Where is my wifi adpt. ? Debian 9
 

My Dell 1555 laptop HDD failed. replaced w/1TB HDD. Booted w/thumb drive,D9 installer ? Direct connected to my router for full install. single user,single OS, guided format for HDD partition.
Works well w/lan direct. Internal wifi adpt. , Intell N630 ... dual ch.AGN. I looked 4 a device mgr. type of hardware id program online and in the D9 adm. Handbook. No luck. The Discover program in D9 found the VGA screen,trackpad etc. but not my wifi adpt. I went to Intell dwn.ld.s for N630 driver. Downloaded an extracted but will not setup ? I suppose the adpt. could have failed but how do I check it Debian 9 ? Thanks for any input . JP

Usually in linux

than you look for something like this: example my asus g75vw notebook

and usually you see also when it is properly setup which kernel driver is used: ath9k

this is second try:
when you know if the kernel is properly loaded / or kernel module is properly loaded for your wireless
than you can setup your wifi

e.g. /etc/wpa_supplicant/wpa_supplicant.conf
+ dhcpcd

not sure on how networkmanager handles this as I have hardmasked it for other reasons.

this is more a distro issue than, on how they setup their boxes. also systemd may be different

The driver should be in kernel. You probably need firmware.

Thanks I'll try both. JP
