Hi,
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 all your applicable 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+).
Specs:
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:

You've identified a few issues that may or may not be related, you should try to tackle them separately:
1. Wireless issues
If only one of your clients is wireless, and experiencing the issues while others do not, you should try to change the wireless channel (do a wireless survey, use non-overlaping channels 1-6-11), make sure the wireless router is away from any possible sources of EMI, such as cable/dsl modems, power supplies, fluorescent lights, etc. Try to move the WAP closer to the client, boost signal level with third-party firmware or use stronger antennas.
Also, use WPA2/AES security and 20MHz channels if possible, it is most efficient.
2. Lag spikes
Are all clients experiencing them, or only the wireless one ? This is generally either an issue that will be resolved with the wireless problems, or it could be caused by your ISP. Traceroutes can help troubleshoot this.
3. Throughput (6 Mbps vs 2 Mbps)
Are the other two computers that are not slowed down wired ? If yes, this is likely connected with the wireless issues.
