WLAN having consistant high latency with frequent all-out fail

My previous problem started with a wireless N router that would crash when more than 3 computers were wirelessly connected. Just purchased a new and better wireless G netgear router that works like a charm, for all 6 other XP computers except my vista machine. This shows that it's not a network or a router problem, but it's infact this machine I am on. Ran a few simple troubleshooting tricks but the one through cmd.exe says all I need to say. Just ran a simple command; "ping -t 192.168.1.1" under administrator. All I did was ping the wireless router. Let the result speak for themselves...

Ping statistics for 192.168.1.1:
Packets: Sent = 614, Received = 493, Lost = 121 (19% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 3991ms, Average = 614ms

In reading other threads I need to mention that this is NOT THE LAG SPIKE ISSUE in most vista machines, caused by the maching looking for a better signal every 60 seconds.
Here's a list of things that I have triple checked...
-Firmware
-Drivers
-Hardware drivers
-Dhcp flagging
-CPU (ping command was ran while system was idle)
-Ipv6, network discovery and media sharing are OFF
-No lightning storm =)

Is there a known virus that causes this? Reminder, I've done enough troubleshooting to ensure that this is my individual Vista home 32-bit machine that has the issue. Every other maching was returning a ping response in <1ms and mine were averaging almost 600ms.

And there have been moments when both my CPU cores would spike to 100%, sound and mouse movement become choppy, then complete disconnect. I have to reset my wireless switch on/off to regain connection.///// It's also worth mentioning that every time this happens, my new ip address will be a higher number.\\\\\ EG -> 192.168.1.8 before disconnect then becomes 192.168.1.9 after hardware reset. Im at .14 now.
