Supporting an older 11b client in the DMZ TBerk 07-10-08

I have a N adapter connecting via G, and other adapters/clients
connecting via native G, but I have an orphan without any 80211g
option- it can only connect via 11b.

The router has options for WEP OR WPA/2, but not both. (Not that
I'd default to WEP if I can help it anyway.)

My thoughts are to implement the DMZ option and connect another,
limited use router that is set to 11b and WEP to get this 'littleguy'
on the net for now and then access.

Toss me some 'how to avoid pitfalls' if you can re: two routers, one
in the DMZ, 11b/WEP, etc, etc.

DMZ won't do anything useful. The strange definition used by wireless
router manufacturers has nothing to do with the real dual firewall
(bastion host) DMZ. The way it's implimented, it's really an IP
address, where all port forwarding defaults.

Duz your unspecified model mystery access point have provisions for
setting up more than one SSID? If so, setup one SSID for WPA and the
other for WEP. That's what I do using DD-WRT. If not, get a seperate
wireless access point and set it up for WEP. Turn it on or off a
needed.

1st off, Jeff; Thanks. (I see you answering w/o a lot of snootiness,
something unavoidable in other forums sometimes.)

2nd, I am talking about a Linksys WRT54G.

3rdly, the idea of getting a second wifi router is likely what I was
going to do anyway, (I don't believe the standard firmware in the
linksys will support two separate SSIDs).

going to be scouring for a cheapy 11n I can 'sperament with.

I don't do snootiness. However, I do arrogance, abuse, humiliation,
sarcasm, puns, and humor quite well.

>2nd, I am talking about a Linksys WRT54G.

Which WRT54G hardware version? Look on the serial number tag.

DD-WRT v24 firmware supports more than one SSID.
<http://www.wi-fiplanet.com/tutorials/article.php/3710791>
I'm not sure if the micro version (required for v5 and v6 WRT54G
routers), will do multiple SSID's.

>3rdly, the idea of getting a second wifi router is likely what I was

Correct. The stock firmware only does one SSID.

You don't need Pre-802.11n unless you're doing wireless video or
massive wireless file transfers.
