View Full Version : General Power Levels for 60Mb
Could someone please tell me the acceptable power levels (down/up) for the new 60Mb service?
thanks
Same as 10 20 30 50 and 100
optimum -3 to +7 down and 35-55 up

Are you having issues with your speed Zee?
I've been having issues since upgrading to 100. I think its our area.

What, the UK? Yeah I hear some VM customers have been having problems there.

Not having any problems with speed, but having problems browsing since being upgraded.
To open a thread on this website, it will freeze/lock up or sometimes take 20-30 seconds to load, of course on Infinity, no issues at all on the same computer(s)
After 2 calls to VM today (the first one totally useless, was unbelievable) im being sent a new superhub, maybe thats the issue, who knows...

So, what is your upstream power? Does it get above 54 dBmv? That would explain long time to load web pages. Then we could go into why that might be the case.

i've had the exact freezing issues when browsing sites. Sometimes the page wont finish loading at all, i'd have to refresh the page.
the max upstream power mine hits is 50
Its currently 44.5 at the moment, dont think i've seen it go above 54. seems strange since the upgrade facing these issues, but speed tests report 62Mb.

Call tech support up and report the issue, as they told me no one else in the area has reported an issue like this.

I spoke to a 100mb tech dude this morning. We tried direct cable connection the modem. He couldn't understand what could have been the issue as the power levels and everything was in order. Got an engineer coming tomorrow to do a repull and re-wire my house.
I also posted this issue on the community.virginmedia.com forum

that may be a waste of time then since im facing the same problem as you, let me know how it goes...

I've also been having issues with speed been getting 32-75 sometimes it would start at 90 then go down to 15 by the time the downstream test has completed.
In any case i'll let you know how it goes.

Don't get your hopes up, if there is no snr showing and levels are fine it ain't gonna be the wiring

i've been asked to run a pathping on the community.virginmedia.com website does anyone know how to do this from a Mac?
I called again today due to you having the same problem as me, so i know the issue im facing is not to do with the superhub.
it was a UK call centre this time and he took control of my PC, it was not on my side at all, everything worked perfect, websites loaded perfect and youtube buffered perfectly.
He said there was nothing he could do as it was actually working flawlessly. Now im guessing any minute it will go back to how it was. :/

I'm still waiting on the engineer to turn up. They said between 12-4, i know it's only 15:05 but i get the feeling this guy isn't gonna turn up.

Call up to confirm they are coming, if they dont at least you can say you called to confirm and get a refund for time wasted.

Hmmm...I'm not upgraded from 30meg and I'm in NN10 but I do seem to be experiencing similar browsing problems. Tracerts are normal but the affected sites refuse to load or are extremely slow. Even when I succeed in getting a page to load it is completely unresponsive when clicking a link.
I assumed it was avast playing up but the problem remains, albeit to a much lesser extent, after dumping avast.

Gave them a call. They did confirm that an engineer is on the way today. I asked what the engineer was going to do as the person i spoke to yesterday said i needed a repull. I was told that the engineer that was coming to see me today is not going to do a repull, but check all the cables to determine whether a repull was needed or not.
Will let you know what happens next... Lol

For the last 2 hours or so i haven't really experienced any sort of issues and my speed test has gone up. Im now easily getting 65Mb or even close to 66Mb. Not sure what the config cap is but something seems to have improved. Dont think it will last for long though...

VM dude just came over. Swapped out the super hub. The upstream power dropped to 47.5 from 50.0 with the old modem and everything seems to be alright. He did say let the "modem set for 48 hours" and the speeds should be back to normal.
Just ran a speed test and this is what im getting...

I'll tell you something strange that almost makes a nonsense of all our diagnoses in these cases.
My topology is:
SH --> Router --> 200 AV Poweline --> GS108 Switch --> Wired & Wireless Access Point
All cases are BBMAX speedtest at quiet time of day.
Wired Qosmio Laptop (Dual Core 2.4) Realtek GBE Controller
Latency: 41 ms
Speed: 50 meg
Wired Thinkpad Lenovo T420 Intel i5
Latency: 25 ms
Speed: 48 meg
5 GHz Wifi Ch 36 Thinkpad Lenovo T420 Intel i5
Latency: 15 ms
Speed: 42 meg
2.4 GHz Wifi Ch 1 Thinkpad Lenovo T420 Intel i5
Latency: 15 ms
Speed: 25 meg
The Wireless Access Point is located 12" from the Lenovo and connects to the main router over the wired path.
So, what's with the wireless latency being so much lower than wired? Is there a network card setting I'm missing?
This sort of thing could presumably affect all traceroutes though not the BB ping which is bound to the router.

All the web-based tests use retarded and useless methods for measuring ping anyway, do some actual pings to compare the results.
Sephiroth
22-03-2012, 16:28
You shouldn't be so dismissive.
The consistency of the results using the same piece of software and site makes my analysis valid and thus also the question I posed.
is there a tweak for the network card that affects latency (Vista/W7)?

There are several dozen, knowing which one to use requires some proper testing.
Your results might be consistent, but consistently wrong results still aren't any good. You've seen test results with these web-based flash apps that claim pings of zero ms, you've also seen results showing 40-60ms+ when pinging the actual server with the ping command returns 16. Again, there are so many different variables that the only consistent thing about web-based tests is their inconsistency with actual underlying network conditions.
If you want to diagnose a LAN-based ping problem, best start with the basics - the ping command. Using a web-based flash app adds hundreds of extra steps each with their own behavioural quirks and many added layers of complexity.
I'm still getting this killer lag when browsing the net. Don't know what to do.
same here, again on the phone to virgin media with a replacement superhub, they told me nothing was wrong.
not sure what else i can do. i directed them to this thread to show others in the area are facing the same issues yet still said there was no issues at all with everything they tested on the network.
now what should we do?
If the people experiencing this issue can post in a thread i created on the official forums, it would be more helpful to all of us if they see more than one person in the area is facing the issues with browsing lag.
http://community.virginmedia.com/t5/Up-to-30Mb-broadband/Browsing-websites-slow/m-p/1104459
Still getting the browser lagging here with no one at virgin media, whether India or UK willing to even escalate any fault, so im guessing this issue people are having here will either never be fixed or wont be fixed for a long time in the future?
Just an update for anyone who's been experiencing the lag issues in NW London, after constant phone calls and posts on their forum, i have finally got a fault ticket reference F001953173 i've been told there is no fix for the problem as the ticket has just been created and they are still trying to pin point the issue here.
Finally we are making progress after being told constantly there was no issue.

i've been getting the same issues. the green box on my road is fine.
Is your street box open or damaged?
the ones at the begging of the street 2 of them are open and damaged, wires ripped aswell, but the one closer to my home which im apparently connected to is totally fine and locked.

Might still be the other street boxes because the (thick) coax daisychains to the optical node. And if noise gets into the other street box it gets into the amplifier.
i see. well i explained that to them that they are open and never seem to be bothered, they've been open for years.
I moved the discussion of browsing lag in NW London to a new thread here if anyone is interested: http://www.cableforum.co.uk/board/12/33686809-browser-lag-nw-london.html
also by the way i did report those green boxes on my street again today, i'll check them everytime i pass them to see if they've been locked and not just wrapped with black tape.
