Bought this to replace the old netgear router (Wi-Fi 4). While these new speeds are much better, it keeps dropping the 2.4 GHz band for only two devices. While it could be the age of these devices, they consistently lose a signal when Smart connect is on. It can take hours for the signal to fail, or it can take minutes, but the signal WILL fail. Turning off smart connect seems to solve the issue. I hope the smart connect issue can be patched smehow, because it's a nice idea. Considering returning it for an older model that might be more reliable. Three bands just might be too much to program for right now.
