10 -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.

12 -How to flash:

14 -If your router currently has stock Linksys firmware:
15 -
16 -1. flash the "squashfs-factory.img" via Linksys UI, cross your fingers that it boots openwrt when auto rebooting. Otherwise keep rebooting until it loads openwrt. (Usually 3 times max.)
17 -1. access LuCI via LAN. (It's at 192.168.1.1 so you should set connect your computer and configure your computer with an IP on same subnet eg 192.168.1.2/24). Set root password so that SSH server starts. (do not configure/restart.)
18 -1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router.
19 -1. Log in via SSH.
20 -1. Sysupgrade the squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
21 -
22 -If you are on my 18.x below, sysupgrade will not work. You have to manually mtd write the 19.07 "kernel-initramfs.bin" and boot into it, then sysupgrade. Back up data before mtd write!
23 -
24 -Subsequently sysupgrade from 19.07.x should work but it will **not **save config! Back up your config and other files in the router before you sysupgrade.

26 -Wifi seem to work at 30-40MB/s with a MacBook Pro.
