Connection Issue (DHCP?)

Looking for help and advice please

Gigabit package with Hub 5.

Friday afternoon, i unplugged my router and various other bits from the mains for a short while.

When booting back up, the Hub 5 just flashed blue. Checking the hub homepage it said “requesting cm address” in red.

Did the usual troubleshooting, removed the copper, removed Ethernet cables, removed power. Left it, tried again, same thing.

Did the reset, still the same. Repeated cables too, same.

Rang Virgin and had one of the worst experiences I’ve had with them. Had engineer booked for Monday.

I left hub disconnected from everything for a couple hours, then reconnected everything, this time removing the attenuator (or gain I can’t remember which). The hub got an address. 

I refitted the adapter and it stayed working. Cancelled appointment 

Saturday night (around 11-12), I lose internet. I check the hub page and the status is fine, but diagnostics fail.

I reboot the hub, then end up with the same blue light/cm address failure.

As it’s late, I just leave it. 

Around 6-7am, connection restores itself.

Whenever I try the Virgin media status check, it says it can’t find my account.

Whats going on here?

The Power (dBmV) is way too high. It needs to be in a range that is close to zero positive or negative. What is the value of the resistor that is screwed into the cable. It should say something like xxdB forward path attenuator.

Best to get a VM technician to move your cable tap in the street cabinet, as mentioned your Downstream power levels are far too high.  Range is -6 to +10, so yours is over the top.

I'm a Very Insightful Person, I'm here to share knowledge, I don't work for Virgin Media. Learn more

It’s a 3db attenuator. It was installed by Virgin, before my Hub 5.

I doubt its to do with power levels more like a the 10. modem DHCP server not working for your area.

Hi there @Bagz86 

 

Thank you so much for your post and welcome back to the forums, it's great to have you back. 

 

I am so sorry to hear that you have faced this issue, with your service. I have taken a look and I can see there are a few issues on the specs that will require an engineer to take a look. I will be happy to arrange this with you via a Private Message. 

 

I will pop you a PM across now, please keep an eye out for the envelope at the top of your screen alerting you to a new message.
