udhcpc eth0?  Then I ifconfig the resulting IP number and am online?
No gw if this is only one network.

The library is not encrypted and no longer requires a key.  I am online 
via the laptop and the WPC11 ver 4, after doing a site survey and choosing 
the library (53% signal strength).  Windows does not have udhcpc or dhcp. 
The Linksys software apparently includes it.

After copying the pcmcia wireless modules for 2.4.31 I will be back again 
with linux.  First an Opera for Windows download in less than 30 minutes.

Thanks for all the ideas.

The router may not be fully working.  I cannot access the promised website 
with a browser like I can on the Maxgate via wireless or wired connection, 
or ping it like I can the Linksys which has no website.  I do get a 
wireless connection with the card but would need to reset factory defaults 
to be able to change the IP number via serial cable and Kermit.  The Cisco 
software detected the Cisco router IP number which was not the default.
For the other two routers it associated the card with 0.0.0.0 but then I 
had to type in the actual 192.168.0.1 to run tests.  ???

Y  This model has no web page like the Maxgate does and the Cisco should.
You need to use their Windows software to change from default 192.168.0.1
The browser tries for a while to connect then gives up.  I can ping this 
address via straight cable (to one of four ports on built-in hub), not 
with crossover cable (like I could on the Maxgate to PC port, vs Hub port 
with straight cable).  The Cisco does not even ping, which is probably why 
it was donated to the local rummage sale - the serial connection works 
(except it has a password) but the wired and wireless ones do not ping or 
provide webpages.  The router does have a strong signal - is it usable for 
something such as connecting wireless computers to each other?

No login window, lookup fails.  I will try the Cisco with blank and admin,
rather than root and blank.

To pick up an external signal would I need to run udhcpc and change the 
router IP number, and then I could plug things in over a wired network and 
share a connection?

Wondering if I can skip the wireless pcmcia and use the router instead to 
pick up a county-wide wireless signal and pass it along to my local 
network via the ethernet ports, assigning my computers all something on 
the same network (change the last part of the IP number).

It helps a lot - will try blank and admin on the cisco via Kermit serial.
And udhcpc in linux practicing on the Maxgate, which says it does dhcp.
