[c-nsp] 802.11 on 871

I don't know for sure, but I have a few guesses.
1. Are you sure the 871 is a layer 3 device with respect to wireless? The Cisco 1400 series bridges we purchased a few years ago were layer 2 only. The IOS they came on them (12.2) will accept config like it was layer 3 router, they just don't work. Really messed me up (and the TAC) until the TAC supervisor told me they were layer 2 only. If this is the problem you will need to "bridge irb" and add a BVI interface. Let me know if you need a config.
There was some talk that they might upgrade the IOS for these devices (1400's) to support layer 3. Anyone know if that happened in IOS 12.3 Wireless Lan feature set?
2. BTW, your NAT looks wrong. FastEthernet4 is "nat outside" but you are specifying FastEthernet0 in your ip nat inside source ... command and FastEthernet0 is not configured.
3. Under ssid you might try adding "infrastructure-ssid optional" but I don't think that's the problem.
4. I don't know if the 802.11 radio for the 871 allows you to adjust the power put you could try something like:
power local cck 100
power local ofdm 30
your numbers will be lower and the units may be different.
on the radio interface.
Best,
leb
