How to share wifi(internet) from laptop?

[arivas_2005]

Greetings
a curiosity.
It will be possible to pass Wi-Fi internet from a mobile (point 1) to a laptop (point 2) and then distribute the Wi-Fi signal from a laptop, but the laptop only has one (1 card) wlan. (In the same wlan would enter signal (from 1) and also shared (point 2) to the others mobiles).
There is a way to configure laptop so that it receives a signal and at the same time shared (as hostpot), with only a(1) Wi-Fi card.
[ Or it is not possible! ]
My thanks to your comments
(I try to graph the idea)

The following suggests to me that it may be possible, but I have to leave you to try it out and report back please if you succeed:

Maybe. Note the "sharing" segment.

The *crux* however depends on whether your card supports AP.

Code: Select all

Supported interface modes:
		 * IBSS
		 * managed
		 * AP
		 * AP/VLAN
		 * monitor

Kinda cool that mine ($20 or so US greenbacks) DOES!

I wish I had another device to test with.

Greetings..

I still have not advanced in my situation
Today it is like this:

===> Internet ==> eth0 ==> PC ==> wlan0

I want to share internet through wlan0.

I found a small script that creates the AP well and is seen on the clients, but does not share the internet
send error
Not Internet sharing.

and when starting the AP, the internet goes down by eth0 in the pc

Hopefully you can review it and give me the idea to share the signal with the internet.
I use the command

create_ap STUDENT STUDENT54321

I attach the script (just remove the .gz)
Thanks!

This post does NOT address your script. But from looking at your diagram, it appears you may be trying to set up a LAN proxy for your users. Not sure if your intent is a mere proxy or a caching-proxy.

I dont see anything in the modern forum for a Puppy proxy setup and use. Will try to find something if that is what you want for your LAN community.

Well
what I try is to pass the cable internet through eth0 and share it to several computers or mobiles in a classroom through Wi-Fi (something like the telephone routers).
With the create_ap command cell phones and PCs recognize the AP, but the internet from the eth0 wired computer is not broadcast by the AP.

Through PC1 you enter the internet with cable.

In 2 clients, they receive wifi. Clients in 2 if they recognize the wifi but the Internet signal does not pass from pc in 1 to clients in 2

Hello @arivas_2005
An AP presence, as you indicate, suggests that the #2's are getting their IP addresses from a DHCP server, somewhere.

Usually, there is a DHCP server somewhere. The AP connects to that DHCP server and passes connection ability to devices which use it. All routing information is gotten from the DHCP server.

Is your phone a DHCP server while your PC is the AP? If the #2 units cannot route, then your DHCP server is not sending the info normally needed for internet access. And, as such, the #2 units are not getting the information for it telling it how to route.

AP's are relay nodes. They make no decisions except to intercept and pass-thru all LAN requests.

Does this give an indication of where the problem may be?

Please check to see if ALL #2 units can ping aI-netll other #2 units. AND check to see if the #2 units can ping the DHCP server ... not the AP... the DHCP server. In most home network cases that server is also your Gateway to the internet.

Hope this helps

EDIT:
Forgive me as I am having a little trouble understanding your physical setup you are trying to get to work. Please correct my understanding of what you are showing. Do you have

• a Hotspot connected to your PC via a USB cable or via its Wifi?

• If its Wifi, do you have a 2nd Wifi in the PC that your AP software is using?

• If its USB, what is providing the DHCP services to your LAN users, both wired and wifi...since your PC is acting as an AP?

Where/what is your router in the picture below?

Beware: Some carrier Hotspots have a limit on the number of connections (LAN IPs) it will serve. Some are only1 while others ???.

ALSO: See this for cell-phone configuration ideas.

If you follow that, there is no need for an AP.

Hope this helps

Hello
Thanks for the quick reply.
Excuses for confusing description.
Well
I have comp.(1) with cable internet with eth0
I want to distribute signal wifi (wlan0). with/from comp.(1)
-----
From what I read, the script create_ap uses hostapd, dnmask and iproute packets.
then
script create_ap creates an AP that is seen by each celphone and other comps.
each celphone and others comp. get the ip of the comp(1)--(as AP)-- well.
this works fine.
but, internt form comp.(1) does not pass to every celphone and other comps.
That's my problem.
Then, How I do redirect the internet from comp.(1) to other comps and celphones?
I have read that make to a "nat"(eth0 nat wlan0), but I don't know how to do it
this:
......................... comp (1) .............................. other comps
internet -> eth0 -> redirect internet to - >> wlan0 - >> all clients
................................................................... celphones
my thanks

Seems a little clearer.

1. You have a cable company as your ISP delivering Internet service thru its device, a modem.

2. You have a ethernet cable from the ISP's modem to your PC, you call #1.

3. You have a wireless card in your #1.

Given that configuration, you want your PC #1 to extend internet from your PC #1 for others in your home; namely #2s.

If that is correct, what you "really" want is NOT AP software. Instead you want to make your #1 an "internet router". Doing this will allow 2 things for you:

1. All wifi devices can ping each other and share information, internally in your home

2. They can reach the internet thru your "router"

I am currently unaware of any PUPPY that is designed as a router OOTB and will have to look around. There are distros on Distrowatch that will turn a PC (as in your case "#1") into a router. None of which I have ever used.

Maybe someone else, here on the forum, has experience in setting up a router distro on a PC.

Hope this helps.
P.S. Your "AP" reference threw me for a loop. What you want is a router function running on a PC...not AP.

create_ap is the easiest way that i found to create a hotspot/bridge . I easily used my wifi card to join a network and share said network as a hotspot.

After here's a script i used to use. Depends on yad, dnsmasq, hostapd, create_ap (in fatdog repo or on github).

@arivas: Have you identified your Puppy version or its kernel number?

Not all Puppy kernels have been built to do what you need.

The Starter Kit's kernel will do this.

Are you running a firewall on any of these machines?
