hardware version D3, FW 4.10 and 4.11 same problem.
i tried with 4 wlan adapters: two of them support 802.11b/g, they always work find no matter which settings. the other two support 802.11b/g/n, as default "n" is enabled, so does DIR-615, both wlan adapters can be connected to DIR-615, they get their LAN-IP, but they can access neither DIR-615(no respone to ping) nor internet. but if i disable "n" mode either in the adapter or in DIR-615, everythin works fine, of course only with 54mbit max.
so what can i do to use the n mode? thanks!
