Hi. It's going to be long, but I'll try to explain everything in details

I'm going to try to ask question here instead of calling because I can see there is a lot of people here with knowledge much better than people working in call centre, and I'm getting slowly tired already and close to just cancel contract and move on somewhere else.

Year of no problem with Virgin (over 10 years customer always happy). End of last year I had some problems with router dropping connections, Virgin said it was some of their problem and they working on it. The problem was sorted and for a few weeks it was OK.

From February (I know I live with is way too long, but I tried to give Virgin time hoping it's again problem on their side and going to be fixed) I have connection being constantly dropped many times a day for 20-30 seconds and coming back. It's getting worst and be annoying more and more.

I have constant errors on router - tried normal and modem mode as well - it makes no difference at all. I checked cables and restart it 100's times, so please don't tell me to do it again. Makes no difference, same problem all time. I'll post you all details under, hoping you can get something from it and give me some help and advice.

Can this be problem with router, cable (I dont have different one to check it), or its just Virgin problems in my area all the time.

Regards

Lukasz

See this thread re the known issue affe cting most VM customers

https://community.virginmedia.com/t5/Networking-and-WiFi/VM-CORE-NETWORK-FAILURE-URGANT/td-p/4986440...

Your Up power levels are all high and there are too many errors - so can you start from a "clean sheet"
___________________________

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

See if the Up powers have dropped from 51dBMv - which is at the top of the recommended range

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's & TP-Link Archer C64 WAP. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

I did restart router and got last 14 hours of data. Same things same errors no difference. During day internet is just unusable for anything which rely on stability. If this is well know problem affecting people for weeks and Virgin do nothing why whats the point of paying for this crap.

Hi luk_neo

 

Welcome to the Community and thank you for posting.

I am very sorry to hear you have been experiencing issues with your internet dropping out. 

I have taken a look from our side and can confirm that there has have been no error detected on the equipment and the signals are running within specification. 

With this being the case, we would need to look in to other possible causes for the interruptions with the service. 

Can you please check that the cables leading to the Hub are secure and without damage? Also, can you please let us know if you are using any third party equipment with the service? 

Thank you 

 

Nat

I only use Virgin hub at this moment no other equipment, have 2 computers connected by cable and 2 phones and tablet by Wi-Fi.

I found different new cable which I got from years ago delivered with Virgin router and replace my old cable. Everything between box on wall and router is nice secured and cable is new. After another 24h there is almost no difference on new cable compare to last 2 months.

Same errors, same results on BQM, everything is almost same like for last months.

This is definitely problem with Virgin Media equipment, and if it isn't isolated problem to me only and affect a lot of people on forum, somebody should tell us WHAT and WHEN will be done with this. So many post on this forum with almost similar issues. And if Virgin Media can't fix it, we should be told about it, so we can move somewhere else.

Service which I have for last 2 months is not worth to have for free and paying for it is just pure masochism.

@luk_neo you are indeed, along with everyone else, suffering from an oddball issue which seems to last for a couple of hours every day - it’s that odd looking  hump in the BQM graph.

However you also have a general connectivity issue, I suspect you’ll find a bad cable joint somewhere between your hub and the street cabinet. Realistically you’ll need a technician visit to hunt it down and fix.

Hi luk_neo,

Thank you for reaching back out and for checking the internal cable, I was able to find you on our system with the details we have for you and can see some short term issues, can you please try a pin reset, push a pin/ paper clip in the reset hole at the back of the Router, push and hold in for a timed 1 Minute, do not reboot during or after, allow 15 Minutes to settle.

Regards

Paul.
