NTL120 Modem
 

Hi Peeps!

can anybody shed a light as to why my router Netgear MR314 would struggle with the above modem if the ethernet type is set at 100Mbs full ? As I was getting what seemed like 1/2 speed I wondered if the default setting which is autosensing is 10Mbs duplex which I think would equate to approx 5Mbs D/L speed. Net result was that my router would then not talk to the modem at all!!!

modem still works and I have reset it to autosensing and all is hunkydory again!!

I have seen many conflicting posts about the abilities of modems and I am a bit confused about wheter I need to talk nicely to c/s to get a new modem or will it all get sorted in the rollout!!

Re: NTL120 Modem
 

The 120 will only do 5M max due to it's firmware. Experience suggests that setting the ethernet on it to 100 will actually make it worse - 10M duplex seems best, with your PC NIC set to the same (i.e. neither set to auto).

Re: NTL120 Modem
 

do you know if the firmware on the 120 will get flashed or do I just wait for NTL to arrange to install a new modem!!!

the irony is that both of my neighbours have the 1meg service and blue 250 modems !!;)

Re: NTL120 Modem
 

One of those will happen, we have no information on which yet.

Re: NTL120 Modem
 

I've found this abit useful as well. I've set both the Modem to Full duplex 10Mbit and my Ethernet card the same, Results are more stable and much nearer the 5mb Connection, instead of 4mb I was getting.

Re: NTL120 Modem
 

I know I have mentioned this before but I dont think anyone picked up on it, I have a 120 modem and have it set to 100 Full Duplex, as is my Dlink DI604 Router and Intel Pro 100 V Nic.

I am (currently) having no problems on the 3mb tier with this setup, could it be NIC / driver specific do you all think?

Re: NTL120 Modem
 

I only tried the full setting on the modem after i was put on the 10 mb service as i was getting approx 5.2 Mb d/l...3mb was rock solid with only two outages in nearly three years (well done NTL)

Now I know I can get into the modem directly from the pc ethernet connection I am wonering what hether to have another go with 100 half !! but I am quite happy that it is at 5Mb at the mo !! as mates who live in the sticks are stuck at 512 kb !!
;)

I am sure my router should do 100 MB will have to go and check now to see what internet connection it can cope with!!!!

Re: NTL120 Modem
 

I have just been doing some tests d/l headers from the NTL newsgroups, I know the completion rates are s**t but I have always found that I get consistantly top speeds there which make them good for testing.

I found that if I set the Modem and NIC to the same setting I get the following results:

10M Half Duplex. I get a constant 430000 b/s.
100M Half Duplex. I get a constant 470000 b/s.
Auto Negotiate. I get a constant 470000 b/s
10M Full Duplex. Bursty and very slow and stalls
100M Full Duplex. Bursty and very slow and stalls

The ASDSL Guide test Confirms these speeds as follows:

10M Half Duplex. 3917 Kbps
100M Half Duplex. 4361 Kbps

It's early days yet and I wouldn't want to draw any firm conclusions yet but on my system at least "Auto" and "100M Half Duplex" seem to give the best results. I just need the firmware upgrade now, or modem replacement. Before Xmas would be nice :)

Re: NTL120 Modem
 

I noticed on mine 10m half and auto sense work best. I think the modem when shipped used to auto sense to 10 half and seems designed to operate in this mode and I also believes it negotiates with the ubr at 10 half hence the 5mbit max speed.

Now if I use auto sense it puts me on 100mbit but I dont know if it is half or full as windows doesnt show which, my lan card is on auto negot.

Re: NTL120 Modem
 

Same here bud, exactly the same results.

Modem - Both NIC and NTL 120 Ambit Modem set to 10MB Full duplex

1st 128K took 266 ms = 492752 Bytes/sec = approx 4100 kbits/sec
2nd 128K took 265 ms = 494611 Bytes/sec = approx 4115 kbits/sec
3rd 128K took 250 ms = 524288 Bytes/sec = approx 4362 kbits/sec
4th 128K took 266 ms = 492752 Bytes/sec = approx 4100 kbits/sec

Re: NTL120 Modem
 

Just spoke with CS and told these modems will take up to 24mb! Also told that as the 10mb isnt 'officially' yet launched there is still network balancing going on.

Once this has been completed and im still not getting 10mb then call them to sort out

Re: NTL120 Modem
 

I seem to be repeating this a number of times - the Ambit 120 will not do more than 5M without a firmware update. At the moment we believe that ntl are working on this (or Ambit are working on it for them ?). We don't know if they will upgrade the firmware or replace them with a 250 atm.

