Re: superhub 2
 

Thought it had, but could well be wrong - sure someone in the know will be along soon. All I can say is that I've just spent a day in router mode and my TBB was very yellow, but speedtest, pingtest and my samknows box gave similar results to modem mode.

Re: superhub 2
 

Seems pretty good to me though in SH2 router mode, but i am no expert, but i think Seph knows alot more about this. :)

Re: superhub 2
 

Enginner did not check any Wireless channels? Could that possible solve the issues?

Re: superhub 2
 

It'll let you see which channels are less congested. I check regularly as I don't set the channel to automatic.

Re: superhub 2
 

He may not want to say that, but I will! ;) However if/when Seph re-engages he'll no doubt quite correctly point out that he conversely does not currently experience that level of jitter in RouterMode.
I believe that may be explained and dependent on combination of T patch level and concurrent utilisation/load on DOCSIS chipset and thus the overhead of subsequent line conditioning on individual connections.

De-prioritising ICMP/traffic targeted specifically at a router rather than "beyond it" is after all not uncommon. ;)

Like no doubt yourself and many others I don't rely on a single diagnostic either - I run other BQM/ping plotters in parallel in addition to SK monitors (I use the plural deliberately as perversely for a short period over last week or so I am literally running two seperate SK units in parallel! :cool: )

That's in addition to also monitoring typically a minimum of 2 or 3 other CMTS subscribers TBB/BQM monitors remotely in my Brighton cluster.

Just for your further amusement, early in May I was stress testing my first SH2(yes I'm now on my second) by saturating my upstream (that I knew had an open utilisation fault on both d/s & u/s) with following colourful result:

Re: superhub 2
 

Do you think you have changed some settings in the SH2 that may account from your extremely rare normal looking graph?

I would be grateful if you're able to list what is enabled and disabled so i could possibly try and replicate your result. :)

Re: superhub 2
 

FIREWALL
Firewall Disabled
Firewall Protection Low

If I turn fireqwall on, it makes no difference.

Good luck.

Re: superhub 2
 

Thanks for your help, i will change that and see what happens but i don't expect any change.

Re: superhub 2
 

Well it didn't make any difference.

Re: superhub 2
 

Didn't expect it would. As I've said before, VM have offered me no explanation on the trial forum as to whay I have this TBB report in router mode. If there was a neighbour with a SH2 .....

Re: superhub 2
 

I wish they would respond as something is clearly happening, although as it appears it isn't affecting my connection i guess it isn't a priority.

My computer was switched off from around 21:45 till 1pm and it still spikes on the graph.

As soon as i turned the computer on going by the graph the maximum latency shoots right up and even reports some packet loss, however from doing a ping test i am clearly not getting any issues that i can tell.

http://www.thinkbroadband.com/ping/s...08-06-2013.png

http://www.pingtest.net/result/82328349.png

Re: superhub 2
 

I've seen this behaviour before, it happens on some Draytek routers as well due to the ICMP requests being put on a lower priority. That's why the connection is unaffected.

Here's an example of what I mean (from my work connection, which is not VM):

http://www.thinkbroadband.com/ping/s...03-06-2013.png

Looks bad, but the connection is actually fine.

Re: superhub 2
 

I guess changing the ICMP requests priority would need a firmware update and having them higher or lower would that cause an issue somewhere?

Re: superhub 2
 

If there's nothing else doing traffic when the PC is swictched on (after it's settled down), ICMP pings wouldn't need to be demoted. From Kush's TBB, it's clear that there is activity (avergae latency varying).

Same with SnoopZ's. Perhaps SnoopZ can advise.

Re: superhub 2
 

All i have to do on the PC is switch it on for it to start spiking yellow, if i fireup a browser then i get far more yellow spikes.

Not sure if it makes a difference but i am using Windows 8 and Google Chrome, i also have a galaxy S3 connected to wifi all the time.

I have just remembered i get the same kind of graph with wireless turned off so that discounts my phone.

Re: superhub 2
 

I'm fairly sure that most Idle PC's probably still have some kind of activity - programs checking for updates, email programs, steam, anything that runs in the background and requires a connection really. Hard to say as every machine is different but there's definitely something going on here I think.

