My media center machine is my guinea pig. It’s relatively old with it’s nForce 440 based motherboard, Athlon 64 3200+ (Socket 989), and 1 whopping gig of memory. It’s also got a Hauppauge MCE500 dual analog tuner and an ATI 4550 with HDMI out to my Samsumg A550 40″ LCD.
I couldn’t be happier with how Windows 7 performs with minimal hardware. This machine is easily 3.5 years old, and it wasn’t exactly top of the line when I bought it. H.264 at 1080P plays flawlessly (thanks to AVIVO), and the Media Center interface is incredibly responsive, even right after bootup (which, I’m sad to say, wasn’t the case with Vista).
Anyway, last night I reinstalled Windows 7 Beta x64. Every single driver installed out of the box…except this damn WMP54G, which also didn’t work on Vista 64. So, here’s how to make it work.
This card is based on a card by RALink…that, or they use the same chip. Either way, they offer a driver that works.

I downloaded the RT2500 installer. Then I installed it. Here’s the direct link.
So, install then, then head over to Device Manager. You should see this:

Double click that device and go to Update Driver.

Select Browse my computer for driver software
At the bottom, select “Let me pick from a list of drivers on my computer”
In the next window, scroll down to Network Adapters and double click. Then click “Have Disk”
In the box that pops up, navigate to/enter this path: C:\Program Files (x86)\RALINK\RT6x Wireless LAN Card\Driver
Hit OK then scroll down to “Ralink Technology Corp” in the box on the left side. On the right side, select “802.11b/g Wireless Adapter.”

Click YES on the warning.

Success! Now try to connect to your wireless network.



At first none of these things worked, what I had to do was SKIP the click “have disk” step and select Ralink > 802.11g Wireless PCI Adaptor, and it finally worked! Thanks for the help everyone
If you are getting a code 10 when trying to install the wireless drivers do the following.
1. Remove the wireless card from the PC.
2. Remove all network adapter drivers.
3. Install the device drivers as above.
4. Update the device drivers as above.
It worked for me on my PC, hopefully it will work for you too.
I just LUV UUUUUUUUU
tnx alooooooooooooot
peace out !!
Found it !
After 2 days reading and trying, I finally found the trick.
When installing the driver you must choose the Ralink wireless pci card (AS DESCRIBED ABOVE) but when it comes to the I HAVE A DISK option you must search for the conceptronics 54 G WIRELESS CARD drivers. Windows will automatically install the conceptonic driver.
PD: I tried to install directly the conceptronics drivers but didnt worked at all.
After 2 days worked for me!
