Looking for the most reliable, fast router

[Caveman]

Currently have an Asus AC2400 Dual band gigabit router as my main router hooked to a Comcast modem upstairs where my Cable comes into the house. Every room in the house has Cat 6 network drops.

Downstairs in my office there is an Asus RT-N66U router plugged into the wall and serves as a second wifi to service that area.

About once or twice a day, the upstairs router gets disconnected. This can happen for 30 seconds to 5 mins. When it happens I generally just switch routers for a few minutes and then switch back to continue using the upstairs router.

Question is: Why do these drops happen? Do I need a new router? What can I do to help mitigate? If a new router could fix it, what is one of the best, most reliable gigabit routers out there?

Wait, if your main router is down how do you get internet downstairs? Sounds like your downstairs router is not in ap mode.

I am assuming this setup

Comcast - ac2200 - rtn66u

Yea, sounds like double NAT

Hmmm... Good questions. I'm a network noob and IIR, I posted here a few years ago for advice and JackMDS answered the mail -- perhaps it was with the very link that he just provided. I must have read something and just tried it and it worked so I just kept using it... I actually have 4 routers since each of the 2 routers has a 2.4 and 5GHz bandwidth it can utilize. When the main router upstairs drops service, I switch to the 5.4GHz side. I'm assuming that the way the circuity is handled for a dual router us that if one bandwidth can take over when the other one drops out, it will... I think that is why my downstairs router would keep functioning (because only 1 of the 2 upstairs bandwidths would fail).

I don't know what causes the main router to drop out but (unless I'm imagining things) it's generally in the vicinity of high bandwidth usage when it will drop out.

One router with 2 frequencies does not make it become two routers, you only have 2 routers, you don't have 2x2 = 4 routers, period.

Turn one router into AP mode like JackMDS suggested and uplink it to the main router using one of the LAN port.
