Question Internet sharing with two wlan cards?

Good day all,

I run into a problem. I use internet via wlan whereby the antenna for wlan0 is connected with a long cable because in my house is no reception. Right now I'm forced to distribute that internet to other devices via a second wlan card (wlan1) in the same computer, means, I need to set up an AP to achieve that and to use mentioned connection from wlan0.
After reading and re-configuring and lots of code writing I can not reach the point that wlan1 is giving what I need.
I'm free to use any Linux distro since the computer has nothing else to do than sharing the internet (and if possible giving access to shared folders in other connected computers). The wlan cards are capable of running in AP mode.
Please assist me with that. I did something similar a few years ago when I successfully shared a 3G connection with one of those wlan cards, so I believe that it suppose to be possible as well with a incoming wlan connection.
Any advice about the right way to do this is highly appreciated.

Hello and welcome to LQ.

I get the feeling that Debian has a simple way to do that.

Pretty much any disto should be able to do that with iptables. Some web sites kind of go all out on some other ways like hostapd.

Pages like this might help.

Dieter Tief, what you are looking to do is commonly referred to as "using your computer as a router."

Do a web search for "linux computer wireless router." You will find a number of articles. I hesitate to recommend one, as this is not something in which I have any firsthand experience. (If you leave the word, "wireless," out of the search string, you will find even more resources, as wired Linux computers have been used as routers since the earliest days of Linux.)

Here's one:
