Belkin F5D9050 Driver Issues  

Sold the adapter, will be staying away from Belkin products from now on.

I have this Belkin wireless adapter, F5D9050 Version 3002, which I successfully used with the Win7 release candidate with a driver I downloaded from Ralink. When I decided to install the retail release of Win7 Pro, that same driver failed to work. When I say failed, I mean as in running the driver installation file and the adapter being udpated and ready to use. Now, here is the file I currently have, but unfortunately I do not remember if this was the same or a more recent driver I obtained from Ralink:

IS_AP_STA_RT7x_D-1.3.5.0_VA-3.1.7.0_W7-4.0.3.0_RU-3.1.2.0_AU-3.0.3.0_082409_1.5.4.0_Free.exe

From that long name, I assume this means it is version 3.1.7.0 for Windows 7. I may have found, downloaded, and installed this driver when I first discovered the retail Win7 release wasn't working with the adapter. Regardless of that, the installer still didn't work, yet I took the same sort of approach as described by Stephenishere in post #6. That is, from Device Manager, I opened the properties for the invalid device and updated the driver by navigating to the list of manufacturers for Network Adapters, choosing Belkin, and - I'm pretty certain - the Belkin Wireless G USB Adapater. Windows 7 detected the driver that way and my adapter worked fine. However, in a subsequent Windows Update, a different driver was automatically found and updated. The device identification in Device Manager is now "Belkin Wireless G Plus MIMO USB Network Adapter", and it appears the driver may actually be older than what I was using, judging from a version number of 3.1.2.0 dated 11/12/2007. The adapter works like a champ for me, although sometimes it is lost upon connecting another USB device, which seems to be some sort of USB limitation on my system. When that occurs, I simply unplug/replug the adapter from its stand, and it gets reconnected and restored with all functionality.

I've done everything you have and I was still having the problem I described. I think it may be a problem with my XPS 8000 rather than the adapter. The sad thing is that my XPS is barely 2 weeks old!

Thank you! Now my Belkin F5D9050 is working with my Windows 7 64-bit..Thanks a lot!

Stephenishere, I also signed up just to say thank you!!! for posting the solution. I followed your instructions and it is now working!

Thank you also bojackson63044 and Stephenishere. Mine is the F5D9050C version 4. The info was invaluable.
Stephenishere's step by steps were spot on. I'm new to Windows 7 and the internet is up and running.... will it be spotty?? maybe, but for now I can finish setting up all my basics. Thank you!!! Thank you!!!

Since this is the first hit on Google, I wanted to update the thread and let passersby know that Ralink was purchased by MediaTek in 2011 so the provided links to Ralink no longer work. You most likely need the driver for RT2671 if you have a v3xxx or v4xxx adapter. According to https://wikidevi.com/wiki/Belkin_F5D9050_v3 and https://wikidevi.com/wiki/Belkin_F5D9050_v4 these models only ever used the RT2671 chip. I was a little confused by those pages saying that they had a second chip (RT2528), but if you look at https://wikidevi.com/wiki/Ralink and search for RT2671 it seems like the RT2671 always uses the RT2528 as its secondary, so no need to find the driver for that one.

Anyway, I installed the driver and did still have to use the manual selection method that Stephenishere detailed. I used the first Ralink Technology Corp. entry (the one without the comma) and selected the one listed as "802.11b/g USB Turbo Wireless Adapter (Ralink)". Everything seems to be working well here. This adapter is old as dirt, but hey - it still does the job when speed isn't critical.

Thanks soydeedo, your post was correct on all counts. Using archive.org I was able to confirm that the release you mentioned (2K/XP:1.3.5.0, Vista:3.1.7.0, Win7:4.0.3.0, dated 08/24/2009) is the latest one. The page also indicates the drivers are 64-bit compatible for XP/Vista/7.

Unfortunately Mediatek has now removed all downloads for these chips (RT257x /RT2671 /RT520x). If anyone in the future needs the installer, searching for "RT2671 4.0.3.0" should lead you there. I grabbed it from the following site: RT2671 @ TousLesDrivers.com
