Re: WEP and MAC Filter

The router is connected to the LAN via one of the 1-4 lan ports. There is no
wan connection to the router. Machines with wifi adaptors connect to the lan
via the router radio connection. Others are (obviously) wired.

I would be happy if someone could point out the correct sequence to be
followed.

From your confusing description, I can't tell how you have connected the
router into your environment. For a normal SOHO application, the WAN port
would be cabled to the cable/DSL modem, the 1-4 wired PCs would be
cabled to the 1-4 LAN ports, and the wireless PCs would be channeled
via 802.11G/802.11B to the radio end of the router; normally, all wired
and wireless PCs would be on the same LAN subnet, and all would access to
the 'net via the router's WAN port. Is this what you have, or want?

I don't know what you mean by "802/11b authentication". 802.11B is a
protocol and signalling mechanism used by some wireless nodes, just as
is 802.11G. Neither 802.11B nor 802.11G specify authentication. FWIW,
if all of your PCs are new enough to support 802.11G, I suggest disabling
802.11B in the router, since pure 802.11G will give better performance.

To simplify your LAN while troubleshooting, I suggest not using MAC filtering.
After everything works, you can turn MAC filtering ON and ALLOW only those
PCs that you want to access your LAN (and/or your pipe to the WAN). Note
that MAC filtering offers rather limited security, and probably is not
worth the effort. To secure the wireless segment of your LAN, use WPA2
or WPA or (at least) WEP; pick the best (WPA2 if possible) method that all
of your wireless PCs can use. For a new network, I suggest getting it
all working without wireless encryption, then turning on encryption in the
router and one wireless PC, then in each other wireless PC; it is easy to
screw up when trying to enter the same passphrase into the router and the
PCs, so do it one PC at a time and expect to do it over a few times (until
the difference between password and passphrase becomes clear).

As for DHCP, I would use it across the board from day one. It is very easy
to set up, in the router and in wired and wireless PCs, and it is pretty
robust. If you have problems and want to experiment, you can use DHCP on
some PCs but not others: with the DHCP server set to its normal range of
192.168.0.x (100 < x < 150), you can manually enter an IPA which is in the
same subnet but outside of the DHCP range (e.g., IPA=192.168.0.55 with a
mask of 255.255.255.0); how you assign that IPA to a PC depends on the
OS and the specific device driver for that PC.
