new samsung boxes more trouble then they worth?
 
Hiya all now i connect through a cable stand alone modem myself as stb connection was a big no no.

We was okay with our old digi box and c+w keyboard but due to some error it had they replaced it with this Samsung thing and purple ntl keyboard.

There is no rear audio sockets ( thats hif fi sound gone ) the keyboard is worst I have seen and to use.

Its sluggish changing channel

We want our old box back :rolleyes:

Seems we have taken a step backwards and my dad is seriously thinking of jacking ntl in if they wont change this stupid box and keyboard for something which works.

You'll need one of these...

...scart leads, code VA23A from www.maplin.co.uk

I've had no problems whatsoever. I find that it's the opposite, everything is quicker. I don't use a keyboard, so I couldn't comment on that.

Plus it now matches everything else, colour wise ;)

Re: new samsung boxes more trouble then they worth?
 
If your video has audio outs, set your video to the av channel and use them - thats what I did. (I hardly ever record other channels on the video, so it just stays on the av channel).

I also have a samsung, and on the odd occasion, it can take a second or two to change channel, sometimes longer, but mainly you can quickly scroll through the channels with practically no delay.

Sometimes though, if I have Azureus running (Bit torrent), web page browsing can be slow (sometimes over 30 seconds for a page to fully load), even though its downloading at only say 20-30K, and uploading at about 10-15K (1 meg connection)

Does whamming data through the box affect the TV at all?

Also, hows your PC CPU and RAM doing when you're doing a lot of P2P? What's the actual bandwidth usage?

(Had to vote 'no' btw, I know the technical details of why they're better :) ).

Kneebs 18-08-2004 11:13

Re: new samsung boxes more trouble then they worth?
 
CPU hovers between 10-30% (XP 2800+), memory sits at half a gig free (1 gig total mem).

Bandwidth is often less than half of whats available (can be downloading at only 30-40, uploading at 10-15), and web browsing can be alot slower than normal.

If I'm downloading flat out (rare), the box can sometimes take a couple of seconds or more to change channels, although I'd say this is quite rare, and sometimes happens even if not downloading, so I don't think its that what causes it.

Ramrod 18-08-2004 11:21

Re: new samsung boxes more trouble then they worth?
 
I think the new box is better. Channels change much more quickly now. The old pace box acted like it was on a go slow.

Kneebs 18-08-2004 11:23

Re: new samsung boxes more trouble then they worth?
 
Another thing I have noticed with this box, which never happened with the Paces' I had, is that occasionly, the sound will 'pop' and the volume level will drop so I have to turn the tv volume up. At least I don't have to reach for the tv remote to do it tho ;)

Feenix 18-08-2004 12:02

Re: new samsung boxes more trouble then they worth?
 
The Samsung boxes are a breath of fresh air around here. The Pace boxes are slow, ugly and outdated - Samsung's STB is much faster at changing channels, interactive, anything to do with a menu system and can handle 1.5mbit broadband not forgetting it is shiny silver too.

As an install tech you can pretty much rely on a Samsung to work first time. On the other hand Pace boxes tend to not work, most of the time... imho

So two thumbs fresh :tu: :tu: for Samsung and a :td: for Pace

Lucky you - I find that caning it on P2P markedly slows down anything on my XP3200+, but it only has 512Mb RAM... :cry:

The BIOS could do with some tweaking too, mind.

Re: new samsung boxes more trouble then they worth?
 
I'm not convinced that it is better or worse.

The digi TV seems OK and responsive, mostly, but I have had some picture freezes. The lack of phono ports was swiftly dealt with by the installing engineer who provided a scart with phono cable. The STB remote is supposed to be able to control volume, or so the engineer said, but it just gives me the old PACE type message, to use my TVs remote.

The broadband seems appalling. If I'm on the silver service, why does it take 10 seconds to load the average web page :confused: Dunno if that is due to P2P (which is throttled right down, and averages only 10mbps up/down,but it dont get much faster when I switch P2P off), if I put the router onto the smasung, it'll crash within a day. But is this the Samsung, or is it a signal fault. I'm just never in at the moment, at the right times of day, to call faults to give them an ear bashing :angel: .

