8 +Openwrt 19.07.4 for EA8100 is here!
10 10  
11 -The EA8100 contains 2 firmware partitions. Flashing via the Linksys UI will only flash openwrt into one of the 2 partitions.
10 +Since [[19.07.03>>https://www.codepowered.com/openwrt/v19.07.3/linksys_ea8100/]], as of 19.07.04:
12 12  
13 -Download the "squashfs-factory.img" if you want to flash via Linksys web UI. After you flashed the img the first time, download the "squashfs-sysupgrade.bin" and run sysupgrade to flash this .bin to both firmware partitions.
12 +* Wifi (5Ghz) seem to work at 30-40MB/s with a MacBook Pro.
13 +* **Known issue**: 2.4Ghz wifi performance is really bad. You probably want to disable 2.4Ghz wifi.
14 14  
15 -You cannot sysupgrade from 18.x to 19.07.x.
15 +UPDATED 2020-12-10 the 19.07.04 builds now includes LuCi! Follow these instructions:
16 16  
17 -Sysupgrade from 19.07.x will not save config! Back up your config and other files in the router before you sysupgrade.
17 +1. Grab initramfs-factory.img from [[https:~~/~~/www.codepowered.com/openwrt/v19.07.4/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-initramfs-factory.img>>https://www.codepowered.com/openwrt/v19.07.4/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-initramfs-factory.img]] and flash it via Linksys UI.
18 +1. Wait for Openwrt to boot so that you get to LuCi at [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. Do NOT configure yet! It's not ready.
19 +1. Then grab squashfs-sysupgrade.bin from [[https:~~/~~/www.codepowered.com/openwrt/v19.07.4/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin>>https://www.codepowered.com/openwrt/v19.07.4/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin]] and flash it via LuCi
20 +1. Wait for it to reboot. Now you can configure!
18 18  
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.
19 19  
24 +Sysupgrade from 19.07.x to another 19.07.y will work. You can also upgrade via LuCI.
25 +
26 +{{warning}}
27 +Upgrading images will wipe entire firmware partitions! Backup your files/config before sysupgrade. It will reset router ip to 192.168.1.1.
28 +{{/warning}}
29 +
30 +--**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.)--
31 +
32 +--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.--
33 +
34 +--How to flash if your router currently has stock Linksys firmware:--
35 +
36 +1. --Download the "**openwrt-ramips-mt7621-ea8100-initramfs-kernel-factory.img**" from link above, and flash it via Linksys UI. Wait for it to start to reboot.--
37 +1. --Configure your computer to have IP in ##192.168.1.2/255.255.255.0##.--
38 +1. --Check that your router booted Openwrt by visiting [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. It is in Openwrt if you see a white screen with message: "Index of /." Do a reboot if you see Linksys UI instead, then check again when it boots. --
39 +1. --Download the "**openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin**" from link above, and upload it into ##/tmp## in the router via SFTP. You can use [[winscp>>doc:How to WinSCP.WebHome]] if on Windows. [[root@192.168.1.1>>mailto:root@192.168.1.1]] (No password).--
40 +1. --Ssh into [[root@192.168.1.1>>mailto:root@192.168.1.1]] (no password). Use [[putty>>doc:How to Putty.WebHome]] to ssh if you are on Windows.--
41 +1. --In the ssh shell run: ##sysupgrade /tmp/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin##--
42 +1. --It automatically reboots after a short while. Log in via SSH again. Check you are online by pinging 8.8.8.8 when in SSH.--
43 +1. --Run: ##opkg update##--
44 +1. --Run: ##**opkg install luci**##--
45 +1. --Access LuCI via [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You can now configure.--
