Volt 1gig speed

[edge82]

Hello,

So I recently had my package changed with the Volt addon due to having an O2 contract phone and figured its free so why not to the 1gb Volt.

Previously I had a hub 3 on the M600 broadband running at speeds of between 550 and 650 mbs per sec down with a 50mbs up but on this Volt 1gb it appears that for the first 10 minutes of either the Modem being rebooted or the lead being disconnected / reconnected I get around 850 - 950mbs which is great but this is for all of 10 - 15 minutes before it drops between 40 - 160mb and stays at that range until a reboot is done and again only maintains a reasonable speed for 10 - 15 minutes again.

This is reflected at both speedtest.net and Samknows speedtest along with downloading anything on say Steam or so forth.

I generally use the hub4 in modem mode and Route the traffic through my Nighthawk x10 R9000 router as I did with my hub3 when on the M600 package using cat6 cables to 1gb cards in my pc's bar of course mobile phones or tablets that use wifi, I've popped the hub4 into router mode and connected my cables directly to this to rule out the Nighthawk X10 Router being at fault. 

My Virgin cable setup is a cable coming in from a virgin socket which then uses a splitter to split off to the Tv and Hub4 , I've tested New cable's and a New Splitter as well as a Direct Connection without the splitter and I also have a secondary Line coming in for a television upstairs so I've also tested this to no avail with the same fault repeating.

The annoying thing is the network log on the hub 4 is most the time blank even when logging in but I'll post my other stats to see if anyone can see if they look off at all.

Thanks

Wayne

There is clearly an issue with your connection:

• Downstream power levels being out of spec on several channels (-6 to +10 is in spec, 0dBmV being optimal).
• Downstream SNR bad on several channels.
• Lots of 'Pre' and 'Post' RS Errors on the 'bad' downstream channels.
• Upstream power levels very high.
• DOCSIS 3.1 channel power level very close to being out of spec.

Thanks for the Response Carl, I'll see if I can get Virgin to send an engineer out.

Hi edge82, 

Thanks for posting and sorry to see you've been experiencing some issues with the speeds.

I've had a look at things from our side, and it does look like we've identified a short-term connectivity issue which may cause intermittent or performance related issues with your connection.
In the vast majority of cases, these types of issues are resolved after 24 hours. If you can please monitor this and if you're still having problems after this time frame please let us know.

Unfortunately even after a turn off (late sunday night) since the information sent over by yourself Alex on saturday, unplugging the cables waiting a couple of minutes and plugging it in and switching it after 10 - 15 minutes drops the download speed to 40mbs per sec.