Still it's a nice colour and I don't think it's quite so good a room heater.

Right, I've been doing some testing with uploads / downloads / p2p with the samsung...

When doin no downloads / uploads or no p2p running, pings to www.bbc.co.uk take about 20ms, with no packetloss whatsoever, web pages take about 4-5 seconds to fully load

uploading alone to ntl webspace (at 25-30Kb /s), ping time increases to around 150-200ms, some packet loss (3%), web pages take about 10-15 seconds to fully load.

downloading alone from download.com (at about 110Kb/s), ping times jump to about 150ms, no packet loss. web pages take about 8-10 seconds to load.

Uploading to ntlwebspace and downloading from dowload.com together....this is where it gets bad !! downloading drops to 25-30Kb/s, uploading drops to about 16Kb/s, pings average about 150ms, webpages take about 20-40 seconds to load fully.

when p2p (azureus - bit torrent) is running, with download rate 40-80Kb/s, uploading at less than 15Kb/s, average ping is about 60ms, packet loss is 32%, and webpages take over 40 seconds to load , and occasionly the page doesn't load correctly (see attached)

Anyone else suffer from this, either on a samsung, pace, or SACM ? My PC aint the problem - CPU sits only runs at 1-30% through all this, and ample free memory. Is this the norm, or is it a problem, and am I likely to get fobbed off by tech support ?

Cheers :)

Re: new samsung boxes more trouble then they worth?
 
Any chance of running the tests on another PC, i.e. one connected through the same STB via a router or something? i.e. have P2P running on the main box and monitor the pings on the other?

Actually, I'd be interested in anyone's tests along these lines, particularly the packet loss element, I'd expect the p/l to be near 0, but the ping times to shoot up with increasing P2P load. Will try at home on DSL.

Re: new samsung boxes more trouble then they worth?
 
well i was downloading some concert videos last night from BT, i had 3 Simultanious connections going and all were running at around 30kbs each..

if there was any packetloss i'd know about it, because the videos would never have Succesfully Downloaded (Bittorent automatically redownloads Failed packets and i never had a single one after 11 hours).

its also Not illegal to Use P2P apps (regarded the content you DL isnt Copywrited) so theres no Way they Should be Banning the use of P2P unless they can prove exactly what your downloading (then that becomes a Privacy violation).

Well, as you can see from the two attached screen shots, main.jpg is my main pc, with azureus client running - you can see in the bottom right corner the upload/download speeds, and you can see the ping results. :erm:

networked.jpg is my other pc (connected thru the main one via ICS), with just the ping running.

:erm: the networked pcs' packet loss is 38%, and the main one is 36% - not quite the near 0% we suspect it should be !

Any ideas ?

Like you say, bit torrent automatically re-downloads 'missing' packets, so you wouldn't know by using bit torrent alone that you were suffering packet loss. Can you try running a ping test (eg ping -t www.bbc.co.uk - press control-c to stop) once bit torrent has been running a while, and post your results here ?

I take it you're on the 1meg / samsung STB aslo ?

Cheers,

Right a (fairly) quick call to CS to swap the broadband config file to the pace box downstairs (I used to use the box downstairs for internet, so I already have the cabling installed to upstairs) and heres the results....

Only a few packets dropped on each PC, resulting in 0% or 1% packet loss on the PCs. Note the almost constant download rate through azureus of over 100KB/s - I don't think I've had anywhere near that speed through azureus using the samsung box (using the same torrent yesterday on the samsung earlier today i was lucky to get 50KB/s) :( .

I know its not the cabling to the STB upstairs, as this problem has only appeared since the samsung was installed. Should I ask for another samsung, or can I get a SACM ?

Oh, and I spoke to Tech support last night (after 8pm so I couldnt get CS to swap the broadband round), who warned me that if the pace box gets the 1.5meg upgrade, "the box will literally blow up, I'm not kidding" I could hardly contain my laugh :rolleyes:

Just in case anyone is interested, the middleware that is running on these boxes is Tsunami by Livewire. More details here: http://www.livewire-tv.com/tsunami.html

although I have not been able to discern whether there is any sort of filtering available with it yet.

