Correct. You'll eventually roll over after 2^32-1 ... this has nothing to do with wifi btw - look at ethernet devices :) [snip irrelevant use of the station interface] > root@OpenWrt:/tmp# iw dev wmon0 set channel 1 Is 'wmon0' still up at that point? It should work then, not sure why it wouldn't, but it's certainly not an iw problem but more likely a kernel problem. Since openwrt also has a fair number of patches I'd ask you to please retest on a regular kernel first, or report the bug to them. johannes
