Said another way, I'm looking to eliminate a box (access point) because I need wireless connectivity aboard a small boat. The idea is to have one regular PC (or laptop) running FC3 contain a wireless nic, and that nic IS the access point to allow one or more other devices (laptops, PC's, etc) access to that servers samba shares, etc.
The dlink site suggests its possible( http://www.dlink.com/products/?sec=0&pid=308 ), but I'd like to know if its possible under FC3. On that page the statement :
Like all D-Link wireless adapters, the DWL-G510 can be used in Ad-Hoc mode to connect directly with other 2.4GHz wireless computers for peer-to-peer file sharing ...
is what I'm referring to.
Ad-hoc mode is not the same as acting as an access point. In ad-hoc mode, all wireless devices connect to each other simultaneously. In AP mode each device connects only to an access point. Most if not all of the linux wireless drivers support ad-hoc mode, which should be sufficient for your requirements.
mode master ? not really tested:
$ man iwconfig
mode Set the operating mode of the device, which depends on the net-
work topology. The mode can be Ad-Hoc (network composed of only
one cell and without Access Point), Managed (node connects to a
network composed of many Access Points, with roaming), Master
(the node is the synchronisation master or acts as an Access
Point), Repeater (the node forwards packets between other wire-
less nodes), Secondary (the node acts as a backup mas-
ter/repeater), Monitor (the node acts as a passive monitor and
only receives packets) or Auto.
Example :
iwconfig eth0 mode Managed
iwconfig eth0 mode Ad-Hoc
# iwconfig eth2 mode master
# iwconfig eth2
