Hi there.

The wifi kicks in an out every 15-30 minutes, and it's driving me insane.

80K90011US

Preinstalled Windows 10 (When I do auto-detect on Lenovo's site it only offeres me windows 7 and 8 as options. Why is the computer installed to 10?)

If you need any other numbers to assist, please let me know.

I saw some posts indicated a BIOS update, but would appreciate the confirmation which one I should be using, if in fact that's the issue. 

Really just bought a few months ago, so hoping this isn't a long-term issue.

Thanks.
