Hi Rajkumar After long time waiting, I found the ccmp ip address can be gotten. but it's very slow. After ping the AP from pc, the packet loss rate is very high. So the reason why the network cannot work should be because the DHCP is time out. So there is my question, Do the nohwcrypt=1 is working for CCMP? If not, I guess the packet is lost in firmware because of slow/wrong packet encryption/decryption
And I have tried a laptop, it can connect by both mode; So I think It's not AP issue. And maybe it is not cooperate with other APs, even we do not know.
