[AccessD] OT: Three routers, weird problems

You're gonna love this one.  The new router DHCP default begin ip address is 192.168.0.10 and the 
default end is 192.168.0.19.

NINE stinking addresses available by default.  All of my other routers have defaulted to 09-99.  So 
basically I just manually set the ending address to 99 and rebooted the router and voila, at least 
some of my issues are gone.  I was struggling for the last hour to get one of my laptops to get an 
IP address, it just wouldn't.  Now I know why!  Once I opened up the range it immediately grapped 
one, I didn't even have to do a release / renew.

NINE STINKIN IP addresses available by default.  It just never occurred to me to check that as I was 
setting it up.  I have never in all my years seen 19 used as the last available IP.
