I installed OpenWRT to my router.
After this, because Spectrum only supplies internet to routers with whitelisted MAC, I started to change settings.
While this, I changed my router's network setting (I can't exactly remember what was that) from static to DHCP. And I immediately became unable to access it through ssh firstname.lastname@example.org.
I'm looking for several solutions:
Is there any way to completely reset OpenWRT settings?
Is recovery through TFTP possible? I tried it but didn't get any good results.
Can I just recover it to factory settings with hardware controls?
If it's not able to debrick, I'm going to buy ASUS RT-AC66U B1. Does it work nice?
Allow OpenWrt to boot up fully (the "gear" LED stops blinking and is on steady). Press and hold the reset button for longer than 5 seconds then release. After a short time all the lights should blink out and the router reboots to default settings.
