In the absence of line stats, which you have, and the results of a BT speed test as someone requested, I would say those figures show a line fault, or if you are running wireless a serious problem there.

I find it almost inpossible to believe those results are simple congestion.

Start by running a Traceroute to BBC.co.uk

Then use the TBB incoming Traceroute tool: http://www.thinkbroadband.com/tools/traceroute.html

Post both results here.


Do you loose sync? If not, use the TBB BroadbandQuality Monitor on your current IP for an hour or two and post a link to the resulting graph. Remember to go and turn it off later or whoever gets your IP next will be pestered by pings and te results meaningless.

My line is fine, and I don't use wifi at all. I have a gigabit switch, a gigabit-based Routerboard 750G, and the Huawei modem

I've started a monitor, I'll wait an hour and see what it shows... Thanks for the tip actualy, now /that/ is useful information!
Note that it appears the congestion is "reasonable" and constant on a few routes (I get about 23Mb/s on "uncommon" servers at the minute, like france, gloucester, ashford etc) but it's /horrible/ on more local places, like maidenhead and any of the London servers.
So it might be that I'm sitting one [censored] 21N segment.. the problem is, most traffic goes thru it, and it makes even web browsing laggy!

It seems there is no technical problem then, and as only you are reporting this shocking level of service the only possible conclusion is that you have been singled out by BT as someone to hate and throttle. Nobody else with a fault-free line has experienced this.

Why don't you want to supply any data that anyone asks for? Why are you posting here at all except for fun? You clearly don't want any help, as you are absolutely convinced that it is congestion.

Your only solution seems to be to move house and/or migrate to a new ISP.

You could of course demand to be released from your contract, and fight that through the disputes procedure and OTELO, perhaps ending up taking them to court. Enjoy .

Where are you - geographically?

I can get >32Mbps from almost any UK server on speedtest.net and similarly around Europe or worldwide. Except - Maidenhead which gives 2.56 Mbps compared to 36+ for London and Newbury.

If you can get the IP address of a server used for speedtest.net and see what a traceroute to that gives - a full trace not just a ping.

Well,
+ I work from home, and most of the day most tests report ~38/~8
+ I don't download torrents, games, usenet or whatever
+ I have a core i7 at 3.8Ghz with 16GB ram, running linux
+ All gigabit LAN, jumbo frames where possible. Wifi is on a DMZ just for the iphone/pad, idle.
+ Unlocked Huwai, mounted on a special vented metal shelf so it doesn't overheat.

+ I've been writing network software before most people had even seen an ethernet cable let alone heard of "internet", in fact I was writing tcp/ip stuff before the web existed, since I never stopped doing so, I tend to have a vague idea about it all.

+ Problem happens only at peak hours, and seemingly only on some (key) segments that happens to be /outside of my house/ strangely enough.

+ I've actually heard of people (not the fanboy kind that you appear to be) going to that contract cancellation phase on BT Infinity for the same sort of reasons.

nice CV

I gather you consider me an Infinity fanboy? Please clarify if you wish, as with your connection behaving as it is you must have plenty of time so to do .

Though why you are posting here is indeed baffling given your detailed self-description. You know very well there is nothing to be done except get a non-BT Wholesale connection.

I'm in Windsor, Berks. I'm also starting to have doubts about the Maidenhead server, and possibly the "London" one (TranceFM) too...
I've just done a few other tests on other peripheral servers and they mostly report ~25Mb/s down now, so the problem appears to clear up -- to me that's pretty much "acceptable" peak time performance too...

Here's the last test, using Newbury.

I'll setup a packet sniffer to see if I can pick the speedtest server IPs, I'm curious to see if there is some sort of route blip on them, or if it's (possibly) these particular server that are slow. That wouldn't help my "generally very laggy" browsing if it was tho..
