9 +The EA8100 contains 2 firmware partitions. Flashing via the Linksys UI will only flash openwrt into one of the 2 partitions.

13 -* **Known issue**: 2.4Ghz wifi performance is really bad. You probably want to disable 2.4Ghz wifi.
11 +If your router currently has stock Linksys firmware, flash the "squashfs-factory.img" via Linksys UI. After you flashed the factory img one time, you should set root password (do not configure/restart), log in via ssh and download the "squashfs-sysupgrade.bin" into /tmp and run sysupgrade to flash this .bin to both firmware partitions.

13 +If you are on my 18.x below, doing sysupgrade to 19.07.x will not work. You have to manually mtd write the "squashfs-sysupgrade.bin" into the firmware1 & firmware2 partitions.

17 -**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 follow instructions to get the squashfs.bin flashed, then opkg update and opkg install luci.
15 +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.

19 -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.
17 +Wifi seem to work at 30-40MB/s with a MacBook Pro.

21 -How to flash if your router currently has stock Linksys firmware:
22 22  
23 -1. Flash the "**initramfs-factory.img**" via Linksys UI. Wait for it to start to reboot.
24 -1. Configure your computer to have IP in 192.168.1.0/24 subnet but NOT 192.168.1.1. (so, use 192.168.1.2.) Start ping to 192.168.1.1.
25 -1. Cross your fingers that the router boots openwrt. Otherwise keep rebooting until it loads the openwrt partition. (Usually 3 times max.) Wait a few minutes from reboot to let it load. If you get ping response from 192.168.1.1 it means openwrt loaded.
26 -1. Scp the "**squashfs-sysupgrade.bin**" into /tmp in the router. root@192.168.1.1. No password.
27 -1. Log in as root via SSH into shell. No password.
28 -1. **Sysupgrade the uploaded squashfs-sysupgrade.bin**. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
29 -1. opkg update
30 -1. **opkg install luci (the flashed images does not contain Luci)**
31 -1. Access LuCI via http:~/~/192.168.1.1/. You can now configure.
32 -
33 -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.
34 -
35 -Sysupgrade from 19.07.x to another 19.07.y will work. **HOWEVER: **sysupgrade will wipe entire firmware partitions! Backup your files/config before sysupgrade.
