How to set up multiple access points?
Sun Apr 26 03:47:59 PDT 2009
I currently have a single access point (hostapd/madwifi) and am
considering adding another in order to increase the coverage area.
I haven't really found any documentation on how to do this (except for
some references in the hostapd docs to handoff).
What I _think_ I need to do is:
- The 2nd AP has the same SSID as the current-one but operates on a
- Whereas I haven't been using bridging so far (my current access point
routes between the wired and wireless home network segments, as well as
acting as the DSL modem), I think I will need to bridge the two APs'
wireless segments together. Since I want to continue routing between
wireless and wired segments, I think I need to do this by setting up a
tunnel between the APs across the wired network, bridging it on each end
to the wireless segment.
- Since I'm using WPA2-PSK with a separate key per client MAC I will
need to rsync the key file across between the two APs.
- Because of the bridge/tunnel setup all of the routing and firewalling
will still only be done on the current AP, not on the new-one. Also only
one dhcpd instance is required (the one on the current AP), which will
serve both APs.
Does this make sense?
How does handoff work, or what do I need to change in order for handoff
to work? (I note that according to Wikipedia IAPP has been withdrawn by
the IEEE, so should I be using it?).
