Slow in Guildford

[wee willie]

I'm on the supposed 1.5mb service (213.107.72.***)
For the last 3 weeks its been really slow 128-200k
I put it down to this big upgrade

did the 'broadband medic' chat to a tech 3 nights ago and they diagnosed a cable fault in my area.
was told to give it 24hrs
gave it 36 and followed up with a 'real' tech support person
he just didnt have a clue

rang again the following day and got fobbed off again

rang this afternoon and spoke to a Karthik who seemed a step up from recent people
he emailed me some info on poor connections incl a link to Dan Ellwells speed test
Nearly fainted at paying £10
but surprise surprise it says I've got a very slow connection and should contact tech support.

Test 8: Download speeds from UK servers

Ideally, you should get a result of around 1024 Kb/s (higher is better)

mirror.ac.uk: 149 Kb/s

This result shows serious problems with your downloads, and should be investigated.

Test 9: Download speeds from European servers

Ideally, you should get a result of around 1024 Kb/s (higher is better)

heanet.ie: This test failed due to a server timeout or other error.

Too many server errors occurred therefore this test is inconclusive."

Now that seems like a few circles I've been round a few times

what should I do?

hi and :welcome: to the site , is this thru sacm or stb ??????? , can you tell us what tier you are on thru diagnostics ???????? :)

[wee willie]

its the standard cable modem

but I dont recognise your other acronyms

when you say standard cable modem do you mean the silver ntl badged type ??????? , stb = set top box :)

[wee willie]

silver, with the bit around the lights being black and marked ntlhome

[wee willie]

have now spoken to another tech at ntl

apparently they're all in india!
have they closed down the cardif office?

they say there's something wrong with my pc as a ping to the modem, disconnected from the pc, was much faster than pinging the pc ????

when the techs run their tools it may have shown latency on the PC but not on the modem. Indicating a possible problem with viruses, spyware, p2p (take your pick) or simply something installed on your PC using the connection. This is not conclusive proof in itself but a possible incicator of a problem.

start with the usual - full av scan using an up to date virus scanner, also try scanning for spyware. If you run p2p then make sure this is completely disabled.

i wouldn't recommend speed tests as such as they can be unreliable, there is however a good one on robin walkers site

http://homepage.ntlworld.com/robin.d.h.walker/speedtest.html

another good way of testing your connection is to try downloading a file from www.tucows.com using a good uk mirror.

After trying the advice from threadbare above you can also have a look the connection status yourself.

As you have the NTL Home Modem type this into the browser address bar -

http://192.168.100.1/

The user id and password will normally be - root and root

You can then if you wish post the results back here at the time the connection is failing/poor.

Ps I have asked a passing Mod to edit your IP from your first post as it is not a good idea to post your full IP address on a public forum.

fine, done using nod32
also try scanning for spyware.
did y/day with adaware and spybot, which I run frequently, nothing found

If you run p2p then make sure this is completely disabled.
stay clear of p2p

tried this
The connection is so slow, that after 5 mins, nod advised that there was a further estimated 40 mins to download, so posted back without this result

earlier this evening, I did an easynews trace, which showed speed less than 60 k

many thanks for your help guys

what do you think I should do now?

(now 1am uk time, will post back tomorrow)

Well I think you should give NTL another call as your Signal To Noise Ratio SNR is borderline at 23.68db coupled with the fact that your upstream power level shoud be closer to 40dbmv not 33.

[wee willie]

thanks carlingman for your help
I'll give them a call this lunchtime when it might be less busy

did a download from tucows uk
4.07mb in 23min 20sec ie 2.98kb/sec
this would normally have taken a few secs

[madder]

Im also in the guildford error and ther does sems to be a fault relating to the new servers they put in;

just look at that godamm ping 1200ms and thats good atm.. been high as 3000ms.. when u consider im like 3 miles from there servers.
Ntl should sort ther act out otherwise ill be swapping to 2mbit adsl as im only 1 mile from exchange p


hmm maybe its me.. well its ntls equipment so...

dBmvDownstream SNR : 23.68 dB <<< that is unacceptable, minimum specification for this is 24dB, and I mean minimum.

Upstream x-mit power is fine though. Enjoy the engineer's visit.

Yup, all fine, thanks.

Will check your modem when I have time, don't worry about giving me a MAC address the internal IP you've provided will be fine ;)

[madder]

a engineer did fit a filter on the line at 1 point when i was having dropout problems was later diagnosed as a chipset conflict usb vs amd and the ntl100 so i removed it.. me looks for filter lol

'80.4.30.149' was found in 3 hops (TTL=253). But, problems starting at hop 2 in network "(private use)" are causing IP packets to be dropped.

[wee willie]

eventually I got through to a second line engineer in cardif
he was particularly concerned with my fluctuating s/n and high pacet loss
and I will be having an engineer's vist in the near future

will post back

thanks for your help
wee willie

[wee willie]

have had the engineer round
he found no fault at my site but concluded there was a network fault

the network engineer came out on thursday, cleaned the connectors for a slight snr improvement and detected faults up the network.

As of tonight, friday, my speeds are now @ 700k, very much better than before, but a long way short of 1.5mb
how do I progress with the network engineer/fault dept, no one has given me any contact details

[wee willie]

I've been in touch with engineers today
snr still 23-26
they insist there arent any network problems
did a download test from tucows whilst they were on the phone and obtained 84 Kb/s whereas they said I should be on 177/187
hence half of my supposed 1.5mb bandwidth
there was only 22% utilisation on the line
they say there may be a '10% loss due to my pc'
where they get there info from I am unsure

contacted my network support company and he disagrees that there is anything here causing a problem

how do I fix this?

answers on a postcard...............

when you say network support company , what exactly do you mean by that ????? :)

[~Dan~]

Have you tried using a different webcache?

[wee willie]

when you say network support company , what exactly do you mean by that ????? :)
I had a network consultancy set up my husband and wife network cause its beyond my tech capability.

I referred to them today to see if there was any validity in ntl's ascertions that my setup was causing a slow down

[wee willie]

Have you tried using a different webcache?
Dan

I'll give that a go tomorrow, but 99 ntl tech's so far have never suggested it

[wee willie]

the cach change didn't have any effect


after the ntl network work was done I was able to get occasional speeds of 100k
but my dan ewells speed test show 750 nto 1500 download speeds (excuse my lack of knowledge re the units)

but I also seem to have more than my fare share of packet loss

when I've got some time to spare I'll persevere with ntl's tech support again

[wee willie]

Finally had the matter solved and for the first time I have 1.5mb speeds

the engineer was very good
he found that when ntl changed out my old cmx modem, they didnt change the power supply, which effectively fried the new modem
this was replaced as was the ps
o/side, the box was letting in water
which the engineer has asked to be fixed
(the previous engineer, 2 wks ago said similar things, but nothing happened)
will keep my fingers crossed
the previous engineer did put in a new cable connector BUT he inserted into a naff/rusty part of the box

low and behold
new modem + psupply
new connector housed properly and voila all finally solved

its taken c 2 months to sort this
