Hi all

My mac book pro retina will sometimes connect to my 5ghz network and sometimes it will not ;

when I check the system info I see when it will  not connect 5ghz that the UK channels are not supported on my Retina

Other times I boot up and they are supported ....

CRAZY stuff


See dump ; currently it will noy connect

    What router?

  • B12B12 Level 1 (0 points)

    its a dual band netgear ....



    I check my System Logs on my mac and its setting the country code to TW


    Either my Netgear is transmitting that country code ( although set to EUROPE in settings ) or maybe my neighbours is set to taiwan and my mac is picking up that beacon ,,,


    What a load of poop --- not sure how to fix !!

    Access the router's admin area and make sure you have set it up properly. The default access for that router is

    Name: admin

    Password: password

    if you haven't changed anything. Access from your browser. type in in your browser address bar.
