Have I been downgraded ?
 

Last few days my broadband service (600kbit) has been really eratic. Not reliable at all.

Then today it seems to have gone really bad, so I did some tests.

I'm doing a download from microsoft and getting just over 18KB/s which is suspiciously like 150kbit service speed.:Yikes:

Is it likely that I have randomly been downgraded for no reason ? Or is there some other problem with the network at the moment. (walthamstow).

My response times are pathetic :

hi and :welcome: to the site , have you tried powering down the modem for a while to see if it cures it , depending on the modem you could try docsdiag to see if you can see what service level you are on :)

Hi ntl.wotcha & welcome to the site. :welcome:

Visit this speed test and post the results below. Thanks.

Re: Have I been downgraded ?
 

Looks like a oversubscribed upstream causing that, or poor signal. Call TS once you've eliminated your PC.

Re: Have I been downgraded ?
 

Check that there are no peer to peer programs (e.g. Kazaa) running in the background as they can often saturate the upload channel if you leave your files to be shared.

Go to http://192.168.100.1/P_log.htm

The password to enter is usually root and user is root

Look out for something a line "ntlhm120-silver.cm" in one of the cells in the table. The name may vary but the service levels AIUI are..

Bronze - 150k

Silver - 600k

Gold - 1Mb

Re: Have I been downgraded ?
 

The speed test Mick asked you to run would be a useful indicator - but you problem looks very close to home since your trace from the ubr onwards is poor. What is your home set-up ?

Re: Have I been downgraded ?
 

...or you could go to the root page http://192.168.100.1 and click on 'operation configuration'. The 'Maximum downstream data rate' should show 600000 bps.

Re: Have I been downgraded ?
 

Ok, so i;ve been trying to connect to 192.168.0.1, but just get timed-out. PC is connected to CM via ethernet. Any ideas anyone?

Re: Have I been downgraded ?
 

what cable modem do you have?

Re: Have I been downgraded ?
 

192.168.100.1 is usually the address - what type of CM do you have ?

Re: Have I been downgraded ?
 

It's a 200.

Re: Have I been downgraded ?
 

That's what I get if I have a specific proxy specified, have to clear the proxy settings to get to the 192.168.0.1

Tried the speed test... odd results...

Mon, 3 May 2004 21:36:46 UTC
1st 128K took 3094 ms = 42363 Bytes/sec = approx 352 kbits/sec
2nd 128K took 2914 ms = 44980 Bytes/sec = approx 374 kbits/sec
3rd 128K took 2384 ms = 54980 Bytes/sec = approx 457 kbits/sec
4th 128K took 3204 ms = 40909 Bytes/sec = approx 340 kbits/sec

Not 150k but not 600 either !?

I generally find speed tests are a bit flaky, which I why I use the win2k sp4 download as it consistently will serve well over 2mbps.

Go to http://192.168.100.1/P_log.htm

No response. (I don't have a proxy set).

I've got a STB CM. 2000 model ? not entirely sure.

How do I do docsdiag ?

My PC is plain ethernet into the STB. I've got nothing running on the PC, first thing I did was shut everything down !!!

So if it's not my service level or STB ? It was really bad this afternoon and isn't much better now :(

Re: Have I been downgraded ?
 

Because you have an STB you will not be able to view any diagnostics on 192.168.100.1, nor will you be able to use DocsDiag. You can view the signal level data on your TV screen: see http://homepage.ntlworld.com/robin.d....html#pacediag for details.

Your problem might be related to signal level problems, but in your original post, if those traceroute figures were taken at the same time as doing a download, then the traceroute results are invalid as far as the round-trip times are concerned.

Re: Have I been downgraded ?
 

Yep, a slow running 600k. That speedtest is very reliable (I have tested lines above 25Mbps on it - certainly more reliable than pulling a file across the pond, and using the speed as calculated by IE ;))

Are you sure nothing is eating bandwidth on your PC ? - a simple test is to close down everything you think is using the net and then go into network connections and double click on the LAN connection. The send/receive activity counters should remain steady (i.e. no network activity). If they are still clocking up packets/bytes then something on your pc is still using the connection - and is probably the cause of your problems.
