Real connectivity issues

Last night both myself and my daughter had serious issues with our Broadband. I have had a number weeks of the internet just stoping. I can connect to the wifi and have an Ethernet connection for work, but I keep getting messages saying 'no internet' on the connection, regular buffering and web streaming stopping.

I have re booted the Superhub 3, reset it to factory settings and still the issue remains.

I ahem run a port scanner on it and it shows that it regularly shuts Port 80. This should be open when I am browsing a web page. A HTTP demand should open the port for traffic to and from the web however the hub keeps it firmly closed. 

I have had a succession of hubs from the original nil: Cable Modem (I was a trialist) and this is the worst one I have had. It just seems buggy and inconsistent.

I have been a Cabletel/ntl:/Virginmedia customer for over 20 years and this is the first time I have considered leaving. However I cannot keep working from home if my Teams keeps dropping out!

Any thoughts appreciated.

Re: Real connectivity issues

Power levels are within spec, however you have noise on the circuit, as shown by the huge number of PostRS errors and SYNC failures in the log.

Check all your connections from the Hub to outside and make sure they are all "finger" tight.  Other than this, you will need an engineer to locate the issue and fix it.

Re: Real connectivity issues

Thanks. Yes they are.

Stupid question time. The cables to the hub are alongside a power extension lead. Would there be any issues with signals from this?

I have put the hub on top of a bookcase to try and extend the signals so there is an extension lead.

The original install was 20 plus years ago so there is a possibility the box outside or the inside box may have deteriorated. I will get an engineer call in. 

Anyone know how to do this easily??

Re: Real connectivity issues

The cables are shielded so should be okay.  As for the age of the cables, mine would be of similar vintage and I don't have any issues.  But best to get an engineer to check all out.  Ring VM at 08:00 as the lines get busy very quickly, or wait here for a couple of days for a VM Mod to respond.

Re: Real connectivity issues

Hi bobprice,

 

Thanks for getting in touch! I'm sorry about the problems that you've been having with your connection.

 

I've been able to locate your account using your Forum details. I can see that there are some issues with your Hub, so I've booked an engineer appointment for you. You can find the details of this appointment on your MyVM page.

 

Please let me know if you have any more problems with thus.

 

Thanks,

Laurie

Re: Real connectivity issues

Thanks very much Laurie. They are due tomorrow. I will also ask them to check the box on the outside of the house. It was installed in Cabletel days and more than a few spiders have crawled through it since then !

Re: Real connectivity issues

Sounds a bit spooky to me! Please let me know how everything goes, I'm sure our engineer will be able to sort this for you.