Re: NTL120 Modem
 

I doubt they will replace the modems, Too much expense, Probably why they said Up to 10mb, Typical NTL Clause/escape goat, if things don't work out.

Re: NTL120 Modem
 

Actually modems are not very expensive, and they would probably post you a new one if they went for a largescale replacement programme.

Re: NTL120 Modem
 

I hope your right!.

Re: NTL120 Modem
 

Unlikely methinks as they will require an engineer install to set them up as they have to get the signal strength correct ASFAIK

Re: NTL120 Modem
 

When i had my modem swapped to an NTL:250 yesterday the engineer just plugged it in and told me it'll take a few hours to get the MAC activated, (probably just a phone call from him to TS). Although that didn't go smoothly as i had to ring them myself! But he didn't checked my signal levels and all is working spot on.

Re: NTL120 Modem
 

Why would the signal strength need checking for a straight swap ? Do 250's need a different strength to a 120 etc ?

Re: NTL120 Modem
 

tis it worth me asking for a new modem then?
;)

Re: NTL120 Modem
 

I think the engineer's have to register the modem paul so sending in the post would need a new procedure in place.

When mine was swapped today he rang a number and did a modem swap giving them the old and new mac codes and took the old modem with him (guess i cant sell on ebay :LOL: )

Re: NTL120 Modem
 

Modems can be pre registerd though, that's how the trial modem I had last year was done. It was just posted to me.

Re: NTL120 Modem
 

Ok this is really starting to bug me now, how on earth are people getting replacement modems, when this issue has been posted to death on here that NTL will NOT send an engineer out to replace the existing model just because there 10mb conneciton isn't 100%. I've rang CS and TS, and they both confirmed and point blank refuse to replace my modem with the NTL250. Even though my 10mb conneciton is so obviously not up to the 5mb At this point.Let alone 10mb

Dammit its just not On :mad:

Re: NTL120 Modem
 

I spoke to TS last night and was told that the firmware has been updated and that there would be a rollout to all UBR's over the next couple of weeks before the official go-live at the beginning of December. Your local UBR will then transmit the firmware to your modem.

Assuming that I wasn't being fed an excuse !!!! The lady that I spoke to was very helpful and sounded genuine.

Re: NTL120 Modem
 

Time will tell as they say...

Re: NTL120 Modem
 

Thats the best news I've heard on here since the rollout! Assuming it turns out to be true like you say!.

Re: NTL120 Modem
 

Sounds perfectly reasonable to me. :)

Re: NTL120 Modem
 

I heard the same of someone else as well, I assume this is going to happen now.

Re: NTL120 Modem
 

Upgraded speed from 3MB to 10 MB by calling C/S.
for three days i was receving 5-6 MB download speeds, now it looks like i am getting speeds of up to 10 MB downloads on some sites, but my modem
(NTL120) seems to be running very hot

Re: NTL120 Modem
 

please can anyone confirm what sort of download speed to expect on 10 MB connection

Re: NTL120 Modem
 

your thumb nail whould be about right
the idea ofsendign out firmware in tie for a roll out sounds perfectly resonsble
/me disapears off to a deep dark corner of the earth to read up on cisco based cable modem systems

Re: NTL120 Modem
 

Is this with a NTL120 modem?

Re: NTL120 Modem
 

yes this is ntl 120 modem

Re: NTL120 Modem
 

seems they started rolling out the new firmware for the 120s now :)

Re: NTL120 Modem
 

yup its true, im in belfast an at about 4am this morning my modem (ntl120) reset, i checked the config page an it says "Software Upgrade File Name : ntlhm120_ntl0002.cpr" and im gettin Your download speed : 7833 kbps or 979.1 KB/sec. Your upload speed : 491 kbps or 61.3 KB/sec. so i guess its true, hehe the 120s do support full 10mb. well im sorted, :D hope rest of yas get it soon :p:

Re: NTL120 Modem
 

That's good then.

Re: NTL120 Modem
 

What ethernet settings are you using Wasted.D? I rebooted this morning, and i'm getting about 5.7mb, still a big difference from the 2.7mb i was getting since the 8th though, so i'm not complaining. :D

NTL 120 Modems have had a firmware update, now 10MB
 

As title, the new config is ;

ntlhm120_ntl0002.cpr

My modem now runs at nearly 1MB/sec. Nice one NTL :)

Re: NTL120 Modem
 

My modem did`nt auto reboot but a quick power down and reboot seems to have done the trick. Now running at 10meg compared to 4.5-5.5 last night.
