Several WiFi cards Connected to One WiFi card.

xanthax

This might sound as a bit of a strange question but i haven´t found the direct
answer anywhere so i try it here.

I wanna set up a gentoo server as a router betweeen my inner and outer network.
And i want to use the gentoo server with a WiFi card in it as AP, so here is the question.

Can one single WiFi card handle multiple connections to other WiFi cards or does it only
work in the way one WiFi card to another one WiFi card ???
Since i have plenty of computers that have to connect trough this server via WiFi i just
had to know before i bought the stuff.

HI

If your Wi-Fi card can correctly handle the "master" mode, then it would be detected as an access point by others wireless card, so it can manage several connections.

The known cards correctly handling this are :

All hostap compatible cards plus madwifi one's (Atheros chipset). According to your chipset (hostap compatible or atheros) you should install hostapd whether or not. For instance, I have a TI ACX100 based card managed by hostap, and a atheros one (madwifi driver) but for this you just need the wireless tools.

I hope this is the answer you expected ?

Almost the answer i was looking for

Or it was but now you got my attention on another thing. Does all WiFi cards work in "master" mode ?
Or Specificly does this "PCI Netgear RangeMax, WPN311IS, 802.11g (108Mbps)" ?
cause this is the one i was looking to buy...

And while im on it is there a possibility to make a MAC based "whitelist" for the WiFi connections ?

Thanks

I was unable to find which chipset this card uses. I hope it's an atheros one but I'm absolutely not sure. If you are looking for a "master mode" capable device, you could buy Dlink DWL-G520 (not 520+) which is Atheros based and which can handle master mode.

To make an ACL based on MAC addresses, it is possible do it whith iptables and/or arptables.

Hi There,

Does anybody know how to make an access point of: D-Link DWL-G520+ with the acx100 driver?

If I set de card in "mode Managed" I get:

wlan0 IEEE 802.11b+/g+ ESSID:"STA6DB9AA" Nickname:"acx100 v0.2.0pre8"
Mode:Managed Frequency:2.412 GHz Access Point: 00:00:00:00:00:00
Bit Rate=54 Mb/s Tx-Power=15 dBm Sensitivity=1/3
Retry min limit:7 RTS thr:off
Encryption key:off
Power Management:off
Link Quality=33/100 Signal level=6/100 Noise level=0/100
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

The access point has no adress.

Does anybody know if it is possible at all? Or will it never work with this card?
Or am I missing something?

I am fearly new with this, so any help would be appriciated.

Thanx. :-)
