I just joined cloudy nights to answer ggkids.
On iAstrohub's side you can disable router and dns advertising , commenting out options 3 and 6 in /etc/dnsmasq.conf. Here's mine :
... interface=eth0 dhcp-range=10.0.0.2,10.0.0.2,255.255.255.0,12h #option-dhcp=3 #option-dhcp=6
This way you can establish wifi connection from your laptop to iah without losing your (wired) internet connection. option 3 and 6 aren't particulary useful on the device.
Furthermore, you can run an http proxy on your laptop and perform web queries from iah. With squid running on my laptop connected to both LAN and iah :
export http_proxy=http://10.0.0.2:3128/ root@rk3066dev:/etc# export http_proxy=http://10.0.0.2:3128/ root@rk3066dev:/etc# wget http://www.google.fr/ --2014-04-22 00:14:47-- http://www.google.fr/ Connecting to 10.0.0.2:3128... connected .... 2014-04-22 00:14:48 (464 KB/s) - `index.html' saved  root@rk3066dev:/etc#
