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. 11 + 12 +How to flash: 13 + 14 +If your router currently has stock Linksys firmware: 15 + 16 +1. Flash the "squashfs-factory.img" via Linksys UI, Wait for it to start to reboot. 17 +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. 18 +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 response from ping 192.168.1.1 it means openwrt loaded. 19 +1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router. root@192.168.1.1. No password. 20 +1. Log in as root via SSH into shell. No password 21 +1. Sysupgrade the uploaded squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots. 22 +1. opkg update 23 +1. opkg install luci 24 +1. Access LuCI via http:~/~/192.168.1.1/. You can now configure. 25 + 26 +If you are on my 18.x below, sysupgrade 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. 27 + 28 +Sysupgrade will wipe entire firmware partitions! Backup your files/config before sysupgrade. 29 + 30 +Subsequently sysupgrade from 19.07.x should work. 31 + 32 +Wifi seem to work at 30-40MB/s with a MacBook Pro. 33 + 34 + 35 += 18.x = 36 + 6 6 9bebafcb5dfe37f25285fa18fb8bfe7b68011267 (with wifi support) Download: 7 7 8 8 * [[initramfs-kernel.bin>>attach:openwrt-ramips-mt7621-linksys_ea8100-initramfs-kernel-9bebafcb5dfe37f25285fa18fb8bfe7b68011267.bin]]
