Well in case he lags, just input the modem IP address and do it yourself. Doesn't take more than 5 min.I need to catch the Comcast guy who comes out in my area for repairs, he said he would do it for me. I also have a link to have them bridge it. I really need to do this one of these day as their signal is nowhere near as good as mine and they'll even admit it.
Sorry for the thread jack OP.
OP make sure you setup AC wireless as well, HUGE difference. I actually have the AC66U, its a bit newer but still pretty much the same Asus from above. This mostly what I avg on a wireless device, its worth it.
