Cutting to the chase: Agree with all who say Atheros 5700 driver works! After 2 days of grief, I finally downloaded the 5700 driver and my Lenovo/Vista laptop is back online!
If you've tried everything else, and have visited the Atheros .cz website but just haven't trusted it, you are just like me.
I tried everything in this thread...more than once, and like so many others have written, nothing worked. Finally, and feeling that I had nothing left to lose, I downloaded the 9.1.0.328 driver at the link in Bushwhack's post and updated my Lenovo's 11 a/b/g
Mini PCI Express Adapter and the problem was immediately solved!
Things I was concerned about:
- Atheros.cz website appears extremely "unofficial"
- Hard to figure out exactly how to download the driver from the website (keep trying!)
- Windows kept telling me my Mini PCI Express Adapter driver was already up to date (but apparently it wasn't!)
- The driver description on the .cz website didn't appear to exactly match my Mini PCI Express Adapter. My device manager did not tell me exactly which Atheros chipset I have....just said Mini PCI Express Adapter
Again...after trying literally everything in this thread multiple times...I felt I had nothing left to lose....but this driver did the trick for me!
I hope this post can help keep others from wasting countless hours with other fixes that may not work...and also keep you from worrying about the things that I worried about. Thanks to all those who previously endorsed the Atheros.cz download.
