Modem good enuf for Max?

mrapoc · Apr 02, 2006, 11:40:40

Will my Sagem F@st 800 allow me to take advantage of the adsl max services?

Its usb and is branded with an evil TalkTalk logo

Xbandito · Apr 02, 2006, 11:52:05

Well on searching....it is capable of 896kbps......so that is 8mb capable (same as my voyager 205) and as I doubt you will get a full 8mbs, it should be ok.

mrapoc · Apr 02, 2006, 17:24:27

if its nowhere near i will order a cheap ethernet and wireless router. will this increase my 2mbps speed at all?

Xbandito · Apr 02, 2006, 19:23:15

Your modem you have now should do for maxdsl....to get higher speeds depends on your Attenuation and Noise Margin (SNR).
Peeps with more techy knowladge will/can explain it better than me

mrapoc · Apr 02, 2006, 19:53:39

attenuation 22db and bad noise margin 33db

Xbandito · Apr 02, 2006, 21:02:13

well putting them figures in here -:

Gives a nice 8mb

Depends also whether or not you have USB1.1 or 2.0. USB1.1 is only capable of 12Mbit/sec throughput. If you have other USB devices using available bandwidth then this is a less than perfect situation

I really would invest in an ethernet router, you will probably see your linestats improve slightly.

Personally, I installed an ADSL faceplate on master socket and use a CAT5 cable too. All told, from what I can recall from old Speedtouch 330 stats, my SNR has improved by about 8dB (though this varies all the time which is normal) and downward attenuation by 2dB.

Neverthless, it is technically possible for a USB modem even plugged in to a 1.1 hub to perform fine on Max. But it is possible that it won`t. I`d remove all doubt

mrapoc · Apr 03, 2006, 08:31:51

if it doesnt i was thinking about buying a cheap ethernet adsl modem off ebuyer.com
any suggestions?

Jeff · Apr 03, 2006, 13:30:32

Well, I paid only £35 for a Netgear DG632. Not everyones cup of tea as it takes some manual fine tuning to get it to hum sweet, but I`ve got it spot on

Needed to configure some ports in and out for P2P to work as it would slow everything down otherwise (can`t handle NAT pings very well in factory default mode) but I have no bother with it otherwise.

Billion series of routers come very well recommended

Coopes · Apr 03, 2006, 16:48:40

How do I find out what my attenuation and noise margins are please.

What modem/router do you have?

mrapoc · Apr 03, 2006, 18:11:49

Which of these two would you go for?

All i am looking for is the cheapest modem which will allow me to use 8mbps if my current 1 doesnt

Dont know much about that one, netgear user myself, maybe this link may help http://www.kitz.co.uk/adsl/frogstats.htm scroll down the page a bit.

I`ve just downloaded the manual for your router.

You need to log on to your router (http://192.168.1.1) and choose the top button "Wizard" over to the left then choose the tab "Status" which is 4th one along.

Mark, with a DS Margin of 3 I`m afraid you won`t get Max. Maybe get Simon to confirm this but I reckon no

Xbandito · Apr 03, 2006, 22:37:45

Jeff, what snr margin do you need to get Max ?.
For mine has been hovering around the 6 mark and I am still only 2mb.
Sync has now dropped to 7392

Jeff · Apr 03, 2006, 22:52:36

I`m starting to realise a few things

Reading between the lines, I think BT must check on your line every so often, however they do this I don`t know but I reckon that if at the time they "test" it and SNR is below 6, they will auto resync your line until SNR improves. They keep on doing this for 10 days and then wammo, whatever they determine is your best sync rate is what you will always sync at ... I presume

I should have just said 6

Jeff · Apr 03, 2006, 22:55:14

BTW, have you rebooted recently? BTs 75 minutes is getting ridiculous for ya now X!

Xbandito · Apr 03, 2006, 23:03:35

Hmm rebooted.......yup (quite a few times) in the day...let some sit for 30mins etc
just did a check.....sync now at 7360

ooooooo telnet just went mad....warnings ppp down atm vc down
major alarm dsl interface down

Jeff · Apr 03, 2006, 23:11:19

Crikey, you`ve blown it up!

Xbandito · Apr 04, 2006, 10:06:54

possibly...
I now get a snr of 7.5 and everything has moved from "downfast" to "downintrlvd" and I sync at 7552..........but there are now figures in the "rvalue" 16 upintrlvd and 16 downintrlvd

Jeff · Apr 04, 2006, 10:56:08

It looks as though interleaving has been switched on on your line. I thought by default that it would be switched off, though interleaving helps stabilise a line so perhaps BT Trainer felt it needed to do it?

Xbandito · Apr 04, 2006, 11:01:35

So bang goes my future online gaming then

Jeff · Apr 04, 2006, 11:06:13

Well, what are your pings like?

Xbandito · Apr 04, 2006, 11:09:15

I did say "future" Jeff........when they bring out a "popular" game that does not give me motion sickness

Jeff · Apr 04, 2006, 13:16:09

Yes they are. Previously under IPStream or DataStream you would only hope to get 1Mbit with those stats

This evening, expect to see your sync drop as exchange contention kicks in or not, depending on what state your exchange is in VP wise

Coopes · Apr 04, 2006, 13:53:55

Still not getting anywhere near 8mb, but ah I was only on 1mb yesterday, so still big improvement.

Jeff · Apr 04, 2006, 21:29:13

You`ll not get 8MBit, not everyone will. Product is sold as "Up to 8MBit"

Coopes · Apr 04, 2006, 22:17:14

Yeah I know Jeff, not complaining, would be nice to get a bit more
Checked with BT the best I can expect is 3500, like I said up untill yesterday all I could get was 1mb.
so still a happy IDNetter.

Jeff · Apr 04, 2006, 22:59:26

Mark, something strange though with stats you posted yesterday. You posted your SNR (DS Margin) as 3. This doesn`t seem right, could it have been a typo as your SNR is at 6 today with Max? I fed the info you provided yesterday into a checker and it told me you couldn`t expect to see any better than 1Mbit?

Coopes · Apr 05, 2006, 17:43:43

Hi Jeff, both sets of stats where cut and paste so no typo error.
the first set was done when I was on the one mb connection the second
on the max connection.

Mines not to bad this morning but that could change of course

Coopes · Apr 06, 2006, 08:57:20

From what I can make out Mark if I have a DS reading of 0
I don't think I should be connected

Jeff · Apr 06, 2006, 23:54:32

Coopes, I had an SNR of 0 for virtually all of Tuesday evening and line stayed up

Basically, your line will stay up if exchange equipment can still "hear you" and obviously it did
