W7 64-bit Internet bandwidth loss. SMC Driver Issue?!

Please help me out here. I have a desktop with wireless access thourgh a USB wireless card (SMCWUSB-G)

I don't know what else to do. I have tried everything. I have searched around in forums, asked people...I need an internet expert.

I have a 20Mb internet plan but after swtiching from Windows 7 32-bit to Windows 7 64-bit i dont get more than 2Mb, normally only 1Mb. Plus now my signal is weaker, i'm only getting 2 bars out of five when i used to get 3 or 4.

My download speeds don't get passed 30kb/s and i lose connection all the time now. I can say its not the distance from the router. This is driving me crazy!!

Here is what i have tried to solve it:

- DOS command: "netsh int tcp set global autotuninglevel=disabled"
- TCPOptizmier: gotten only worse and i think it was when my signal started to get weaker.
- Disaled IPv6 in internet options
- Disabled QoS

Forgot to mention that the driver that came with the SMCWUSB-G wouldn't work with the 64-bit. I would install it and still windows wouldn't recognize my wireless adapter. I could manage to make it recognize by intasliing an older version of the same driver (i think) in the same folder as the one that came with the CD.
