Question Upgrading to 11g router, want to use old 11a router for "public" access

Comments on the following welcomed/encouraged:

Is this a good idea or not? My plan is to tie the old router into a port on the new one and assign the DMZ IP on the new router to the IP of the old one (with me so far??? ) The old router would be on a different subnet than the new one, and would only be used for internet access for friends, relatives, nice neighbors, etc. (No broadcast SSID, WEP security) No access at all to my home network. My primary reason for doing this, actually, is that I have an OLD laptop with a 64bit wireless card in it that I only use on very rare occasions, and I don't feel like spending the money to upgrade it to 11g. I am also considering only having the old router plugged in whenever I want to use that laptop, or when someone I know might need internet access. I haven't completely decided yet.

Thanks in advance for any comments/suggestions (or even flames )

I hace mine hooked up like this:

Internet Modem>Wan Port Old Router>Wan Port New Router

Reason why is that way, the new router is firewalled against the old 'public' router. I have 'dhcp server assign addresses' enabled on the 'old' router, that way the 'old' router gets a IP address from my ISP, and the 'new' gets one from the 'old' one. I also change the 'mode' on the 'new' router to 'router' from 'gateway'

Kinda hard to explain......

Opinion 1: Even with 128 Bit WEP and disabled SSID broadcast, access is still vulnerable. It's painstaking (a few hours worth of effort) - but doable. This means that untrusty neighbors may try filesharing or using your connection for other shady efforts... if there's a legal issue - they'll come back to you because of your Public IP address.

Opinion 2: Opinion 1 really isn't a big deal, as the number of people capable and willing to crack WEP is low - and the number of them with 802.11a equipment is even lower.

Just presenting Opinion 1 as something you may want to consider if you haven't already.

Thanks for the comments, guys. Honestly I hadn't even thought about the legal stuff, but that's definitely something to consider; glad you mentioned it. My neighbors are spaced pretty far apart, and I know most of them pretty well, but you never know when Jr. will want to play on someone else's playground where Mom and Dad can't see him (or her..) Think I'll just worry about getting the NEW router set up for now, and worry about the old one the next time I want to use that laptop...

Thanks again.
