Kali Linux on Latitude 5510 - No network card detected, no WIFI

No ethernet card detected and no WiFi Latitude 5510

I went through the following steps:
1. I downloaded kali linux from their website
2. I used Rufus to create a bootable usb drive using the downloaded iso
3. I rebooted and started installing the iso on an empty partition with 80 GBs

I faced 2 problems during installation:

1. The Network Card was not detected and I was prompted with the following message:
"Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as USB stick or floppy.
The missing firmware files are: a long list of Wifi related drivers (no clue were to get them though)
If you have such media available now, insert it, and continue.
Load missing firmware from removable media? (No, Yes)"

2. The network card was not listed and I could not choose any network card manually

I did the following:

1. As advised in many forums, I just chose No when loading missing firmwares. I read many forums telling that we can install the missing files later after booting.

2. The installation continued and when I didnt know which card to choose from the list, I chose: No network adapter

Many solutions suggest that I need to do some commands like: apt get update and apt get upgrade. This sounds great but I do not have internet on my machine. No WiFi and no ethernet cable connected.

Some of the linux commands such as "ifconfig" are not working as well. I assume this is because not being able to install the default or top10 tools during installation.

I am stuck now and I can not find more help any where.
