My Netgear Nighthawk R7000 running Asuswrt-Merlin firmware is still serving me well after 8 years but I'm wondering if it's worth looking at upgrading it. I'm visiting China soon and wonder if I should pick up a router there. I'm not well versed in networking hardware. What would be good and are they easy to flash to openwrt, etc? Xiaomi AX9000? AX6000? BE 6500Pro?
For comparison, what are good local options that are a worthwhile upgrade from the R7000? Things like the ASUS RT-AX86U Pro AX5700 seem quite expensive given that my point of comparison is that I picked up the R7000 for $165 8 years ago.
If you account for inflation, using RBA calculator $165 back in 2014 is equivalent to $209.10 in 2023 rates. High end ASUS routers have always been expensive, there's a bit of a price premium for ASUS branded stuff. I have personally stuck with ASUS for almost a decade because their stuff just works without a hitch.
There is a high end Wifi 6E router with Tri-band that you can grab in the $220 range if you don't mind TP-Link (and have TGG Commercial access). If you don't, consider the GL.Inet Flint 2. (Probably sold in china without VPN support)
