Hub3 dropping internet and unreachable

Kenshin

Hello,

For the past few days our hub 3, which we've had now for a few months, has been dropping the internet connection in the middle of the day with no seeming regularity. Last time it did it I went down and saw it was flashing green, then solid green, then back to magenta (red)?
We run the hub3 in modem mode. Our own router and switch continue to work just fine but when the internet drops off so does the hub. What I mean is that it is no longer reachable at 192.168.100.1 until 2-3 mins later when it has seemingly rebooted. I suspect this is due to overheating what with the heatwave.

BQM above.
Do see a lot of activity in the modem log:

Seems to last longer if you turn it off and back on, but still its not exactly reliable right now. Not had any real issues with it until the hot weather turned up.

Thoughts appreciated.

Could be a local issue, check with:

Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level.

There are 10 types of people: those who understand binary and those who don't and F people out of 10 who do not understand hexadecimal c1a2a285948293859940d9a49385a2

According to the robot lady there is an intermittent fault, of course as its intermittently failing...

Got the text with link to check after 23 hours.

Hi Kenshin,

Thank you for reaching back out and for the update, how are things today, has the area issue now been resolved.

Regards

Paul.

Hi Paul,

Curiously everything seems to have sorted itself since I went through the phone and "checks" were done.

Will be interesting to see what happens over the weekend but for now all good!

Hi Kenshin,

Thank you for your update and letting us know you have seen improvements. 

How have things been over the weekend please?

 

Nat

Hi Natalie,

It was ok over the weekend.

However, today it went down for 5 hours. A factory reset again got it working eventually but I now think the hub itself is at fault rather than simply overheating. Phone earlier and the lady on the phone was unable to reach the hub to perform any checks and a technician is booked in to visit tomorrow, hopefully to swap out the superhub.

Thank you for getting back to us Kenshin. 

Our apologies for the issues today, please do let us know how the visit goes and if you require any further assistance. 

Thanks 

 

Nat

Visit was earlier than anticipated but not a problem. The issue was down to power levels being affected by a frankly ancient cable splitter (15+ years old) in the brown box outside the house.

After swapping it out and checking the levels all was well again, nice easy fix.
