Huasifei WS1208V2

"I updated my Huasifei WS1208V2 router, but I think I messed up something because I can no longer access the page with the IP address 192.168.1.1. I have tried multiple methods mentioned on the internet, but none of them have worked. When I connect the router to my PC, it does not recognize it at all and the IP address 192.168.1.1 page does not load. Do you have any advice on what I should do?"

What image did you load? If you installed the snapshot, the LuCI interface isn't available. But you can install it, or install the 23.05.2 release (probably easiest to simply use the sysupgrade file via the command line).

https://firmware-selector.openwrt.org/?version=23.05.2&target=ramips%2Fmt7621&id=huasifei_ws1208v2

Can you ping 192.168.1.1? If so, that probably means the router is working but you did install the snapshot...
You have installed a snapshot image. Read the link for instructions how to install Luci, which is not installed by default in snapshots.

I can’t load the 192.168.1.1 anymore. I tried the rest bottom multiple times it didn’t work
The ping give me timed out

What was the exact filename of what you installed? And what process did you use to install it?

Here is the exact filename I uploaded: Huasifei-WS1208V2-full-GO2024-03-14-upgrade.bin
I selected the third option in the left (orange color)

And after this, I am not able to access the 192.168.1.1 anymore, I tried all the possible options but no luck

How is that file related to Openwrt?

You'll have to ask the maintainers of Breed since this is entirely unrelated to OpenWrt.
