to change a few things on the Linksys WAP11, and it works fine.
I get 11MB/s on channel 11 everywhere now, and was only getting 5.5
in the living room on the default channel, so IMHO it's a good idea
to try a few different channels.
I did manage to hang the AP entirely when changing its IP address.
The Linksys manual was correct regarding the default IP address and
password. You should change the latter.
