installing firmware during stretch install

[pcr1]

Hi.  I am trying to install stretch onto my AMD64 box using wifi. During 
install I get a missing firmware message asking me to supply 
rtl_nic/rtl8168g-2fw on removable media.  I found rtl8168g-2fw on my 
laptop in lib/firmware/rtl_nic and copied it to a folder I labled 
rtl_nic on a flash drive.  Then I ran the install again on my AMD box 
and clicked yes when asked for the missing firmware after I plugged in 
the flash drive.  Did I do that right?  My install still does not 
configure the network and says my network hardware may not be working 
properly.  All help is appreciated.
