I was looking at a cheap home router to replace my aging Archer C6 v2 (US), which can not achieve my new upstream link of 800+ Mbps, even with software flow offloading.
Is the Xiaomi AX3000T really the best option for its price, despite all the hassle mentioned at https://openwrt.org/inbox/toh/xiaomi/ax3000t ?
Some AX3000T devices come with a new NAND flash chip:
Winbond 25n01kvzeir. This chip is incompatible with the official stable OpenWrt 23.05.4 image and uboot! Don´t try to flash it without checking your chip! However SNAPSHOT build is fully compatible and tested with both flash chips since Aug.13
New AX3000T devices with stock firmware version 1.0.84 or newer have received updated hardware that is temporarily incompatible with the OpenWrt image until support is added. There is no possibility to install OpenWrt on RD03 for such devices
And on top of all that, you've to exploit a SSH vulnerability in an older firmware version in order to install OpenWrt.
Cudy WR3000 has nearly the same hardware, but with 16 MB flash instead of 128 and I can only find it for sale in my country at Amazon, for almost double the price of a Xiaomi AX3000T.
