TP-Link RE455 IP error

Installing and Using OpenWrt
1

Hello everyone. I'm new around here. On Friday I updated the firmware of my TP-Link RE455 with OpenWRT. Although the flash was successful with apparently no errors, when I try to access the extender from the browser it keeps telling me that the IP address 192.168.1.1 is refusing the connection. The straight (non-crossed) network cable is new Cat.8. The Plugs are perfect and do not appear to be broken in any component. Unfortunately, at the moment I have no other network cables to try. Anyone have an idea? Could it be that the firmware flash went wrong? Are there methods to do a second programming? Thanks to all those who will and can help me.

Thank you all.

Emanuel

installed a snapshot image ?
they don't come with luci / webUI.

grab the RE455 sysupgrade file from https://downloads.openwrt.org/releases/22.03.5/targets/ath79/generic/
(win)scp it to the /tmp folder, and via ssh (putty) run sysupgrade /tmp/filenameoftheimage

Hello and welcome.

Which file (link if possible) did you upload to your router?
Can you ping the router?
If you can ping it, try to ssh into the router.
