7 +Thanks to [[this patch>>https://github.com/openwrt/openwrt/commit/97df795b78dc572ea2ec105ccbf8af27cc4b4d8e]], EA8100 is now supported from openwrt 21.02.

9 +The 21.02 release is currently at RC3. You can get it from [[openwrt firmware selector>>https://firmware-selector.openwrt.org/?version=21.02.0-rc3&target=ramips%2Fmt7621&id=linksys_ea8100-v1]] page.

11 +Both 2.4Ghz and 5Ghz wifi are working fine.
12 +
13 +If you are already on 19.07, please do not sysupgrade with 21.02 sysupgrade.bin, because sysupgrade.bin format in 21.02 is not supported by 19.07 sysupgrade utility.

31 +Follow these instructions:

34 +1. Access Linksys UI (default [[http:~~/~~/192.168.10.1/>>http://192.168.10.1/]]). Flash **##initramfs-factory.img##**. It will reboot.
35 +1. Wait for Openwrt to boot so that you get to LuCi at [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You might need to restart your PC so that it gets a ##192.168.1.x## address from openwrt. Once you get LuCI, do NOT configure yet! It's not ready.
36 +1. Flash **##squashfs-sysupgrade.bin##** via LuCi
20 20  1. Wait for it to reboot. Now you can configure!
21 21  
39 +For kernel modules, replace the relevant link in your ##/etc/opkg/distfeeds.conf(% class="small" %) (%%)##with this:

22 22  If you are on my 18.x below, sysupgrading to a 19.07 image will not work. You have to manually mtd write the 19.07 "kernel-initramfs.bin" into the nand and boot/log into it (192.168.1.1), then sysupgrade.

26 26  --**Images do not contain LuCi! (The build process doesn't include it for some reason I have not yet time to figure out.)** You need to have the **squashfs-sysupgrade.bin** flashed, then install LuCI. (See instructions below.)--
27 27  
28 28  --The EA8100 contains 2 firmware partitions. Using the Linksys UI will flash openwrt into only one of the 2 partitions. The booting process switches partition every few boots, so if you want to always boot into openwrt then you have to flash openwrt into both partitions.--
