21 -* **Known issue**: 2.4Ghz wifi performance is really bad. You probably want to disable 2.4Ghz wifi.
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.

14 +**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.bin flashed, then opkg update and opkg install luci.

16 +How to flash if your router currently has stock Linksys firmware:
29 29  
30 -Follow these instructions:
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.

32 -1. Download ##[[initramfs-factory.img>>https://www.codepowered.com/openwrt/v19.07.7/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-initramfs-factory.img]]## and ##[[squashfs-sysupgrade.bin>>https://www.codepowered.com/openwrt/v19.07.7/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin||style="background-color: rgb(255, 255, 255);"]]##
33 -1. Access Linksys UI (default [[http:~~/~~/192.168.10.1/>>http://192.168.10.1/]]). Flash **##initramfs-factory.img##**. It will reboot.
34 -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.
35 -1. Flash **##squashfs-sysupgrade.bin##** via LuCi
36 -1. Wait for it to reboot. Now you can configure!

46 -Sysupgrade from 19.07.x to another 19.07.y will work. You can also upgrade via LuCI.

56 ---How to flash if your router currently has stock Linksys firmware:--
57 -
58 -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.--
59 -1. --Configure your computer to have IP in ##192.168.1.2/255.255.255.0##.--
60 -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. --
61 -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).--
62 -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.--
63 -1. --In the ssh shell run: ##sysupgrade /tmp/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin##--
64 -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.--
65 -1. --Run: ##opkg update##--
66 -1. --Run: ##**opkg install luci**##--
67 -1. --Access LuCI via [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You can now configure.--
