Dual Mode Operation: One WLAN interface for both 801.11 infrastructure & OLSR?
2007-09-05 06:52:52 GMT
Here are some notes from trying to mess with dual mode operation.
Got the dual mode operation partly working.
1. ath0 in adhoc mode
2. ath1 in ap mode
Note that the adhoc mode interface needs to be created before the ap. If you do the other way around, the hardware does not allow you to add it. (sorry im not geeky enough to figure that out ). I just tried this on an intuition (and a couple of caffeine shots) and it seemed to do the trick.
I got OLSR running on the ath0 and seems to work ok. But still have not figured the ap mode as yet on ath1. I do get some MAC layer exchanges (arps) so I know the interfaces ARE ok. But face a bummer on the IP layer.
RouterA <----------> RouterB <--------------> Laptop1
<--- pings ok ---> <---pings not ok -->
<-------- arps ------>
Hope someone in the list can help.

As said, I did not try it out myself but try this:
Is that what you were looking for?
