Augustus, can you tell from a trace route?

(this is the game server which pings 69ms from the command line yet gives pings in-game of 300 plus without fail, every time. So the fact the command line ping is decent, is a red herring.)
 
Looking at the first hop a quick google throws up murphx who are a reseller. Then goes by carrier to a german IP, then an IP registered in usa, then sweden then norway. Most of the latency in that traceroute is occuring between german and american ones. It's why it's routing via america that's the question.

It's bad enough that your traffic is routing via america on a ping.....remember that if it is traffic (gaming) then you will end up as best efforts unless your ISP guarantees priority traffic.

Looking at that ping you'd be better joining a server in america!

You should only need a single thread to max your line if you use a local server (assuming it has sufficient bandwidth). Only with a poor ISP do you need more.

True enough you should be able to max your connection with a decent server, but my point was when you get people complaining they only get 7mb speeds when syncing at 12 for example, I wonder how they are testing. In my opinion if you want to max out your connection to test how quick it is at max throughput you should do everything you can to make sure nothing else in the loop is effecting the speed. Hence saying use multiple connections to a good server, you have the best chance to max out your connection without the server being the bottle neck.

"Only with a poor ISP do you need more" hmmm not sure what you mean here, it's all to do with the bandwidth available from the server, if your ISP is poo, making multiple connection or just one will show the same results.
 
Don't do it! Terrible performance since switching.

I've gone through the effort of registering on this forum just to warn everyone currently on adsl24 to not switch to the so-called C&W LLU service. It's terrible.

I had no problems on the old adsl entanet circuit but thought I'd give adsl2+ a go. I checked with them first that my router would be compatible and was told it should be fine. As it is I've had a week of disconnects, lost packets and aal5 errors which mostly seem to be due to a terrible noise margin. This is the same line that had great stability on entanet so I know it's not a line problem. Every time I have to shut, no shut the atm interface or reload the router.

Not only that but when it does connect the sync speed is only marginally higher and the actual download performance is worse. It would appear that this service has very little to do with C&W at all, actually it's going through murphx who describe themselves as tier 1 but I have my doubts, a linux cluster and a couple of Cisco's running glbp do not make you tier 1!

To top it all off I raised a ticket with them and asked to be switched back but was told it would cost £46. Nowhere in the conditions I looked at did it mention this. Not good customer service.

So now I'm stuck on a barely working service and have just reloaded my router to get 5 minutes to warn you all - don't switch! Think I'll post this on thinkbroadband as well.

Regards,
 
Just a heads up -
After changing over to ADSL24 LLU, I had 2 days where my service was almost unusable. I had frequent disconnections and my router often took some time to work again (re-sync?).
However - Its been fine since monday, stable and as fast as I was told it would be for me. Gaming pings have increased but only by around 5ms and I hope to have fastpath put back on soon. So it's worth considering.
Changing your line to a more demanding service, plus C+W being fairly new, was always likely to mean the service might not be perfect from the start.
But worst case scenario, you get your line upgraded for free before moving to Be ;)

Not everyone lives in a Be area (something many fail to grasp) including me.

Worst case scenario is having to pay £46 to return to the BT network to get a fully functional service.
 
Fair point. But I noticed that Be only became available to me after my exchange supported LLU so I assumed there was a direct connection.
If theres not, be ( ;) ) sure to check your area! :)
 
Ahhhh so there is a reason that the C&W LLU is cheaper than the BE LLU through ADSL24. I'm on the BE LLU and can't complain at all about the service, uptime, speeds or gaming pings. Everything has been first rate.
 
An old ADSL one, but which was perfect on the BT network (Entanet) and is not the cause of my high pings on the server I posted about.
 
LLU networks are highly sensitive to the type of router you are running. I upgraded from an old Zyxel Prestige 660HW to a new Netgear DGN2000 and got a huge boost in speeds and stability from a very long line (>7KM) Went from 1500Kbps to 2800Kbps in my case. Been rock solid ever since.

There is a page on the ADSL24 website that goes through which routers you can use with LLU and which the best ones are. The link is:

Nothing wrong with speeds and stability here, it is a fine router. The pings to that server are down to a problem with the C&W (or murphx??) network. Others have posted about issues who are using ADSL24 'recommended' ADSL2+ routers so it's a red herring to blame the router for this.
 
I don't suppose you have UT2004 installed do you? Firing that up and going to the same server where I'm getting pings in the several hundred, would be the acid test because it usually pings fine from the command line.
 
it's interesting to see some of your experiences with the C&W LLU service. I previously posted about the success I had when I switched but I recently switched a second line and have had nothing but trouble.

As has been mentioned by others, my stable connection became very unstable and at times unusable. Restarting the interface was often needed to get things going again. After 3-4 days of trouble interleaving was turned on but I was only able to connect using ADSL1, it was stable and slow however that didn't last long as the connection died completely a couple of days later. After almost 48 hours without any connection the port I was on at the exchange was switched but the instability remained.

I'm not sure what the problem is because I had no trouble with an almost identical set up (same firmware, ISP, router config).

Site A, Cisco 877:
BT ADSL2+ (IFTN (Huawei) hardware in exchange) = lower than expected performace*
CW LLU ADSL2+ (STMI hardware in exchange) = good speeds

Site B, Cisco 857:
BT ADSL2+ (IFTN (Huawei) hardware in exchange) = lower than expected performace*
CW LLU ADSL2+ (STMI hardware in exchange) = unstable connection, poor speeds.

I know it isn't the router as I've tried the 877 in site B and it had the same trouble as the 857. It got to the stage where I've had to request reverting to the BT service.

*in June there was a firmware update on IFTN-based hardware in BT exchanges that has hindered ADSL2+ performance with certain cisco routers.
 
Hmm , this does seem odd, so far I have had much better connection and speed through the C&W LLU than I had with the BT whole set up from ADSL24. I guess its as much the gear in the exchange and what it hooks up to as much as it is from the exchange to your computer. Are site A and B in the same area ?
 
Dirty, I am in an unfortunate between PC builds situation at the moment and only have a poo toshy laptop, so no games installed. Not sure what else we can try other than command line pinging, or I could install steam and see what I get to the servers through that ?
