using linux laptop as a wifi router?

I'm just wondering if it is possible to use a linux laptop with wifi as a wifi router. I have DSL coming in directly to the laptop, and want to share internet access with other wifi-enabled devices. Is this possible?

I found while googling, but it is a few years old, and not exactly newbie-level.

Hi -

Short answer: Sure!

Longer answer:
Q: exactly what hardware did you want to use?
a) DSL modem (for internet connectivity)
b) Laptop (has an RJ-45 plug to connect to your DSL modem)
c) what else???

Q: exactly what are your goals?
a) Do you have multiple PCs you want to share the internet connection?
b) Are they going to be on a (wired) switch or hub?
c) Do you have something like a Linksys router to broadcast a Wifi signal?

Q: How exactly were you going to broadcast Wifi?
Most laptops can *receive* a Wifi signal ... but cannot *broadcast*.
Perhaps you have a Linksys router?
Or perhaps your DSL modem doubles as a Wifi base station?

In general: Yes, Linux can be used to take advantage of whatever hardware, and whatever configuration, you want.

But we need more details to answer your question.

@paulsm4 Thanks for the reply! Sorry I was not more specific. I have an Acer Aspire One netbook with Atheros AR2425 wifi. I'm plugging the DSL modem directly into the RJ-45 input to the Acer. I want friends' laptops and smartphones to be able to see my Acer as if it were a wifi router (with WPA2, if possible). I have no other hardware (no linksys, belkin, etc..)

>> Most laptops can *receive* a Wifi signal ... but cannot *broadcast*.

Hrm... if the laptop cannot act as a "hotspot", then I guess I cannot do this. Is there no way around it?

Thanks again for the reply!

Question No stupid questions?

If my notebook can not transmit how is this getting to my wrt54g? I have seen a commercial answer to this question and that linux can do it. So how do we get the Artheros to work to hit the wrt54g?

This would seem to just be a adhock network with the security disabled?

Any progress on this issue? Seems to be an interesting problem. I am not sure if the wireless network adapter can handle multiple connections at the same time.
