So I live in Melbourne, Victoria, Australia and I just got a new computer and awesome new internet plan + modem and the other day I got Battlefield 3 for my PC (specs below), it was all fine for about a week and for the past few days it has all gone to s**t.
At first I couldn't join any games so I went to my services and disabled SSDP Recovery and UPnP Device Host as well as UPnP on my routers settings (Netgear CG3000 modem-router) and it was all working perfectly.
My latency has gone ballistic on Battlefield 3 at around 200-950ms from my usual 20-35ms and this is all on Australian servers. I have tried re enabling and disabling the services and UPnP but nothing is working at the moment. My networking is fine and so is my internet for everything except BF3.
I used to have a wireless range extender for my network and I gave it the name: OPTUSV93EAB0_EXT after my router's SSID (OPTUSV93EAB0) but now It is packed away in my desk. I had My desktop computer connected through the range extender for a short period of time (maybe 2-3 days) and because I wast satisfied with my connection, I went for cable and picked up two dlink dwp307av powerline adapters and since I have had them hooked up (connected directly to my router and then to my Computer has named its connection OPTUSV93EAB0_EXT for no apparent reason and I cant change it, I have had no networking problem other than with Battlefield 3. My range extender is the WN2000RPT.
