possible intermittent fault ?

[jaberwok]

Download speeds have seemed slow for several weeks. I tested today between 13:00 and 15:00 and got results varying between 67 and 160 Mbps.

M200:  Windows 7 Ultimate: Super Hub 3

Software Version "V1.01.35"
Hardware Version 3.11

Lots of errors - Error Number Error Description

What does this mean?

[jaberwok]

I have now.

D/l speeds 45.4 and 45.2 one minute apart.

43.5 and 45.3 with original cable.

If that is with the Hub in modem mode and a computer in safe+networking mode and on a new ethernet cable using different browsers... then it beats me 🙂

Hopefully someone will have other ideas or VM can investigate - as you are not reaching the minimum guaranteed and if it continues you will be free to exit your contract with no £ penalty.

See what they have to say one here

[jaberwok]

Well, thanks for trying.

I've just d/loaded the current version of MS Edge and that gives slightly lower results but with a massive latency of around 35ms.

I've also ruled out anti-virus and VPN as sources of problems and all three computers, connected via ethernet, are painfully slow. I don't see how it can be anything but the hub.

All VM b/band users I know have hubs at least two generations later than mine so I'm waiting (but not holding my breath) for the promised replacement hub.

Ciao.

I just noticed that you said earlier that you had "no connectivity" when it was in modem mode - I just remembered that on the SH2 when you go to modem mode - only 1 port on the SH2 remains active (the bottom one I think). Worth trying again in case you plugged your device into the wrong port and didnt try them all.

Would also be interesting if you can "borrow" a wifi router - one with GB ethernet ports and try that and see if it helps. Or a £40-50 punt for the TP-Link Archer C6. One thing is for sure.... it will be a quantum leap better for routing and wifi than the SH2 - and also the same over Hub3 or Hub4. And from Amazon you can always return it F.O.C. if it doesnt help.

[jaberwok]

Yeah, bottom port only - that's the one I used.

I just used Samknows again and got 45.2 Mbps download speed ; I then tried one of the other pcs and got an identical result.

The first point at which the two have a common connection is in the hub.

I see it as VM's responsibility and I don't see why I should buy other equipment. Bear in mind that this setup has been working well for several years - ever since the SH2 was current, in fact. 🙂

Thank you for trying.

Hi Jaberwok, 

Thanks for your post.

I am sorry you are having intermittent issues, I can see you have been in touch for a hub replacement but nothing has been put through. Would you want a hub to upgrade to the hub 3 ?

[jaberwok]

Hi Zoie.

Thanks for the reply.

I have been assured that the replacement hub (SH3) has now been ordered and should be delivered on Tuesday next.

Hi jaberwok

Thanks for coming back to us. I can see this scheduled delivery. This can be tracked here 

Let us know how the visit goes

Kind regards,

[jaberwok]

Well, it arrived on Wednesday afternoon. Someone needs reminding that dispatch is not the same thing as delivery.

On Wednesday morning I briefly got d/l speeds of 114 and 104 Mbps but then it went back to 45.2 and 45.0.

After installing the replacement hub, I got speeds of 41.0 and 39.0. Testing on another pc gave 36.8.

Now, a few hours after the re-installation and rebooting, the speed is 45.3. Apparently I have downstream connectivity only.

The Virgin Media web-page test, unusually, actually says that there is a problem. It says "This issue is caused by interference on the cabling coming into your home" so, now what? Any advice would be welcome. 

[jaberwok]

BTW, ironically, Wi-Fi is fine.

Did you know - the beautiful, shiny installation guide for the SH3 mentions ethernet just once - effectively saying "when all else fails, connect via ethernet to go online to look for help in getting Wi-Fi working".
