openwrt-22.03.6-ipq40xx-generic-linksys_ea8300-squashfs-factory.bin
Stage 1. This exact version, uploaded in the Linksys page. A newer OpenWrt file here will not start. Size 8,782,080 bytes, check code (MD5) f128bd3081217cfc7bd8a09c532ba0c0.
AJKFi-LINKSYS_ea8300_pisowifi-v3.82-factory.bin
Stage 3. Flashed from the OpenWrt page, after the command in stage 2. Size 16,910,336 bytes, check code (MD5) 5dc7e6c3f72646d1da47c36d271b3969.
Opens the Google Drive folder for this model only. Check the size and the check code above against the file you downloaded before you flash it.
One 2.4 GHz and two 5 GHz. The first 5 GHz reaches channel 64 and below, the second channel 100 and above, so between them they cover the whole band. All three come up as AJK PISOWIFI by themselves.
http://192.168.1.1 → Manual configuration → Login (password admin) → Connectivity → Manual → choose the OpenWrt 22.03.6 file → Start. It restarts into OpenWrt on http://192.168.1.1, no password, Wi-Fi off - stay on the cable.root@192.168.1.1 and run:fw_setenv kernsize 500000reboot. Once per router, ever. This tells the bootloader to read a 5 MB kernel instead of 3 MB; without it AJKFi will not start. Read the first warning below before you type it.http://192.168.1.1: System → Backup / Flash Firmware → Flash new firmware image. Choose the AJKFi file, untick Keep settings, tick Force, flash. It comes back on http://10.0.0.1:8080.It is fw_setenv kernsize 500000. Typing fw_setenv kernsize=500000 stops the router starting in a way no button fixes - it needs the case opened and a serial cable. Copy and paste it if you can. This is the only step on this router that cannot be undone.
It is built and every check on it passed, but no router has run it. Do your first one where you can watch it, not on a machine already out earning. If it does not start, step 06 brings it back - this board keeps a second firmware slot, so a bad image is recoverable without opening anything.
A newer OpenWrt file in the Linksys page will not start: its kernel is bigger than the 3 MB the bootloader reads until stage 2 fixes that. Use the file named above and nothing else.
The router holds two firmware slots and moves to the other one each time you flash. The Linksys firmware survives stage 1 in the spare slot, and stage 3 writes over it. After that, going back means bringing it to us.

http://192.168.1.1. From there you can simply flash the AJKFi file again. Keep the 22.03.6 file: it is the way back into a router that will not boot AJKFi.Stuck? Message us on Facebook with the model and a photo of the label before trying anything else - a second wrong step is what turns a fixable router into a repair job.