Well, after speaking to a helpful guy in Tech Support, who referred my problem to the faults team, they rang me back earlier to sort out an engineer visit for tomorrow morning - hopefully I'm gonna be given a new samsung box, or a SACM...I'll let yous know....

Well, 1 new samsung box later, and the same problems are still being experienced.... I've now arranged for a SACM to be installed - I just gotta wait till 1st September for it to be done...

Nutty 21-08-2004 15:52

Re: new samsung boxes more trouble then they worth?
 
I'm sorry, but measuring broadband performance on boxes using p2p is probably the most wrongest way you can go about it.

Saying you get 100k on box x, and 50k on box y, is bollox, as it all depends on how much other peers are uploading, how hard the seeds are getting hammered, what position you're in in peers queues, time of day, etc etc...

If you're uploading at 15k, and downloading at 100k, then you do realise that every packet that is recieved using TCP, it has to send an acknowledgement packet, to say it recieved it ok? Typically on 100k down, you're looking at about 10k up in acks alone, add on your 15k upload, and all the bandwidth for keeping 100's of connections to peers open, and you've pretty much max'd out your upload. Thats why it takes ages to download web pages.

Kneebs 21-08-2004 16:10

Re: new samsung boxes more trouble then they worth?
 
Nutty,

Please (re?) read post numebr 15 - I've also tested using uploads to webspace / downloads from download.com, not just P2P - when uploading to webspace, download speed from download.com drops to 25-30KB/s (through the samsung). Some loss of speed would be expected due to ACKs - on the pace box, the download speed only drops to 80KB/s.

38% packet loss is the main cause of my slow web browsing, not saturated up/down stream. On the Pace box I'm currently conencted through, even downloading flat out via P2P, browsing, although slightly slower than normal, is a damn sight faster than through the samsung box. I suffer next to no packet loss through this box :)

Nutty 21-08-2004 20:58

Re: new samsung boxes more trouble then they worth?
 
Sorry I didn't read the 2nd page.. ;)

Whats the cause of the packet loss? Most likely a bad connection rather than the samsung box itself.. or it could be a bad box. Not in general, just yours.

It would be very bad, if all these samsung boxes ntl are dishing out, had some severe flaw. I'm sure they must be capable of having 0 packet loss on the cable modem built in. They'd all be recalled with packet loss like that.

Well, I'm edging my bets towards a problem with samsungs in general - not everyone, 'cos there's people here who say they have no problem. The two samsungs I've now had have both had problems with bad packet loss - I doubt its the connection, 'cos a) I didn't have any these problems with the pace that was connected to the same wire, and b) the engineer hooked up some sort of tester to the cable and all was fine this morning.

Re: new samsung boxes more trouble then they worth?
 
Just been running Azureus, and with it running, but with bandwidth spare, I cant get on virtually any websites.

I know its not bandwidth related, because I couldn't even reach my router setup page, and thats on a 100Mbit network.

I'm using a pace 2000 STB for my broadband, but its nothing to do with that, as I should be able to reach the router page regardless of the WAN connection type.

It seems Azureus seriously hogs networking resources. As soon as I shut it down, everything went back to normal.

This is on my missus PC, which is only a 1ghz athlon 512MB ram, win2k SP4.

On the Samsung STB`s your BB usage shouldnt effect the TV as (i beleive) the Samsung has a seperate CPU for the BB conection and another for the TV conection (unlike the Pace STB)(please correct me if im wrong)(as have had a rather large amount of vodka)(inafct rather cheap vodka)(....must stop using commas for no reason........................):p: :beer: hic...oooo

Thats correct - samsungs have seperatue processors for broadband / broadcast.

You must be drunk - there isn't a single comma in your post ;)

Nutty 24-08-2004 19:31

Re: new samsung boxes more trouble then they worth?
 
I think I know what the problem is, regarding slow pages with azureus running. Its todo with the amount of network connections used. There are limits in windows, routers, and most likely the cable modems, as to how many connections you can sustain at a time.

