Replacement for RT-AC87U

[arachnida]

Hi,

I need a replacement for my ASUS 87U router and AP. Especially the AP is not working as it should, the discusion about that is somewhere else on this forum.

In the shop where I will return both units I can buy a:

Netgear Nighthawk X4 AC2350
Netgear Nighthawk R7000
Linksys EA6900
TP-Link Archer C7 V2
Linksys WRT1900AC
Linksys E8350-EJ.

Is there any of those routers that has proven to work, so no network loops and NAT problems?

Thanks for your advice!
