New owner of a wt7600nex and trying to determine what the difference is between the two.  I'm trying to get my chromecast operational but can't seem to get both to AA and it to work at the same time.  Feel like I'm not doing something right.  I would assume I need to turn mobile hotspot on on my phone, share that to the HU, and then share the HU's wifi to the chromecast, right?

Oh and I've tried the darn bypass at least 30x with no success.  I've watched the video how-to and for w/e reason it just doesn't seem like it wants to take for me - SOOOO frustrating!!!

Ok so I got the bypass done.  Works great. 

Still don't understand the hotspot vs access point stuff.  I was able to get the hotspot to detect my mobile hotspot but then the access point does not beam internet access as I would suspect it would.  Does anyone know what I might be doing wrong?
