Latency Problems
Hi, I'm having a few problems with my internet connection at the moment and getting constant packet loss to servers on unreal tournament 2004. I've been doing tests for the last few days to try and see where the problem may be and I'm pretty sure it's not at my end.
When I check pingtest.net the results are usually very good with low ping, jitter and no packet loss (most of the time) but further tests show high pings and packet loss through hops to plus.net before reaching the final server.
It will be a lot easier to just show the results below...
This first image shows a tracert to the ip for a game server I regularly play on and shows a star at second hop, which I believe is packet loss?
This is a test using winMTR to continuously ping to the server and at the 3 plus.net hops the worst ping times are very high. Although no packet loss is shown in this test, I have repeated it a few times and there has been some.
Finally I tested wireshark while I connected to the server and as you can see the differentiated services field shows 0x00
It seems weird that pingtest is fine 99% of the time even when testing servers to other european countries but every server I join in ut2004 has packet loss. Maybe It's the server? But the results above suggest a problem with plus.net
Here is the stats from my router.
DSL Downstream Rate: 12641 Kbps
Down up
DSL Noise Margin: 4.1 dB 27.0 dB
DSL Attenuation: 30.5 dB 15.6 dB
If anyone could help it would be greatly appreciated.
Thanks

Taking a gander here... http://community.plus.net/library/faults/using-wireshark-for-data-capture/#queues
You'll see that a 0x00 is bad. as thats bronze, gaming should be higher up the priority then that.
Does the server use a non-standard port? this could be the issue.
The "packet loss" you talk of is nothing to worry about, if you see no responses by PN kit - or its very slow, this is pretty normal.
Cisco kit (for example) puts responding to pings very low priority, and transferring data as very high.. So that people pinging it doesnt affect its performance (pretty clever really ::))
Thats why you sometimes see spikes on the tracert. as long as your not getting loss to the destination - you should be good

Sorry to be very un-descriptive, but that thread is at the top of THIS forum, and explains how to sort out issues like this
*Snip* from the PN Customer Support Traffic Shaping Pages...
Another option is to add the "PRO" addon, which will prevent anything being 'shaped' (dependant on your product its a £5 addon).
However, as you say its happening in COD, i'd say something is awry here..
Can you check what it says next to "VP Capacity" when you look up your exchange Here - Exchange status
What Router do you have? are you going in over wireless? there are many things which could add latency, please elaborate

Quote Some applications not using the standard port may not be identified correctly by our system, as we use DPI to identify applications on the network. These applications may be classified as 'other' traffic in which case a lower priority may apply.

Seems I have been paying for the pro addon and Plusnet didn't activate it at all!
