intermittent signal EH15

[mcissac1]

Hi, having issues with frequent signal drop outs, affecting both laptops and phones, and causing our work VPNs to drop out and video calls to freeze.

When I look at service status for our postcode it shows green - but when I go in and test the hub it says there are intermittent signal issues in our area, This has gone on for months. We're a couple of hundred metres from the cabinet. Please could someone advise whetherer there are plans to resolve this, as it seems to be a known issue? We've done frequent hub resets and it hasn't helped.

Run the FULL test from this site and post the results please.  www.samknows.com/realspeed

Post the power levels, Pre and PostRS errors and network log from the Hub.

Setup a BQM to monitor your circuit www.thinkbroadband.com/ping

Once done we can comment.

Hi, thanks for the response, I set up a BQM yesterday and it can accessed at

Let me know what else you need - please be specific and describe in plain english as this is the first time I have actully logged into the back end of the hub.

[Adduxi · Accepted solution]

 Your realspeed shows 136 to your Hub, but only 16 to your device, so you will need to check this, as the Hub is getting full speed both up and down. (125 Tier?)

Okay, the BQM looks not too bad.  There are too many T3 timeouts on the Upstream channel 1, and too many PostRS errors on the Downstream.  Normally this might indicate noise on the circuit and will need a VM tech to investigate and fix. 

All you can do is check all the connections from the Hub to the outside box are at least "finger" tight and not corroded.  If you wait here a couple of days a VM Mod should pick this up and discuss with you.

Thanks, that's all useful pointers, we're in a coastal area and been told anecdotally that local connections suffering from corrosion. Grateful if VM Mods/tech could get in touch when possible.

Hi @mcissac1 

Thanks for posting and welcome back to the community.

Sorry to hear of any broadband issues.

You do need a tech visit so I'll send you a PM now to assist further.