Then again, we have about 6 servers that are online 24/7 and they don't seem to affect the graph as much.

Re: superhub 2
 

I have just plugged in an old Netgear WNR2000 only capable of 100meg but its all i have in terms of a router to test with SH2. And so far im seeing ALOT lower latency when compared to SH2 in router mode.

Im limited to 94mb on that router due to the 100mbps port

So in a nut shell im actually quite annoyed that i now need to buy a router ontop of the £49 i just paid for the SH2

Will also setup a Thinkbroadband ping monitor over night and compare the two .

Got an Asus RT-N16 Coming on Tuesday with DD-WRT should run a treat, Not bad for £60.

Re: superhub 2
 

yup, and let this be a lesson to everyone. If you need a modem get a shub 1 and put it in modem mode and then by yourself a proper router, especially if VM are going to charge you £50 for one.

Re: superhub 2
 

Use tomatoUSB it runs alot better than ddwrt

Re: superhub 2
 

I would also consider the Asus Merlin firmware which now supports the N16: http://www.lostrealm.ca/tower/node/79

Re: superhub 2
 

I'll second that.

Re: superhub 2
 

Hi all,

I'm new to the fourm, I just wanted to ask seeing as I had got the new superhub 2 for a fee. do they all have blue LED lights and lack of virgin sign on the front of then or are they supposed to be the same colour of LED and virgin sign on the front as shown on this webpage from virgin http://help.virginmedia.com/system/s...MER_TYPE=Cable many thanks lee

Re: superhub 2
 

The first batch seem to have all blue leds(my prefered choice) all the trialists got them first, not sure if anyone has one of the green leds and crappy logo on the front yet.

Re: superhub 2
 

Is there a decent guide to putting tomatoUSB onto the n16?.

Re: superhub 2
 

download the firmware from tomatousb, then upload it into the routers GUI

Re: superhub 2
 

yeah I thought that, I got one with the blue LED lights as an upgrade from the shub 1.

Re: superhub 2
 

Can you give me an exact download link?, im looking here: http://tomatousb.org/download but cant find which one i need for the n16 sorry to be a pain :erm:

Re: superhub 2
 

The green LEDs in the VM photo are misleading. Green means that the circuit is operating under the DOCSIS 1 protocol (not used except for the intial booting). The LEDs will be blue when DOCSIS 3 is acquired for thr 30 meg and higher tiers.

AFAIK, the VM tirallists received production models which don't have the VM logo above the WPS button.

Also, to make life even more different, the front panel LEDs are described by VM as being on the side panel. Which side panel is that? The front one or the rear one? LOL.

Re: superhub 2
 

Any of the K26 builds, im running MIPSR2-beta K26 USB Ext

Re: superhub 2
 

I thought that to some degree too, mine dosnt have the virgin media logo above the wps and mine was an upgrade from the shub 1, is that normal?

Re: superhub 2
 

It should work just fine without the logo. ;)

Presumably the logo will be on subsequent production batches.

Re: superhub 2
 

nah I was just wondering thats all lol

Re: superhub 2
 

got my one SH2 nice and early set up alot better than superhub 1 my wireless was going up and down on old one solid 4 bar on new one

Re: superhub 2
 

Has anyone got a lower RxMER (dB) on the Superhub2?, These are my current power levels on SH2 Around 38: http://postimg.org/image/95auh9v8r/

On my old superhub the RxMER was allways well above 40.

Not sure if its a problem with the UBR i connect to or if its to do with the SH2. Doesn't effect my connection just found it rather odd.

Re: superhub 2
 

Mine are around 38, which is well within spec i think. They were a little higher if i remember correctly on my SH1.

Re: superhub 2
 

Mine are around 38 too on the SH2 http://postimg.org/image/69kw7sfu9/

Re: superhub 2
 

how does one get the new super hub :O

Re: superhub 2
 

via retentions dial 150 from a Virgin Media landline, then select menu option 5 then option 3 and they can post you it and all you pay is the postage costs.

Re: superhub 2
 

why are you guy assuming the worser graphs are due to the SH2?

