Is the Intel(R) Centrino(R) Wireless-N 2230 the original card that came installed by factory?
What exactly are the issues you are experiencing after you upgraded to Windows 10*?
The newest software and driver package we have for the 2230 adapter is version 22.214.171.124, and it comes either as a driver only download or comes with the PROSet 18.12.0 software/driver package. There isn't a specific "Windows 10" driver for this adapter, but the Windows 8.1 driver should be able to be used for Windows 10. Please check with HP to see which driver version they suggest for use with your HP ENVY TouchSmart m7-j020dx Notebook PC with Windows 10. Does HP say your system is ready for Windows 10?
I had the same issue with my Lenovo e430.
I noticed this issue caused by Forticlient vpn software.
Uninstalled the vpn software but problem still remains.
After spending hours downgrading back to win 8.1, then upgraded to win 10 without any vpn client software installed.
Wifi works normally using version 126.96.36.199
After that I installed Forticlient vpn software , and wifi problem came back.
Even after uninstall the Forticlient the wifi problem still there.
I solved this issue by rollbacked the intel driver, in my case to version 188.8.131.52.
My wifi is back to normal.
Tried to install back to Forticlient vpn software and I encounter no wifi issue using version 184.108.40.206 up until now.
Hope this helps
