my y410p😢

I've had zero issues on my Y580 with Win10. In fact, a lot better compared to Win8.1... Try to get latest wifi driver from Lenovo or from the chip provider (it's either Intel or Broadcom IINM)

Perhaps u try to uninstall the residues WiFi win8/8.1 driver from the deivce manager or program? Refresh and see whether win10 can reinstall auto with its build in one or not..restart few times..

If still cannot ,try use win8.1 driver and set that exe installer with compability mode win8 before install..

I'm having Broadcom 802.11n for Wifi. Qualcomm Atheross is actually the LAN adapter.

i cannot exactly recall.... usually what I did is I will get every single driver for particular OS I'm installing. But in the case of Win10, I was too lazy and I had good experience before hand with my desktop and SP3 that I think I didn't install a new one and just let Windows take care of it....

but when anyone ask me "should I download a new one" my answer will always be "yes"... The one that comes with Windows or Windows Update usually will try to be stupid beyond anybody's comprehension...
