The SMC2602W is a PCI card with a PCMCIA wireless card (based on the Prism2 chip) mounted on it. However, it doesn't use a PCMCIA interface, so any information or tutorials you have that tell you to load the pcmcia-cs drivers are wrong if you are using this card.
After putting the card in you PC, you'll see something like the following from lspci -vv:
00:0a.0 Network controller: Unknown device 1638:1100 (rev 02)
Subsystem: Unknown device 1638:1100
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR-
If your intent is to use the card as an access point to your
wired network, then all you have to do is
- compile the hostap_plx.o module. For
me, this took a small modification to the Makefile (to tell it
where to find the kernel source, something you may not need to
change) and then make plx.
- After that, insmod
hostap_plx.o loads the module and you have an interface to
play set up for NAT and whatnot.
- Now, set up your dhcp
daemon. On debian, you've got to set /etc/init.d/dhcp
to point to the right interface. Also, modify your
/etc/dhcp.conf to serve up IPs on your wireless network
(say, 10.x.x.x).
- After starting dhcpd, make sure
that your laptop (Windows, Mac, or whatever) gets an IP address
when you are in range.
- You still won't be able to get out
to your wired network from your laptop, though, so you need to
set up NAT. The simple way to do this is iptables -t nat -A
POSTROUTING -o eth0 -j MASQUERADE (where eth0 is
your interface to your wired network.
- That's It! You
probably want to look
at the Linux IP masquerading HOWTO for information on
securing your network.
