@Kevin_Z  Thanks for the reply. I actually only need one to replace our old Asus RT-AC68U router which has Dual WAN + Load Balance / Failover feature with support for USB 3G/4G Modem. Since its DOS Protection and Firewall is not that good, I'm looking for a replacement Gigabit router that has those features too but hopefully much better. I was aiming to get something that has more RAM and powerful CPU as well. I thought the Link Aggregation feature of the TP-Link Archer AX6000 can work as a second WAN? So it does not and it also does not have Load Balancing... But do both routers still have the Advanced Security feature for DOS Protection (see pic below)?

I guess if I go with TP-Link, I have to get a separate hardware from the WiFi Router to also have Load Balancing and Firewall features is that right? ...or does TP-Link have something that has all of these features combined in one hardware? Maybe the Archer AX11000?

@Kevin_Z Yes, I just bought the Archer AX6000 instead. But learned too late that it had no DOS protection just recently in this post I've made. It's really difficulty knowing what software features most of TP-Links products have because it constantly changes even for similar models. When I do research online, I find old reviews and articles that say differently and when I buy the product, that is the time I actually get to use it and learn some things have changed.

I wish TP-Link did not remove the DOS Protection for their new Routers even with HomeCare. Because its one of the features that other popular consumer Routers seem to be missing. When I look at my old TP-Link Routers, they seem to have more powerful built-in features compared to the new models. But of course WPA3 and WiFi 6 is important too although most cannot fully utilize them yet.

If there are direct DOS attacks, I'm not sure if HomeCare will be able to handle that since i think it mostly protects only from known Antiviruses and Malware? So there is now no basic zero-day attack protection for the new Routers.
