Extremely unreliable and laggy Internet for ~1 month now

Tuning in

Hey, I have been experiencing extreme lag almost all day but especially from around 3pm onwards, All devices wired and wireless, usually all evening. Have done all the usual cable checks etc. Can't seem to get an idea of what is happening myself from the router or anything like that. Virgin broadband checker says there's no issues in my area but when I click still experiencing issues I get given the: "Looks like there’s an intermittent signal issue in your area". It has said this for weeks every time I check with no status changing. Will post router stats and BQM below, seem to be getting lots of packet loss and huge spikes, the internet doesn't seem to drop but is really quite unusable a lot of the time, please help

Most days look very similar to these graphs:

Call it in as a fault. Your downstream power levels are far too low and you have lots of post RS errors on some of the downstream channels. 

I'm not a Very Insightful Person (just a little bit, sometimes). I don't work for Virgin Media (but then nor do any of the offshore customer service agents).

First thing to do, though, is to check that your coax cable into the Hub is tightly screwed in.  Let us know.

Those power levels are too low for any realistic broadband access to operate.

Tje Forum Team will arrange a technician when you’ve confirm,ed that the coax cable is tightly screwed in (also at any splitter that feeds your Hub).

Tuning in

try putting the router into modem only mode.

This suggestion will not correct the power levels.

Unless you have a 12 - 15dB attenuator that can be removed an engineer is required.

It might be worth a call to 0800 561 0061 to see if this large power anomaly is a known fault for your street.

Yeah all cables seem fine to me, I had a power level issue last year too where the technician removed my attenuator and said that the connection out on the street was corroded to pieces so he replaced that so not sure why its gone like this again so soon. Guess I will call it in after the weekend or hopefully the forum team get around to it in here. Cheers all.

Thanks for reaching out to us @Dan240v, and welcome back to our Community Forums!

Sorry to see the fault you're currently experiencing.

I've been able to look into the local area for any outages present, but there doesn't appear to be any currently at play.

When then running a flow on your router, our diagnostics on your home network and router have not found any issues that could account for connection drop-outs. 

This means that the issues are most likely due to the equipment being used in the home.

All of the available checks have been performed on our network, however, you can also view the service status to keep tabs on any outage that do come into platy in your area

Additionally, it is beneficial to reboot both your Hub and devices occasionally to help maintain a healthy network connection



Alessandro Volta

It wouldn't half be useful if the Forum Team paid attention to the evidence that the OP provided.

The specific first thing I would want to read is that the power levels are all in range.  That would pay respect to the stats you've presented.

As for rebooting your devices - load of nonsense unless the devices had very bad software, which the hub doesn't in this sense.

Seph - ( DEFROCKED - My advice is at your risk)

This is a bit of a useless reply. There cant be an issue with all my devices and equipment at the same time, unless of course its Virgin router somehow causing it, which it isnt. These downstream power levels are actually worse than last year where I had similar issues.. in which someone was sent out to fix.
