12 +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.
13 +
14 +How to flash:
15 +
16 +If your router currently has stock Linksys firmware:
17 +
18 +1. Flash the "**initramfs-factory.img**" via Linksys UI. Wait for it to start to reboot.
19 +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.
20 +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.
21 +1. Scp the "**squashfs-sysupgrade.bin**" into /tmp in the router. root@192.168.1.1. No password.
22 +1. Log in as root via SSH into shell. No password.
23 +1. **Sysupgrade the uploaded squashfs-sysupgrade.bin**. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
24 +1. opkg update
25 +1. **opkg install luci (the flashed images does not contain Luci)**
26 +1. Access LuCI via http:~/~/192.168.1.1/. You can now configure.
27 +
28 +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.
29 +
30 +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.
31 +
32 +Since [[19.07.03>>https://www.codepowered.com/openwrt/v19.07.3/linksys_ea8100/]], as of 19.07.04:
33 +
34 +* Wifi (5Ghz) seem to work at 30-40MB/s with a MacBook Pro.
35 +* **Known issue**: 2.4Ghz wifi performance is really bad. You probably want to disable 2.4Ghz wifi.
