Opal Broken After Reset

I updated firmware. Then factory reset. Now I cannot log on to Opal using wifi password on the bottom of the router. Or goodlife.

I read on this forum that perhaps there is a bug in the new firmware that means the WiFi password is reset to a random number after this combo and that the only way to retrieve is to use an ethernet cable.

Is this really true? It seems like a bit of a majjor failing. I have no computers with ethernet ports and if it is, then I have no choice other to return it as not working.

Does your Opal still boot?

You can connect to its wifi?

You mean you cannot connect to the wifi, or you cannot login the router's admin panel?

It was the WiFi I oouldn't connect to. However I took it to work and now it's going again.

Maybe you changed power adapter, right?
