Hi,

I've been getting significantly higher ping in-game lately and it was fine a week ago. I was usually sitting at 30-40ms. For the past several days, its been hovering at just over 100 and goes much higher during raids (up to 150-200). Here is a test I just ran:

The latency even happens at very early times (today it was as early as 9am). Speedtest.net and pingtest.net both report sub-20ms ping and my usual, expected download and upload speeds.

As the title mentions, I am on Virgin Media National in the UK and both their forums and service status pages don't report any problems right now.

- I am on Windows 7 64bit, with the 64bit WoW client
- I have tried running without addons and I have deleted my cache folder
- I have not installed any new drivers for my network adapter or any hardware lately
- I do not have any background applications running other than Google Chrome
- I have tried setting the MTU to 1458, 1492 and 1500 along with rebooting my router and my PC
- I have always been on a wired connection
- I have tried setting the "Optimize Network for Speed" setting on and off, no difference
- I have made characters on the Karazhan, Spinebreaker and Kor'gall realms and the latency is roughly the same
- I have tried playing some other games, including League of Legends and Battlefield 3 and I was getting 30-50ms.
- I have tried another router - a Linksys WAG120N.
- The firmware on my current router cannot be updated as it is a specially modified one from the ISP.
- I have tried turning on and off the TcpAckFrequency trick and the ping was higher without it
- I have tried disabling all firewalls and protection features on my router as well as the windows one. I do not use any antivirus software.
