  1. Greetings, I followed your tutorial after I ran into issues with my Asus RT N12 and getting it to pass internet. The steps you show are the same steps I took to set the router to extend mode. The issue I’m experiencing is that I cannot get out to the internet when connected to the extended network. It shows that connections are good in the Asus UI, can Connect my phone and laptop to the extended network, but it will not reach out to the internet. When connected to original network I can ping the extender and I can ping original router from the extender. I wondering if the original router has some kind of port block or something going on preventing the extender from doing its thing. The main router is provided by my ISP Spectrum I believe it’s called a Wave2. Any advice would be greatly appreciated!

    • Hi, Try to use the Same security type as using in main wifi router, or see if you mobile getting IP address from repeater device which provided by your main AP.
