Ooops I didn't realize that right away, indeed I'm trying to setup WiFi AP and hostAPD (which is really just "host AP Daemon") or alike is a must. The next question would be which option should I use then? 1) good olde HostAPD 2) its -mini sibling 3) wpad 4) its -mini sibling > > Another minor issue is that USB dongle gets recognized a bit late > > so that automatic "wifi detect" gets already executed and > > "/etc/config/wireless" isn't created.

May I get a reference to an example of that workaround? -Alexey _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
