Enable DFS for OpenWRT
Aim is to enable DFS for 5GHz wifi band. Until today we found no usable solution to integrade DFS suipport into OpenWRT. Without DFS there is no official 802.11n outdoor channels support.
In the following we will log our approach to (try to) enable DFS.
Compile trunk of OpenWRT
On 2014-01-24 we made SVN checkout of OpenWRT trunk with rev. 39385. All compiled well.
