Airport Express + Router access problem
I`m having trouble accessing my airport in my home network. I have a MacBook Pro (17-inch, Late 2011) connected via wifi to my ISP router.
My Apple Airport Express is connected to my ISP router via WIFI.
The problem is that I can´t reach my airport express through any wifi device on my home.
The only way I can reach my airport express is when I connect my MacBook to my ISP router through LAN cable. That way I can use my airport express with no problems. The second I unplug the ethernet cable off my laptop, I can´t reach my airport express anymore.
Could somebody help me out here? What am I doing wrong?
PS: These trouble started the moment my ISP game me a brand new wifi router. This problem did not exist with my older wifi router.
Thanks!!!
MacBook Pro (17-inch Late 2011), OS X Yosemite (10.10.5), 1 1tb Samsung SSD and 1 750gb HDD
