I got Asus rt-ac86u a year ago but was only able to set it up recently and couldn't get it to work. Rt-ac86u WAN light is red, initially it is white and then after few seconds will turn red. I connected rt-ac86 WAN to Telus modem T3200m LAN1 (also tried LAN2-4 nothing) using cable provided and also tried different cables. I factory reset rt-ac86u multiple times but still the same. I disabled both modem T3200m port1 bridge and wireless radio (also tried port1 bridge and wireless radio enabled) but same issue. I even factory reset modem T3200m and redo everything thinking it might resolve the issue but Rt-ac86u WAN light is still red. I could not even do http://router.asus.com error is site can’t be reached. I hard-wired my pc to modem T3200m and could see rt-ac86u (shows as unknown device) from list of active devices and could see asus2-4g and asus-5g from network list but Rr-ac86u WAN light is red. Does anyone know what am I missing? Thanks.
Are you trying to get to the Asus router's web interface while connected to the T3200M? That won't work. You need to connect to the Asus router directly using one of the LAN ports on the Asus router.
If I connect directly to asus lan and access asus web interface, would asus wan light turn white? Isn't it connection between asus wan (should be white light) and telus lan established first before accessing asus web interface? Thanks.
