Help: Trying to Network Computers on WLAN/LAN

Purchased a new SMC (SMC2804WBRP-G) router replacing another (older)
SMC router connecting a notebook (via WLAN) using a USR 802.11G
PCcard, another computer via LAN and the Internet through a cable
modem.

Everything to/from (using either or both computers) the Internet works
fine. However, while I used to connect (via "the" Network) between
computers to transfer files using a FTP server program in the LAN
connected computer and a FTP client program in the WLAN connected
notebook, I can not get the same combo to "see" or "talk" to each
other using the new router. The server software has a log in it which
doesn't show any activity at all when I try to connect using the
applicable computer's IP address which I get using the program,
winipcfg.exe in each computer. This method worked using the previous
router/card combination.

In desperation I even tried to use LapLink Gold programs in each
computer to try to connect via a "network" connection but since the
initial successful attempt, have been unable to connect since.

According to SMC technical support, their suggestion is to deactivate
(and un-install) any firewall software (I use Zone Alarm in both
computers) and to turn off the internal firewall in the new router
(previous unit didn't have such) I haven't tried this yet because
this seems ratrher radical and since I firmly believe in a firewall
while connected via cable to the Internet, I believe isn't prudent.

Any suggestions to connect up the two computers over my WLAN/LAN or
examples of successful networking between computers on the inside of a
LAN/WLAN would be appreciated.

SMC Tech Support is correct, if only for debugging purposes. Turning off
the firewalls will tell you if those are the problem. Then you can work on
finding the exact settings that make/break your connection. From earlier
posts in this newsgroup, it appears that merely disabling Zone Alarm may not
be sufficient; you may have to uninstall it.

Even before disabling the firewalls, you could look in the firewall logs.
If they are blocking traffic, they should be logging that fact. This will
also give you information as to what settings are problematic.
