For the last couple of weeks, i've had rubbish speed on my pc when connected to wireless. Used to get around 6Mbps bandwidth but this has decreased to around 2Mbs.
I have 2 other machines (i have not tampered with :/) on the same network which perform fine (around 6Mbps).
I tried several 'Speedguide' tweaks (including Nagle algorythm tweak) but get varying speeds and 'rubberbanding' when playing games online (BF3) and huge lag spikes (from around 40ms up to 1000+).
Win 7 Home Premium, Intel i7 2600k @ 3.4gh
Netgear DG834G v4
BIOS, router firmware and all drivers
are up to date.
Please find below my analyser results:
