I see a lot of people recommending devices with the MediaTek MT7621 chipset. In particular, I've seen Xiaomi routers, the D-Link DIR-860L B1, ZyXEL routers and ZBT mentioned.
However, the Xiaomi routers are difficult to flash, and the D-Link, ZyXEL and ZBT models aren't available here in Australia. The Netgear R6220 is another device, but I've read about there being issues with it.
I see people suggesting that the TP-Link Archer C7 is now too old and that IPQ40xx is a better option. However, the Linksys EA6350v3 doesn't have support in stable yet, which means that there would be no internet configured after flashing a snapshot build, since Luci wouldn't be installed. I've seen references to the Asus RT-AC58U having issues due to a lack of memory, though I'm not a heavy user, so I'm wondering if it's still an option.
I'm particularly interested in obtaining the fastest wifi speeds across my LAN rather than fast WAN speeds, as I'm only on a 50Mbps connection.
Would the Asus RT-AC58U offer better wifi speeds than the Netgear R6220? Are there any other recommended devices for my usage case?