Having azureus use most of these connections for itself, results in webpages having to load everything through a single connection, which is not how a web page normally loads. It normally downloads all the images, and seperate frames simultaneously using many connections.

I had an old Belkin router that would crash everytime I used CounterStrike server browser, because it opened too many connections.

Does anyone know the maximum number of connections supported by STB and SA cable modems, or on the ntl network ?

I don't know if its the cause of everyones problems, but I do know my problem is down to packet loss when using the samsung STB, not the number of simultaneous P2P network connections made. Packet loss occurs whenever I'm doing any up/down loading, be it P2P, FTP, downloading from a website etc. I'm told this is a known problem with the samsung STBs, which is being investigated......

Nutty, if you're on samsung STB BB, try doing a continuous ping to www.bbc.co.uk (ping -t www.bbc.co.uk), then set a large (3-4 MB) FTP upload (for example to your webspace)away with no P2P running . Watch those packets drop ;)

I'm on a PACE 2000 unfortunately.
Was thinking of upgrading to 1.5meg for a bit, to get a nice samsung box, but I dunno now.. You've put me off.. ;)

Nutty 25-08-2004 21:08

Re: new samsung boxes more trouble then they worth?
 
BTW, I'm sure someone on these boards said, that ping requests were low priority, so chances are UBR's or routers will drop them, if they're being hammered by heavy use.

Maybe pinging isn't the best way to look for packet loss?

Scorpio 31-08-2004 20:06

Re: new samsung boxes more trouble then they worth?
 
I have had the new Sammy box installed, and i beleive the problem were all having is duplex Missmatch, basically ive heard from someone i know at NTL that the Samsung boxes work better on Half duplex, instead of full, which maybe why were getting all these problems, thing is that my Router cannot be changed and most wont be able to be, if you have a network card try adjusting the duplex to 100 Half.

This is quite astonishing really considering its a new design, 100Mbps full duplex should be the norm, and i cannot understand why it should work better on 100 Half, unless the ethernet port on the box has been set for half.

Anyway we all need to look into this further....

what does Half duplex Do, what are its performance drop offs over Full duplex??

I have been with NTL 3 years with the blackl stb will they change that in the future and the cable box as well?

Basically Half Duplex means the transmission of data can only happen one way at a time, eg send or receive, and full duplex is sending and receiving at the same time, this is probably why your P2P sharers are fooking up, as they upload and download at the same time.

PS ive asked for a seperate cable modem and NTL said i could have one free. There coming round next week to fit it.

but doesnt this render it impossible to play online games?? Xbox uses both the upstream and downstream constantly anlong with the pc games..

i play ww2online with Teamspeack and theres constantly Large ammounts of Downstream and upstream, if its really a Duplex problem it doesnt make sense at all.. My connection never dropped atall for a week then suddenly i get it 4 times in 2 days while not even using it, maybe the Upgrades are causing these annoymolies, Maybe your being unhooked from NTL's routers for a split second causing total loss of Downstream...

i played last night without any problems so it seems very random.

10Mb/half duplex is easily enough to handle full speed two-way transmissions at cable modem speeds. The half duplex bit happens a couple of layers below the actual protocols like TCP and UDP. In fact, TCP overheads are way more of a problem than any duplex settings.

The Samsung STB has a 100Mb ethernet port. The Paces all have 10Mb. It's possible that this would show up cabling issues if you suddenly started running at 100Mb on cabling that worked fine on 10. In any case, since 10/half is ample, you might as well set this and reduce the demands on your cabling.

(and yes, I know the box should work fine even at 100Mb on proper cable, that's what we're looking at).

Mat @ Half duplex, the reason your gaming may work is because of the size of the packets being transmitted, when running half duplex, cabling is not an issue anything cat 5 or above i.e cat 5e or high band cat 6 will be able to transmit 100mbit through it, and most of us will be using patch leads or long network cables most definately cat5 or above, so the 10 mbit and 100mbit isnt an issue, its the half and full duplex issue, if your getting duplex missmatch, ie 1 end send and receiving and the other can only recieve or send at any one time, thats when collisions happen and the packets are dropped. Hence the poor P2P results as you upstream and downstream are getting battered as well as many different TCP / UDP ports being operating at the time.