Looks to me seph simply has lower network utilisation in his area.

---------- Post added at 16:54 ---------- Previous post was at 16:48 ----------

the guide I used is. ( i think ) I used shibby.

http://moonlightknighthk.wordpress.c...n-asus-router/

Be aware one of the shibby builds boots so slow it feels like its bricked but isnt.

Tomatousb is indeed very nice, but with a bad weakness that pretty much any config change triggers a full network restart, shouldnt be an issue on VM but was bad for me on BT with its dynamic ip system.

tomato-K26USB-1.28.RT-MIPSR2-102-AIO.trx is verified stable by me.

build 104 has the weird slow boot freeze issue.

Re: superhub 2
 

I don't thik so, Chrys. Nowadays I get around 80/6 at peak times. And the upstream rarely goes above 8 meg during the day.

Re: superhub 2
 

If that's all I got for my 100Mbps connection I'd drop a tier

Re: superhub 2
 

Well, it is up to 120 meg. if I dropped a tier, it would only be up to 60.

Re: superhub 2
 

True... but I'd guess you would get close to 60 most of the time, unlike the 120 where you say you tend to get 80 at best.

Re: superhub 2
 

That's the difference in philosophy between the two of us. I'd rather have 80 than 60.

Re: superhub 2
 

and then there's another difference in philosophy where I would expect my ISP to do at least the bare minimum and not drag their heels. You have ISPs like Sky and BT who install the necessary capacity, as well as ample spare capacity to provide a better user experience, then virgin who dont add enough capacity to allow users to reach full speed

Re: superhub 2
 

to be fair 70% of max speed at peak is brilliant for a VM connection. :)

I guessing seph gets full speeds off peak.

Re: superhub 2
 

does anyone get lag with u new superhub had bad lag spike while gaming

Re: superhub 2
 

Quite often ill shoot upto 100+ for 10 or so seconds then back down again ( Counter-strike 1.6). Its one of my reasons for getting a router, That and a lower ping.

Re: superhub 2
 

Because i have what i call a perfect SH1 graph and the second i started using the SH2 it looks terrible like most other SH2 graphs, so it is definitely the SH2 causing it. It even looks like that without any network activity, but gets alot worse the second i turn on the computer and start browsing. However it doesn't seem to affect my connection.

Re: superhub 2
 

Have you turned off IP flood protection? I play BF3 on the 360 and usually i don't get any lag and any lag i do get i put it down to the server now.

Re: superhub 2
 

Who cares what the graph looks like aslong as the connection isn't affected?

I had a really bad graph since the trial started:

I decided to do a button reset last week:
http://www.thinkbroadband.com/ping/s...04-06-2013.png

Graph improved but my connection was perfectly fine at both times.

Re: superhub 2
 

i turned it off and was getting bad lag on fifa it was just me as my mates was fine

Re: superhub 2
 

Your images are not showing.

Re: superhub 2
 

I have had really bad Lag on fifa this evening. I have SH1 in Modem Mode so i think its down to EA Servers or an Issue with Virgin but SH can't be blamed.

Re: superhub 2
 

thanks for that i'm not the only one then

Re: superhub 2
 

ok assuming same US channels etc.

its possible the superhub2 is playing priority games with ping packets.

Re: superhub 2
 

i get the same SH2 graph with any US channel, but atleast it doesn't seem to affect my connection as jitter is only 0-1%, far better than what i had with the SH1. :)

Re: superhub 2
 

It's well known that the SH2 produces poor TBB graphs (in router mode, at least). However it's generally noted to not affect the connection so the current going theory is something to do with the ICMP packets being on a low priority.

Re: superhub 2
 

This theory was raised in the Trial - I disproved it to my own satisfaction.

I used the Windows "W32tm" command to measure round-trip times to Virgin Media's NTP server (this was using UDP packets directed at port 123, rather than ICMP). I got very similar results to TBB).



The command I used was:

w32tm /stripchart /computer:ntp.virginmedia.com /dataonly /packetinfo /period:1 (/samples:20)

If you want to reproduce the experiment.

The fact that people can't feel the effect is another matter!

