Have you used the web portal at 192.168.1.1/192.168.0.1?
I used IP Config to figure out the address, it's just odd that they don't offer in the documentation. They seem to rely on the portal working properly. It's just confusing and typing 192.168.1.1 brings up a Microsoft interface rather than a GUI. If you don't have the internet working the default way to get online with unit gets quite confusing. As bad as the D Link interface was, I really don't like this at all.
I had installed that already. It is just what it says, a Genie and it really doesn't access the full controls of the router. They partnered with Disney (why?) to create parental controls, which is the only way to add schedules. The scheduling available in the base unit will shut off the entire Wi-Fi radio only and you can't even have 2 different schedules for say the weekend and weeknights.
I have an R6700 and have none of the issues you describe. I don’t use the MAC filter feature you are describing, but I certainly have never configured it any other way than through the website on my PC. I have a USB HD for a super simple media server connected to it and it routes on average 6-8 wireless devices at a time and three Ethernet gigabit LAN ports and I’m on fiber with a 1000/1000Mbps connection and I’ve restarted it maybe 2-4 times while trouble shooting in maybe a year and a half of uptime.
I don't know what you are talking about. The performance of the router is not in question at this time and I have no issues related to that. What I'm upset about is the "Smart" features that don't do much without an app or a paid service. On my D Link router, you could set schedules based on the mac address. This is really handy to prevent the grandkids from staying up all night playing on the tablets/PS4. I have 2 schedules, one for weeknights and one for weekends that allowed them to stay up a little longer.
I have partially gotten around this with the Kindles because they have excellent parental controls and will turn off based on time alone. The iPad nor the PS4 doesn't seem to have any way to do this. I got a bit frustrated last night when I am looking this stuff up and saw people saying things like "Well, the PS4 doesn't promote bad parenting, teach your kids how to obey". Yeah, right. They are kids, and not bad ones, but unfortunately their mother never taught them properly and let them pretty much do what they want to. I've had them for almost 2 years and I am still trying to get them to do basic things like turning off lights...
