I asked for a Whoosh test since eversince I upgraded to 2mb from 512k I suffer random frequent disconnections and its driving me nutz !

Is this good or bad for a 2mb line?

43 Db attenuation (loss) downstream is the theoretical maximum for 2Mb, and yours is a bit worse than that.

But quite a few have figures of 47/48 and run 2Mb OK.

Your SNR is important too, but the whoosh test doesn't give this. Many routers do, but if you don't have one of these, I don't know how to get it. That may be your problem.

Have you tried better quality filters - this might help.

Yeah I noticed ADSL modems dont have SNR figures anywareSad

Better filters? not that I know of ive just got the 1 microfilter downstairs...When I got time ill bring the whole PC downstairs and connect directly to the BT socket since am running a 30metre old BT extenstion cable...got a feeling could be that, was ok for 512k though...

I was also just thinking of splashing out on a Netgear Wireless ADSL router and ditch Wires altogether, you reckon that may do the trick,? Am thinking it may provide a stable/easier connection.

Trying your connection at the master socket will be a good start. The old extension cable may be a bit iffy.

As I'm sure you are aware 2mb connections are more sensitive than 512.

A router, and certainly a Netgear one, should show an improvement over a modem.

Splash out on good quality filters also, you will appreciate the difference.

Thx will try both test hopefully this week...

I think people are right 2mb is very sensitive, alot more then 512k anyhow.

Some modems show SNR and ATTEN figures! What is your modem?

Re: SNR from a Frog

:roll: Hmmm I read somewhere that it didnt work for the usb frog! :? Thats why I said he may be out of luck.
I hope I am wrong though! Smiley

My Whoosh test results

Got this from my Netgear DG834G today:

Downstream Upstream
1152 kbps 288 kbps

Line Attenuation
50 db 12.5 db

Noise Margin
23 db 26 db

I,m connected to an extension as the BT engineer showed real brains when they put the lines in ( its a new house) and put the master socket in my front vestibule cupboard!!!

Anyone know if I can get BT to move this without an extortionate calling charge and I dont suppose I'll be getting 2MB with this results either.

I'm also getting a supposed 1152 kbps downstream, 288 kbps upstream from my router, but an online speed test of around 55 KB/s (which equates to approx a 512Kbps line) - I think this 2Mb speed is a myth :roll: ! I think it has nothing to do with the cabling or filters, but more to do with BT's line.

Thx mknash it worked !

Heres my results

WANCommonInterfaceConfig
DSLUptime= 651
ErrorredSeconds= 1
LossOfFraming= 1
LossOfLink= 0
LossOfSignal= 1
PhysicalLinkStatus= Up
ReceiveAttenuation_dB= 27
ReceiveMargin_dB= 26
RxOutputPower_dBm= 0
SendAttenuation_dB= 13
SendMargin_dB= 30
TotalBytesReceived= 7793438
TotalBytesSent= 11255663

TxOutputPower_dBm= 0
Uptime= 651
ChannelMode= Fast
Layer1DownstreamMaxBitRate= 2272000
Layer1UpstreamMaxBitRate= 288000
WANAccessType= DSL


I dont know what am looking for but I take it

ReceiveAttenuation_dB= 27
ReceiveMargin_dB= 26
SendAttenuation_dB= 13
SendMargin_dB= 30

This is the important stuff ? Are these figures good for 2 mb?



Anyhow I did the test and low and behold I suffer no disconnections once the Pcs connected directly to the master socket and I found a extenstion that oddly dont work directly in the socket... yet it works off another extention which is odd but ive chucked it now...

Using another cable heres hoping I dont suffer disconnections if I do its Wireless Router time and Goodbye £5 Clone BT Extention kits !

Good for 2Mb and beyond.
The required downstream attenuation for 2Mb is 43 Db or below, so 27 is fine.
And your SNR (Margin) is good too.

Thx good to hear that, my PC now remains connected all this all due to one iffy wire !

Id advise anyone also to go text book and try alternative wires/extenstions/pc next to master socket/another modem or router/microfilters....