Re: superhub 2

Re: superhub 2
 

I agree that it's up in the air as to the main cause, that's just what's been put forward as a reasonable explanation. So far, I've yet to see anyone suggest another reason.

I would say that if there was an effect on the connection, people would surely have pointed it out by now given how terrible those graphs are.

Aren't you the one exception to this rule due to having a different FW version or something?

Re: superhub 2
 

Nope - same firmware as other triallists who reported a particular peculiarity.

Re: superhub 2
 

It's reasonable to put it forward as a theory ... but it doesn't become fact, just because no one is in a position to disprove it.

But anyway, thinking about it: "priority" would only explain the symptoms when under heavy load - most of the TBB graphs I've seen show the same effects in the dead of night when the connection is not otherwise 'in use'. It would be a strange algorithm that purposefully delayed ICMP echoes, when there was no other work to do.

Here is an overview of the data from my tests. This is a real application, suffering a real degradation in its performance.

My line speed is 30Mbps/2, but with the old Draytek in circuit, the downstream is more like 10Mbps - yet latency improved dramatically.

If these UDP packets had been from a game, or a VOIP application, they would presumably have been affected in exactly the same way.

Re: superhub 2
 

hi everyone i just got the superhub 2 yesterday, and had a load of nightmares with it already, my connection, goes of, for about 5 mins then comes back on, it has happened at random times, i rang them up about this and they said it is a known fault with the superhub 2 at the moment and they are trying to resolve this with a new update soon, anyone else had this problem ?

Re: superhub 2
 

We'd need to know what "connection goes off" means. Is it that the SH2 reboots (the lights go off and then only the arrow flashes, rtc), or is it wireless that drops but the SH2 doesn't reboot?

You could post the network log and tell us where in time it happened (the log shows 1 hour behind BST).

Re: superhub 2
 

not got a clue how to do a network log, and it happened about 4.40pm, today, it is hard wired my pc connection, so nothing to do with wireless, and i diddnt really look at the superhub 2 when it happend, but my guess is it rebooted itself, for some reason, is there no way of putting the netgear firmware back on and taking virgin firmware off, then it would prob be working perfect

Re: superhub 2

Re: superhub 2
 

Really? I must have misread a post (or got you confused with someone else). I apologise.

Yes, you are quite right about that. I certainly didn't mean to imply it as fact, it was more I was trying to get across that the SH2 graphs are known about and have been reported and that was just the going theory that I've seen (mostly due to the lack of an alternative theory). I have seen someone post a graph that shows ok at night then hectic in the evening though (hence why my suspicions went straight to the ICMP thing, as my work connection's router definitely does do that and the graphs were remarkably similar) but it seems many people are getting different results with the SH2. One thing the majority do have in common though is that despite the graphs, their connection does seem pretty stable.

Re: superhub 2
 

i no the maybe a long shot but has anyone else got a vodafone sure signal working with new superhub as mine stop working as soon as i connected it

Re: superhub 2
 

Not a Vodafone Sure Signal user myself, but I understand it's firewall related. Try Firewall set to "Low" and all the pass-through options enabled.

I believe that works, in which case, you could try some other combinations and see which ones are actually pertinent.

Re: superhub 2
 

Have you looked here: http://www.cableforum.co.uk/board/87...re-signal.html

Re: superhub 2
 

You just need to enable IPSec pass-through (firewall has to be on to change the setting, but should remain changed thereafter)

Re: superhub 2
 

he has brought the downstream lower, and that looks good, however the upstream is looking a little low to me

Re: superhub 2
 

yeah defo, that is the lowest I have even seen. I thought the modem was supposed to incrementally increase the upstream until it gets to the right level of power?

yeah, I doubt they are stupid enough to start bragging about stuff that is as bad as the shub1

Re: superhub 2
 

Ive seen 29 for an upstream a few times,

Re: superhub 2
 

I ran on 29 dBmv upstream for nearly two years. It's either a duff modem (unlikely) or, because you're near the cabinet, all that's needed to push your signal to the first active node.

Re: superhub 2
 

When i am doing speedtest i am getting 100 down and 4.98 up.
