On-off-on-off connection after power up

I power the SHUB down each night for several reasons. Some mornings it boots up perfectly, other days it's on-off-on-off for around an hour sometimes. After 2 days with no problems this is the typical situation:

Re: On-off-on-off connection after power up

It is strange that it becomes stable after being on long enough.

If you turn it off now then back on does it go on-off-on-off before being stable?

Hard to tell whats at fault maybe a firmware boot up problem, some type of fault with the super hub or PSU or an issue with the Docsis network on a cold super hub boot up to get going.

Re: On-off-on-off connection after power up

Hi Taf,

 

Those T4s don't look great on the network log. I've checked your connection from here and I can't see anything wrong. The next time you get this on off issue when booting up could you check the network log again and see if the same T4s show up?

Re: On-off-on-off connection after power up

Hi Taf,

 

Thanks for posting the log again. I still can't see anything to cause the T4s so let's get a technician to check the local network and your connection to see what is causing this.

I've just sent you a private message to arrange the best time for this.

Re: On-off-on-off connection after power up

I had a tech out just recently, and he could find no problems. It appears to have cleared over the past couple of days. I'll monitor and post any problems that reappear, as I will not be available to be home for another tech visit for a short while.
