).  I have done a factory reset and swapped it from router mode to modem only mode.

I started to write down the times it happened while it was in use:

Sat  - 20:30, 20:59, 21:08, 21:49

Sun - 21:45, 22:57

I have started running BQM and this is the graph so far:

The status of the router is below:

Re: Hub 3 intermittently losing connection / restarting

How are you connecting your device, Wi-Fi or ethernet cable ?

Your Hub stats are OK, the Downstream Power Levels are quite high but still well within spenc.

Apart from the full height red band late last night your BQM is looking as good as it can be.

Keep a record of the drop outs to see if they align with anomalies on the BQM.

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 the area. Be aware that it isn't a manned line.

Re: Hub 3 intermittently losing connection / restarting

I have a windows 10 pc connected via ethernet cable, and than various other devices connected via wifi. Everything drops out at the same time.

 

It is reassuring to know everything looks fine. The connection is working perfectly apart from these dropouts.

 

I will leave the BQM running and keep writing down the dropout times.

 

Thanks.

Re: Hub 3 intermittently losing connection / restarting

Hey there DrMKLewis,

 

I've tried to take a quick look at your network details but the Hub seems to be offline or I may be looking at the wrong account so haven't been able to post back my findings. Please do keep monitoring your connection and let us know if you experience further connection issues.

 

Thanks,

 

Lisa
