I did change all channel one by one but still cannot work.
any mbp user encounter the same issue please let me know .
Try these settings below,
802.11 Mode : 802.11gn
Channel Width : 20 MHz
Channel : 1 ( or 11, or 6*. 6 being the default for most device should be avoided, or try it last)
WPA Mode : WPA2 Only
Cipher Type : AES
Can any of your device connect to other wifi?
Did you enable your DHCP server in your WAP?
Did you enable your MAC filtering?
Did you restart all your devices (ie. router, WAP, MBP, iPad, iPhone, etc.) every time you make any changes?
Did you save your changes?
Can any non Apple device connect to your WAP?
