Help Pls - Clean install network off - using usb adapter?

Hello, I've tried more times than I can count to update a friend's old laptop. It was stuck on 1703 and never installed 1709 due to a no longer supported intel network wifi link. I finally did a fresh clean install of 1709 and ultimately purchased a TP-Link WIFI adapter and all was fine with 1709. Laptop network ability turned off.

So now I want to go from 1709 to 1803 and downloading and updating of course fails again.I want to try a clean install again. Here is my question.

I made a DVD with version 1803 (she has no usb boot). So, should I turn on the useless network switch or leave it off during an install? Also should I simply remove the USB WIFI adapter during the install or does Windows fresh install need to have it plugged in during the process? I will be formatting of course so the WIFI adapter probably won't even be able to work???

I do also have a 1709 install DVD so if all else fails, I can re-do that version but I'd like to try for 1803 just once.

Thank you for your advice, Donna

During install, do not check the check for updates box and skip connecting to networks. Leave the USB network adapter disconnected until Windows is installed and settled in. Then connect it if it is needed.

Worked Perfectly, did not have uncheck "updates" because I had turned off networking in the bios and I had pulled the USB and to top it off, I deleted all current partitions. Thanks for the perfect response and quickly too.

Glad it worked! Now, if you have Windows 10 installed and networking working on the USB adapter, I would go back into bios and turn on networking and see if Windows will pull a driver for the adapter included on the motherboard.
