I'm based in South Manchester (Stockport to be more precise)

Bolsch the speed is in kbits and should be 10 000.

You MTU is wrong, it should be 1500.

Your RWIN should be between 94500 and 250740.

If you download drtcp on the site you can correct that.

Indeed, that looks an awful lot like some weird windows dialup tweaker.

Try my settings:

MTU is 1500.

1. Your Tweakable Settings:
Receive Window (RWIN): 189800
Window Scaling: 2
Path MTU Discovery: ON
RFC1323 Window Scaling: ON
RFC1323 Time Stamping: OFF
Selective Acks: ON
MSS requested: 1460

Ignition how did you come to 189800 for your rwin? used dsltweaks formula?

The problem I found is and they even mention this, a higher rwin is good when there is no saturation, but I found that in the evenings when downloads often stall due to retransmissions it has to retransmit a larger amount causing the stalls to be longer.

Tried those settings, actually made it worse. http://www.adslguide.org.uk/tools/sp...424b27fd132bd9 and the speed test on this site now crashes Firefox and times out in IE lol

Kev gave me a couple of proxies to try. 2 gave 404's the other worked but gave me same speeds. I've just tried ftping on Kevs recommendation and ftp speeds to be ok. From my domain got speeds of 350kbps and from debian.org got 1200kbps.

Just a thought, as im running a bit low on ideas. Forget about your PC, thats not it (unless your Sun Sparc, apple mac and X-box all have the same issue).

Try browsing via IP address. Does this make any difference to the HTTP speed??

charliep · 15-03-2006, 11:41

I am in south Manchester on a 1meg NTL STB connection. Been suffering 'dial-up' performance since last Wednesday. Already removed my router from the eqation. Still get 130KB/sec download from a few sites but mostly get 2-3KB/sec or pages time out.

Rone · 15-03-2006, 11:49

Ditto, its pointless sending out engineers to homes, its more widespread.

They all have the same problem, no difference browsing my ip

I've hit 10mb downloads once or twice in the last week (most notibly from Apple's trailer site, but not all trailers come at 10 probably 1 out of every 15 the other 14 are creakingly slow.

KevAmiga · 15-03-2006, 12:03

Right... im away from my desk for a while but i have been emailing back and forth, ill paste some stuff here for others to look at and ill check back later.

Odd... seems to be a traffic-issue... ill take another look later.

You really need to try larger pings. If there's a device with a duplex error somewhere in the network then small pings will often get through, but large ones wont.

Work your way down the tracert hitting each with large pings and see which one starts to drop packets.

Rob, a quick tip. I have found people are more likely to be helpful if you are polite.

The NTL staff who help on this site are not paid to do so. It is not part of their job to help on this site.

You'll also find when phoning any call centre (be it Tech Support, Customer Services or whatever), the operator will be more inclined to try harder to help if you are polite.

I am not having a go, as it is entirely possible you meant Tech Support anyway.

15-03-2006, 14:21

Hey just be thankfull, you may have been on the phone for an hour this time but at least the call was free. Won't be long before you will be paying 10p per min for the call! That call could have cost you ÃƒÆ’Ã†â€™ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£6.00

Robjones23 · 15-03-2006, 16:31

Guys,

firstly, apologies for last night's tirade, I was ****ed off and it didn't help coming here to see people recommending using proxies yet again.

Secondly, from what I can tell tehre are a lot of problems in my area, Baz has posted another thread "help" and he's in the same postcode region as I am (SK8 3) so I'm guessing we must be close to each other.

There must be some way of getting the kit checked out that we're connecting through and I don't mean our STB's / SACM's. Mine works fine when I go via a proxy (will post the proxies I have for those who are having difficulties when I get home) but going via a proxy is useless for anything other than surfing the web.

Oh, forgot to mention that NTL ahd also managed to setup another direct debit from my account and I've been paying them twice each month for the past 5 months. When I called up regarding that they didn't know how it could have happened!!!

bah - rant over and apologies again to those I offended.

---------- Post added at 16:31 ---------- Previous post was at 16:30 ----------

oh and I called an 0845 number which isn't free, and i called from a mobile

KevAmiga · 15-03-2006, 16:34

No worries.

Maybe one of the mods can attract some attention via Responsetek?

endoftether · 15-03-2006, 16:48

I am also in south Manchester (Sale) on a 1meg NTL broadband connection. Been suffering 'dial-up' type performance for 3 weeks. Mostly get 2-3KB/sec or pages time out.
Engineer has now changed my cable modem but the connection speed is even worse! Call centre staff are not very helpful - if I change supplier will this solve my problem?
Please help me!!!
