Virgin Customers: What is your Ping?

was there any charge with this? If not, how did you manage that one? :D Is it gigabit ethernet on your Dlink? I have a D-Link set up as a bridge, but I believe it's only 100Mb ethernet? I could be wrong though...

This would be my third superhub since XMAS. I spoke to an english woman (not an Indian) and she was fantastic. I told her about how bad the wireless is, and also how we have a mediabox in the next room and yet we were only getting 40% +/- 10% signal strength. So, she said she'll be able to send out a wireless modem to hook up through the Ethernet port (I had to disable the wireless on the superhub). A few settings here and there. Sorted.

Oh, yeah, she also mention that the new firmware for the hub will be in mid-July.
 
im on 30mbit in East London and my ping goes from anywhere between 9ms and at peak times 250ms... Its really rubbish TBH and they know it but wont do jack cos its too much money
 
100MB :D

If you want to test your ping, ping something that'd you'd expect to give a low ping like a game server provider.

Obviously you can see my experience is quite good for someone from Scotland, but if I'm honest I don't really feel my ping has ever been as stable as it was back when I had ADSL.

My ping has got a lot better with the new service, but the speed is the problem now :D

You're in West Lothian, so near me... Do you find your Virgin Line alright? No Problems?
 
Can get 100Mb now, but suffer from disconnections (which is a known network fault). Wont upgrade till R28.



Check it out.. near perfect downstream power levels:

Locked QAM256 198 55616000 Kbits/sec 299000000 Hz 0.0 dBmV 38.6 dB Hybrid
Locked QAM256 197 55616000 Kbits/sec 291000000 Hz 0.2 dBmV 39.1 dB Hybrid
Locked QAM256 199 55616000 Kbits/sec 307000000 Hz 0.0 dBmV 39.0 dB Hybrid
Locked QAM256 200 55616000 Kbits/sec 315000000 Hz -0.2 dBmV 39.0 dB Hybrid

Id prefer SNR to be better.

When I first got it installed, my power levels were messed up and I had frequent high pings and disconnects. I called them up, and the next day I had an engineer out who fixed it. Since then, I've gotten pretty much full speeds all the time, though VM have made failed attempts at throttling certain protocols. I've had ping as low as 15, but realistically they're a bit bouncy and sit around 25 on average to UK servers.

I'm a pretty hardcore competitive gamer, so ping is all important to me. If infinity ever becomes available in my area, I'll definitely be checking it out with a mind towards having a better ping. I'm a fairly happy customer overall but it's not like I have a choice either. In any event, I'm one of the lucky ones, those in oversubscribed areas have a horrible time.

Regarding speeds, you won't always see them max out everywhere, and most of the speedtest.net servers will fail at measuring such high speeds. VM will rate limit certain protocols, but this can be bypassed by changing port and using encryption.

For normal browsing, if its slow its probably because their DNS servers are horrible, try some new ones and you'll probably get a better experience.

I'm on 50/5 (just got the upload upgrade last week). I'm in the process of upgrading to 100/10m so we'll see how that goes.

That doesn't fill me with confidence. Care to give me more info? :)

Virgin Engineers are a bunch of lazy slugs, they've been trying to fix a fault for 3 months in the network which on the Upstream. After a while there's too much noise and it kicks the modem off the network.

They still don't know where its coming from even though their own equipment is telling them theres a fault causing T3 timeouts.

Why only near perfect?? Optimum DS power levels for QAM256 is -3dBmV to +7dBmV so you perfectly fine at 0dBmV-ish

Again, it's already fine. VM stipulate 32dB minimum, 35dB+ preferred.
So your SNR is more than double what VM desired, and 4 times the minimum.
 
I'm having some huge slowdowns with my VM line lately, is it possible to know if I'm being throttled? I don't download anything but there are 3 computers connected to the router and some video streaming so I may be pushing it over the limit.

I figured (after talking to VM engineers) ideal power level will be 0db on downstream, so the CMTS system aren't sending any extra power to your modem. Less power used, less noise being amplified so your meeting the DOCSIS 3 standard rather then a minor an offset of the standard.

Just reminiscing my old SNR which was 42db. Then it gradually crept down to the 39db which it is today.

The above is what my superhub shows me, on 100Mb where I get varied speeds from 30mb to 97mb.

I don't understand what it means so maybe someone can help?
 
If your on QAM64 modulation, your DS power is too high.
It should either be -10 to 0, or -7 to +3 depending on the network config.

If it's -10 to 0, you are getting more than 4x the max power your supehub should be getting whereas on -7 to +3 you are getting more than double the maximum signal.

I'd recommend popping on to the bay and buying a a cheap f type forward path attenuator (-6dB should do you) and screw that inline with your signal cable and see if that helps. Mine was about the 7dB over when it was installed so I had a -10dB attenutator fitted. Now it's dropped a little and I've swapped it to a -6dB.

Thanks, I'll have a look into that...:)

EDIT:

Thanks to my brother who happened to have an attenuator floating about at work, I now get:

Locked QAM64 90 41712000 Kbits/sec 442250000 Hz 1.4 dBmV 36.0 dB Hybrid

Locked QAM64 89 41712000 Kbits/sec 434250000 Hz 1.0 dBmV 36.0 dB Hybrid

Locked QAM64 91 41712000 Kbits/sec 450250000 Hz 1.4 dBmV 35.7 dB Hybrid

Locked QAM64 92 41712000 Kbits/sec 458250000 Hz 1.5 dBmV 35.8 dB Hybrid

and the download speeds are now stable and constantly about 85Mb. Thanks for the advice.
