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 11 12 -* Wifi (5Ghz) seem to work at 30-40MB/s with a MacBook Pro. 13 -* **Known issue**: 2.4Ghz wifi performance is really bad.

(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. 16 +1. Flash the "initramfs-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 ping response from 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/.

Wait for it to start to reboot. 24 -1. Configure your computer to have IP in ##192.168.1.2/255.255.255.0##. 25 -1. Check that your router booted Openwrt by visiting [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You are in Openwrt if you see a white screen with message: "The requested URL /cgi-bin/luci/ was not found on this server." (Luci is not installed currently.) Do a reboot if you see Linksys UI instead, then check again when it boots. 26 -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>>https://winscp.net/]] if on Windows.
