world of tanks still unplayable

[#1]

five days ive tryed to play this game and its useless ping jumps 999 then back to 30 -40 then 999 then dead i just cant play it
rang lots of times, they say your speed and connections are fine which is true, but its the ping spikes packet loss all the time
i have tryed everything i no on my side and changed everything turned windows and router firewall off makes no difference still the same

Have you considered setting up a ThinkBroadband Broadband Quality Monitor to graph your line's ping performance ?
Have you had your upload speed uncapped ? - as slow upload speed can cause ping spikes if the upstream path saturates.

yes upload as been uncapped will try the other

@gary12345
I'd agree from looking at recent fault tickets that the connection seems to be stable again and that speeds have recovered.
If you could give the TBB monitor a go as suggested, also assuming you use windows performing a pathping in a command prompt when the issue is evident could be of help too.