The routers at the core site when NTL place them wont be the problem, as all there doing is routing the subnets, the DHCP servers at each core site lease you the IP and other relavent DNS and domain details. The problem wasnt around when we had the Pace Boxes, and ive had confirmation from NTL that it is a Duplux Issue.

Just thought I'd mention a tip for those with browsing probs whilst using Azureus. In Azureus, keep the configuration tab open, & when you want to do some browsing, change the UL speed limit from 0 to 5, then when you've finished browsing for the moment, just right click the box & Undo. When you want to browse again, just Undo again.

I'm on the 750k connection with a SB3100 SACM, BTW, incase anyone's interested.

Re: new samsung boxes more trouble then they worth?
 
My Samsung seems happy negotiating a 10Mbps half duplex on a Kingston KNE111TX nic ;

eth1: 10 Mbit, half duplex, link ok
product info: vendor 00:00:00, model 0 rev 0
basic mode: 10 Mbit, half duplex
basic status: link ok
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
advertising: 100baseT4 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

I have tried to force 100/fd using mii-tool with no luck. It also seems to take ages to negotiate, so much so that my Smoothwall gives up, and I have to wait until the nic lights come on and then refresh my red nic interface to get an IP.

Same card used to negotiate 10/hd immediately with the Pace DiTV 1000.

Any ideas ?

I've just started with NTL and the STB they gave me was a PACE model. I find the thing hellishly slow and unresponsive when changing channels, using interactive etc. By the sounds of what ive been reading on the forum it the Samsung box seems to be an improvement in terms of speed. Can I demand a Samsung box from NTL? or do I just have to stick with what they give me.

My Pace suffered from bad slow down to the point of lock up, buttons not responding if I was doing alot of P2P on the 1Mb connection.

I'm guessing that 1Mb on a DiTV 1000 was pushing its capabilities. If you ask for another, I'm not sure if you can specifically ask for a Samsung ?

The Samsung has no problems now when I'm downloading on P2P

Re: new samsung boxes more trouble then they worth?
 
My BB is connected via a cable modem so doesnt affect the box at all. Its just the responsiveness of the box that im frustrated with. It takes an age to change channels, bring up menus and my interactive services are a joke(5 mins to bring up the menus at times - then when I select something the screen goes white and doesnt recover). I always thought my Sky system was slow but compared to this its lightning quick. Could there be something else causing this other than the box?

so if i switch down to "Autonegociate 10Full duplex" instead of 100FD will that help??

Maybe, but 10 half duplex is reported to be better.

Just had my PACE STB changed to a Samsung one. Why does the Tech insist in changing the TV from RGB to Composite? RGB is a better picture

I've been experiencing all the same problems as Kneebs has described. I thought the Samsung replacement (which arrived last week) would be the end of my problems (namely the frequent crashing of the Pace 4000).

Alas, whilst the Samsung hasn't crashed (yet) it performs worse than the Pace did. So i have now done what I should have done a long time ago when I cancelled the digital TV - get the STB swapped for a SACM, which is hopefully coming on Friday.

Are you langley or ex-cwc?, only ex-cwc areas can get samsung box's.

Has anyone noticed a volume reduction on the samsung boxes too? Our Pace 2000 used to be very loud and clear - but the samsung seems so much quieter...

Hi,

I fancy getting myself a nice shiny new samsung box.
If I was to phone ntl and upgrade my Broadband to 1.5MB for 1 month (although not telling them at the time), would they replace my current PACE2000 box?

Once I revert back to 300K BB, do I get to keep the Samsung?

(The only reason I'd like a samsung is so it matches with the rest of my decor)

I just tried that. Had 0% packet loss, ping times went from 15ms to 450ms average

Half Duplex Makes my connection struggle to a point where i get 0 upload when im downloading a file, im getting increasingly ******ed off with NTL and am about to Stop my subscription unless they sort this crap out..

funnier yet, CS are refusing to do anything abou tit.. ******s.
